Part Fifty Five Q&A 1351 - 1375

1351. I have a 2003 LE PT. Recently the heated seat stopped working on the driver side.  I've checked all of the fuses and relays, they seem to be fine.  The switch for the heated seat blinks while in “lo” position and will not produce any heat.  I think it is the heating element in the seat but I figured I would throw this out here to see if anyone has experience the same problem. - Anonymous, from the USA.

The Flashing LED indicators on the driver side switch indicate that a fault exists in the driver side of the system. If the switch “HI” LED indicator is off, and the switch “LO” LED indicator is flashing, this is an indication of “NTC Sensor Value Out of Range”.

The heated seat module uses the temperature sensor input to monitor the temperature of the seat, and to regulate the current flow to the seat heating elements accordingly. The heated seat sensor cannot be adjusted or repaired and if it is found to be faulty, the complete heated seat element must be replaced.

Diagnostics and replacement procedures are available in the service manual or through the Pit area on the site.

 

1352. I have a 2001 LE PT with 106k miles. After the car sits outside during an extended period of rain (say a day or two), it will start just fine but begins to shift erratically and run rough for a few miles before it calms down and begins to run OK again. The engine light came on the other day, and the mechanic said there was an error code recorded in the Throttle Position Sensor circuit. The TPS seemed to be working OK, but he replaced it anyway. That was a few days ago and today the car exhibited the same problem as before. Where should I look now? It seems to me like water is causing a short somewhere? – Mark, from Maryland.

A DTC indicates that the PCM has recognized an abnormal condition in the system. DTC's are the results of a system or circuit failure, but do not directly identify the failed component or components. You didn't provide the DTC you received and I have to wonder whether the TP sensor was the actual issue, or if there's another unresolved issue that is causing the problem you're experiencing now. With 106k miles on the PT you don't mention the maintenance you performed and I'm not clear what you mean by shifting erratically, but rough running can be attributed to a number of things, including plugs, wires, throttle body, fuel injectors, etc. If the issue is occurring mostly during rainy weather I would start by checking the ignition wires, than the condition/gap on the plugs.

 

1353. I have a preowned 2002 LE PT with 80k miles, which I purchased from a Chrysler dealership with exhaust system modifications already done to the car. Two months later, the check engine light came on. Brought in for servicing and EGR valve was replaced. Three months later, check engine light came on again. I scanned the PT with a personal OBDII reader and fault code P0401 came up. With split tailpipes I am getting what I think is a lot of backpressure when I downshift. (The exhaust makes popping sound), Sounds cool but could this be the problem? – Blair, from Canada.

The EGR system reduces oxides of nitrogen (NOx) in engine exhaust and helps prevent detonation (engine knock). Under normal operating conditions, engine cylinder temperature can reach more than 3000°F. Formation of NOx increases proportionally with combustion temperature. To reduce the emission of these oxides, the cylinder temperature must be lowered. The EGR system allows a redetermined amount of hot exhaust gas to recirculate and dilute the incoming air/fuel mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion. The electric EGR transducer contains an electrically operated solenoid and a back-pressure transducer. The Powertrain Control Module (PCM) operates the solenoid. The PCM determines when to energize the solenoid and the exhaust system back-pressure controls the transducer.

There are a number of PT's that utilize aftermarket dual exhausts. In most instances they do not cause an issue, however in this case I would check the back pressure. You'll find the procedure in your SM, or in the Pit area.

Exhaust System

A P0401 DTC is “EGR System Failure” - Required change in air/fuel ration not detected during diagnostic test.

P0401 – P0403 are not uncommon faults. 99% of the time they translate to a bad EGR valve and solenoid.

See the Top 10 Issues Guide for additional information on the EGR Valve.

1354. I have a 2001 LE PT with 112k miles. I'm getting a hard miss on acceleration when under a load - up a hill, low speed and higher gear - that seems to be accelerator position related. If I back off it goes away - but so does the acceleration! Seems good at idle and at highway speed. I'm getting no codes out of the self diagnostic modes. Your thoughts? Thanks. – Jim, from Tennessee.

When the OBD II system detects a misfire that exceeds "normal" limits, it sets a DTC that corresponds to the misfiring cylinder. If a DTC isn't set the problem you're experiencing either isn't a misfire, or not severe enough to trigger the DTC. Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load and or operating conditions. I would start by checking the plugs, wires, fuel injectors and EGR valve in that order.

At 112k miles I would pay particular attention to the condition of the plugs. If the plug is fouled, you've found the source of the misfire, but you still have to determine what caused the plug to foul. Heavy black oily carbon deposits would tell you that the engine is burning oil. The most likely cause is worn valve guide seals and/or guides, but worn rings and cylinders can also allow oil to enter the combustion chamber. A leakdown or compression test will help you determine if the oil is getting past the valve guides or the rings. If the cylinder shows little leakdown or holds good compression when a little oil is squirted into the cylinder (wet compression test), it would tell you that the engine needs new valve guide seals and or guide work.

Follow up from owner - I would have thought a plug issue would give me a defect code, but it was the plugs. They were all "clean" so no issues with injectors or oil leaking into the cylinders but the gap was excessive on at least two of them. Replaced with double platinum Champions and it's running great again. Thanks for your help!

 

1355. I have a 2002 BE PT with 36k miles. I changed the battery about 2 weeks ago and now the speedometer does not work. It counts mileage, but not the speed. Could it be a fuse? – Sean, from Pennsylvania.

The instrument cluster electronically drives the speedometer, odometer, fuel/temperature gauges, and tachometer. The gauges are not serviced individually, thereby requiring complete replacement of the cluster if one indicator or gauge becomes defective. Since you did not provide the self test results for the IC I assume that it checked out ok. If everything else is operable on the cluster the interior fuse which feeds the IC is probably ok. Check the IOD fuse (fuse #17, 20amp) in the PDC under the hood; it feeds the IC fuse in the interior fuse box and a number of other circuits. If it's ok there is a diagnostic available through the Pit area for checking inoperable gauges, which can help you isolate the issue, or you can have your local dealer handle it for you.

 

1356. I have a 2005 2.2L DCI Turbo (LO) with 6k miles. Extreme pressure is required to depress the clutch pedal in order to start the vehicle. I suppose it is some sort of immobilizing idea. I have an injured left foot which makes it extremely unpleasant when starting up. I don't know if this is standard on all vehicles or peculiar to UK specification. – Richard, from the U.K.

Were not exposed to the export model here in the US and most domestic owners who write have automatic transmissions. I would suggest that you check with the dealer to determine if this is normal. The export models utilize two switches on the clutch pedal however excessive pressure should not be necessary to activate the switches and or to depress the pedal.

The clutch interlock/upstop switch is an assembly consisting of two switches: an engine starter inhibit switch (interlock), and a clutch pedal upstop switch, which is only used on the export 1.6L and 2.2L Turbo Diesel PT. The switch assembly is located in the clutch/brake pedal bracket assembly.

When the clutch pedal is fully depressed, the pedal lever (LHD), or the master cylinder push rod (RHD), closes the clutch interlock switch, completing the signal circuit from the PCM and closing the ground path, allowing engine starter operation. The interlock switch is not adjustable.

With the clutch pedal at rest, the clutch pedal upstop switch is closed, allowing speed control operation. When the clutch pedal is depressed, the upstop switch opens and signals the PCM to cancel speed control operation, and enter a modified engine calibration schedule to improve driveability during gear-to-gear shifts. The upstop switch is not adjustable.

 

1357.We have a 2005 GT (LO) Convertible with 3k miles. We just got E85 fuel in town; I went through the manual and cannot find any reference to E85 fuel. In checking with various web sites, they all want you to check your manual to see if you can burn ethanol with 15% gas added too it. All the articles speak to the fact that Chrysler's engines will burn this fuel. Thanks for your help. – Mark, from Illinois.

The SM does not mention E85, however it does indicate that Gasoline / Oxygenate Blends with a 10% mix are safe to use with the PT. “Some fuel suppliers blend unleaded gasoline with oxygenates such as 10% ethanol, MTBE, and ETBE. Oxygenates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.” Given that E85 utilizes a mix of 15% gasoline and 85% ethanol, I would suggest checking with your local DC dealer first.

Follow up from owner – The dealer indicated that E85 ethanol is not compatible with the PT's 2.4L engine.

PTDIY additional follow up - Ethanol is a liquid alcohol that is blended with gasoline to produce a fuel that is friendlier to the environment than gasoline and can be used in virtually any gasoline-powered vehicle manufactured after 1980. Most gasoline-powered vehicles can run on a blend consisting of gasoline and up to 10 percent ethanol that is known as "E-10 blend," and available at a number of service stations throughout the U. S. and Canada.

Some (FFV) vehicles are specially manufactured or converted to operate on an ethanol blend that contains up to 85 percent ethanol and at least 15 percent gasoline. The 15 percent gasoline is needed to assist in engine starting because pure ethanol is difficult to ignite in cold weather. This E-85 blend cannot be used in standard gasoline engines, but FFV engines designed to run with a high ethanol blend can also operate using gasoline when necessary. 

E-85 vehicles use an on-board sensor to detect and automatically adjust for the fuel mixture being used at any given time. To handle the high alcohol content of E-85, modifications are needed to an engine's intake valves, fuel-injection system and ignition system. The engine must be made of alcohol-resistant materials (zinc, lead, magnesium, aluminum and certain plastics and rubbers that are commonly used in gasoline engines can be broken down by alcohol). These vehicles also require stainless steel storage tanks and fuel lines. To overcome the problem of lower energy content, manufacturers have equipped E-85 vehicles with larger fuel tanks. All North American automakers make Flexible Fuel Vehicles that can run on gasoline or on blends of up to 85 percent ethanol and 15 percent gasoline. As of 2003, the National Ethanol Vehicle Coalition estimated that approximately 2 million Flexible Fuel Vehicles have already been sold in the United States, although many buyers remain unaware that they may fuel with E85. DaimlerChrysler offers FFV models in all 50 states for the Chrysler Voyager/Town & Country, Sebring, Dodge Grand Caravan, Durango, Ram Pickup, and Stratus model.

1358. I have a 2001 LE PT with 39k miles. When I try to maintain a steady speed the engine rpm fluctuates up and down about 300 rpm. – Gary, from California.

There's not enough information to suggest a specific cause, and I assume that you haven't recorded any DTC's since none were mentioned. The PCM adjusts engine idle speed through the idle air control motor to compensate for engine load, coolant temperature or barometric pressure changes. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations (brake, park/neutral, air conditioning). It could be one of these components or as simple as a dirty throttle body. I addition, keep in mind that the PT's A/C compressor operates in both Mix and Defrost, or a blend of these Modes, even if the fan switch is not in the A/C position. This dehumidifies the air to help dry the windshield, but will also cause some rpm fluctuation each time the compressor kicks in.

 

1359. I have a 2002 DC PT with 51k miles. I've never really run the A/C, and the first time I ran it on a road trip I noticed water dripping down on the passenger side, soaking the floor under the glove compartment. – Aaron, from Texas.

That's where the HVAC system and evaporator are located in the PT. Condensation that accumulates in the evaporator housing is drained by a tube through the dash and on to the ground. This tube must be kept open to prevent condensate water from collecting in the bottom of the housing. When it's clogged it can overflow into the passenger compartment. You'll find a service guide in the service manual, or we have one available in the Pit area on the site.

 

1360. I have a 2001 BE PT with 68k miles. I noticed that my brake lights stayed on after the car was turned off and keys were taken out. I tried to lift the brake pedal thinking it was stuck, but that didn't help. I started the car and it operated fine, but the brake lights stayed on. I thought it might be on a sensor because I could not find a button that controlled the brake light around the brake pedal. So to reset the sensor I disconnected the battery positive lead next to the fuse box under the hood. This of course turned the brake light out and I left it disconnected for more than an hour. When I connected it the brake lights came back on and I noticed an additional problem - the instrument cluster seemed to be dead. None of the lights on the instruments were lit and the gauges did not move as well as the dome light was out. I twisted the dimmer with no result. Everything else seems to work so I thought it was a fuse. Looked for one correlating to the instrument cluster but was unable to find anything until reading through your Q&A section. If I read it right fuse #13 seems to correspond to the cluster and dome light. That fuse does not look damaged. I also tried the Self-Test A with no result. My guess on the self-test is that the cluster has no power, thus no reading. My worry is that I have damaged the BCM. Thank you for your time. – Lance, from Utah.

The brake lamp issue may be a problem with the brake lamp switch located under the instrument panel, at the brake pedal arm. It has three internal switches controlling various functions of the vehicle. Its main function is to control operation of the vehicle's brake lamps. Other functions include speed control deactivation, brake sense for the antilock brake system and brake sense for the brake transmission shift interlock. We have received a few reports of other failures by owners. A diagnostic guide is available through the Pit area on the site to check the switch, or your local dealer can handle this for you. Do not attempt to replace or adjust the switch without reviewing the OE instructions.

Never disconnect the positive battery lead without first disconnecting the negative lead. You may have damaged the IC by doing so. The BCM is part of the IC, not a separate component. Check fuse #18 (20 amp) in the PDC. It feeds fuse #13 (10amp) in the interior fuse box which feeds the IC. Check fuse #17 in the PDC. It is the IOD fuse; it feeds a number of circuits in the vehicle. Check all fuses with the ignition off or negative battery lead disconnected.

You can also try disconnecting the battery for several minutes and reconnecting it. If the reconnect doesn't help you will need to have the issue diagnosed. There are virtually no serviceable parts on the IC, so be prepared to purchase a replacement if necessary. They are not plug and play; each IC is vehicle specific and must be programmed.

Follow up from owner - Thank you for your response, it was the brake lamp switch switch.

 

1361. I just bought a previously owned 2002 TE PT with 38k miles last month.  I noticed a rough idle at traffic stops, though there's no hesitation or stalling.  Dealer checked it out and said there were no codes.  They changed the plugs, but said the existing plugs were fine.  If they did anything else, I wasn't told.  They told me that this rough idle was a common thing and that if I bought the car I'd just have to live with the rough idle.  I noticed in some of the Q&A's that folks had a PCM cleared.  What is the PCM and should I investigate or look at other components?  Your thoughts?  Thank you. – Stan, from North Carolina.

Varying degrees of rough idle have been reported by owners. According to DC, some rough idle is considered normal with the PT. Moderate to severe rough idle can be caused by other factors and can usually be diagnosed and treated. You should ensure the new plugs are gapped at .042, instead of .050, which was the prior specification before Chrysler issued the TSB asking for .042. I would install new (and better) plug wires. They have been the cause of many rough idle issues without triggering a misfire code. The PCM (Powertrain Control Module) is the main computer for the vehicle. DC has issued some TSB's which call for reprogramming or flashing the PCM to eliminate some drivability issues. TSB's are available for review in the Pit area on the site.

 

1362. I have a 2001 LE PT with 91k miles. While driving I hear wind noise, but until yesterday wasn't able to determine where it was coming from. While washing the PT I noticed water leaking into the driver side (quarter) window behind the rear passenger window. I noticed that the weather stripping has come off the upper corner of the window and I can actually see down into the window are fairly well. I would like to know how hard it would be to remove the outer stripping and replace the inner adhesive then replace the outer weather stripping. Thank you for your help. – Diana, from Texas.

The quarter window is part of the stationary glass in the vehicle, which also includes the windshield and backlite (liftgate) glass. From what I can determine in the SM and parts manuals, the weather seals are part of the quarter window assembly. (I would suggest verifying this with your local dealer.) The process to remove and replace the quarter window will require a fair amount of work. You must remove the C and D pillar upper trim panels, and lower quarter trim panel as necessary, to access the window. You might also check with the dealer to see if there is any type of sealant you can use to seal the leak in lieu of replacing the quarter window, which would be a much less expensive approach. You might also check with your local auto glass stores for additional ideas; they work with stationary glass on a variety of vehicles.

 

1363. I have a 2001 LE PT with 55k miles. The temperature operating range has been dead center for the last 50k miles. However, it recently changed to 1/2 of previous reading (lower) and mileage has dropped 2-3 mpg. The vehicle self tests indicate no faults. Thanks for your time. – Joe, from Florida.

It sounds like the thermostat is faulty. It's a non-PCM controlled mechanical device. It's opening too soon. I'd say that if you let it idle long enough with the fans off, it would reach the 210F needed to turn on the engine cooling low speed fan. There are guides in the Pit area that you can utilize if you plan to DIY.

Follow up from owner - Replaced the thermostat today and the temperature gauge returned to midrange, correct reading immediately. The DIY guide was also a big help.

 

1364. I have a 2001 BE PT with 33k miles and manual transmission. I experienced no trouble shifting during the summer months, but now with cooler weather, when I start the PT in the morning sometimes I cannot shift in into any gear. If I do get into gear then it is very hard to shift, or it just won't go into another gear. After about 15 minutes of hard shifting it shifts just fine. – Luis, from Texas.

The majority of PT owners we hear from have automatic transmissions therefore we haven't received much feedback on the 5-speed.

Hard shifting may be caused by a misadjusted crossover cable. If hard shifting is accompanied by gear clash, synchronizer clutch and stop rings or gear teeth may be worn or damaged. Misassembled synchronizer components also cause shifting problems. Incorrectly installed synchronizer sleeves, struts, or springs can cause shift problems.

In excessively cold climates temporary hard shifting may be the result of the temperature of cold transaxle fluid. When it's cold the consistency of the fluid is thick which would make the shifting process somewhat more difficult. As the vehicle warms up, the fluid becomes hot and thins which makes it easier to shift. That being said, the temperatures in San Antonio are not excessively cold right now, so I don't think this is the issue or normal behavior for the PT. Given the recent shift cable replacement, you may want to have the issue checked out by the dealer to make sure that everything is functioning correctly. Let us know how you make out.

 

1365. It has been suggested by my dealer to have my PT's power steering fluid flushed as a scheduled maintenance service. I have never heard of this being done before. Is there any good reason for it? Thanks. – Peter, from Canada.

Chrysler, along with many other car manufactures do not provide an interval change schedule for the power steering fluid, however they do list interval service checks for inspecting and adjusting the power steering pump belt tension, and the owners manual suggests a monthly power steering fluid level check. If you've read through the Steering subsection in the Technical Library and the Top Ten Issues Guide you'll notice that a number of owners have experienced problems with the PT's power steering system components. DC has issued three TSB's related to the fluid, and or correct fill method in order to avoid premature system failure, which can be reviewed on the site.

That being said, some do-it-yourselfers have chosen to change the steering fluid at the same time they change the engine coolant (60 months or 60k miles, which occurs first), or earlier, as a precautionary measure given its importance in the power steering system and the reported failures.

The function of this fluid is basic: transmitting hydraulic pressure to make steering easy. But achieving a seamless system operation over a wide variety of conditions is not. The fluid must perform consistently in any situation, from sub-zero to triple-digit temperatures, and both ambient and under-hood temperatures. It also must function when the engine is at idle or full-throttle, and under high pressure, all the while providing adequate lubrication to pump and control valve assemblies, maintaining integrity of rubber components in the system, and promoting noise-free system operation over an extensive period of time. These demands take their toll on the fluid and eventually break it down, which can lead to inconsistent performance and component failure.

Power steering systems can be very expensive to repair and are often the result of using the incorrect fluid, improper fluid level and or contamination. The fluid is the cheapest component of the power-steering system and changing it can help to prolong the life of other more expensive parts. If you've had work done on your power steering system, or the dealer inspected the fluid and noted debris (seals and internal components in the pump that wear out), dirty fluid or contamination they might recommend that you have it changed. Servicing involves draining or flushing out your car's old power-steering fluid and then adding fresh fluid. Keep in mind that Mopar ATF+4 (MS9602) is red in color and MS9933 is amber/yellow in color and should not be interchanged. These fluids will darken in color with usage and fluid color is no longer an indication of fluid condition. (Review your owners' manual to determine the correct fluid for your vehicle.)

 

1366. We have a 2003 TE PT with 28k miles. Our gas cap was swiped and I replaced it with an aftermarket cap, but now I'm seeing a lit malfunction light indicator on the instrument cluster. What could be causing this? – Gabriel, from Nevada.

The cap is part of the fuel system which is pressurized. When the vehicle is started the fuel system is checked. If the pressurization is out of specification the MIL will pop on. The cap you purchased may not be suitable for the PT, or perhaps it is too loose. Try tightening it, if that fails to help replace it with an OE fuel cap.

 

1367. I have a 2002 LE PT 30.5k miles. Once in awhile when backing the car out of the garage (cold) into the street I hear a clump when shifting from Reverse to Drive. It only does it (occasionally) in the morning when the engine is cold. Afterwards it's fine. This has been going on for about three months. Once I drive it away from the house it's O.K. – Marcel, from Nevada.

If you are shifting into drive with the PT still slowly rolling backwards, you are doing untold damage to the transmission. (I see this all the time from owners who don't even realize they do it.) Other than that, a general inspection of the powertrain, mounts, and suspension may find something wrong or loose.

 

1368. I have a 2001 LE PT with 70k miles. I bought a new replacement front fascia on Ebay after a small fender bender. When it arrived I noticed that it didn't have a lower grille, just a hole with mounting holes on each side. My 2001 has a one piece fascia. Was this just a model change thing or is this a crappy part? Is there some kind of lower grille I can buy? Thanks in advance. – Braxon, from Florida.

I checked the 2001-2004 model year part manuals and they're all the same. The lower grille is molded into OE front fascia assembly. It is not available as a separate item. You could cover the lower grille hole with an aftermarket grille kit. For example, the E&G Horizontal Grille includes aluminum upper and lower grille sections. You can find the appropriate installation guides and photos in the Pit area.

 

1369. I purchased a preowned 2001 LE PT with 17k miles. I had an accident and took the engine out so we could fix the frame. After the mechanic put everything together the engine started to idle excessively. About a week ago the engine stalled while I was a stop sign. It happened again twice this week. The self check indicated no fault. The vehicle has not had a tune up in 5 years. Thanks. – Abdhul, from New York.

When you pull an engine and reinstall you introduce a great number of potential variables which are not normally introduced when you diagnose a driveability issue on a preexisting engine installation. I'm afraid there's not enough information to suggest a specific cause to the excessive idle and stalling. The PCM adjusts engine idle speed through the idle air control motor to compensate for engine load, coolant temperature or barometric pressure changes. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations (brake, park/neutral, air conditioning).

Under the right conditions there are a number of components that can contribute to stalling issues including the coolant temperature sensor, faulty or corroded wiring connections, fuel injectors, MAP sensor, IAC Motor, throttle body sensor and oxygen sensor.

As you can see both issues could be related, or not and a number of components could be suspect. Although you didn't see any faults running the self tests, there are a large number of codes which can be recorded but won't show up unless you use a scan tool. I would suggest that you have the PT diagnostically checked with a scan tool to try and narrow down the issue.

Follow up from owner - Thanks for your advice, the PT stopped stalling after I had it scanned and replaced the throttle body sensor and downstream O2 oxygen sensor.

 

1370. I have a 2001 TE PT with 71k miles. I went to start the PT one day and it didn't turn over, so I assumed it to be the battery. I changed the battery and tried to start it and on the odometer it read 'no fuse'. The headlights work, but nothing else. Could you give me any ideas? – James, from Alabama.

If the instrument cluster does not detect voltage on the courtesy lamp circuit, the message "FUSE" will alternate with the odometer/trip odometer. The lack of voltage can be due to the M1 Fused B(+) (IOD) fuse being open, or a circuit problem. I would start by checking the IOD fuse in the PDC under the hood.

With respect to the battery, you replaced the battery under the assumption that it was bad, but did not indicate why, or if the remaining charging or starting systems were tested. The battery, starting, and charging systems in the vehicle operate with one another and must be tested as a complete system. In order for the engine to start and the battery to maintain its charge properly, all of the components that are used in these systems must perform within specifications. It is important that the battery, starting, and charging systems be thoroughly tested and inspected each time a battery needs to be charged or replaced. The cause of abnormal battery discharge, overcharging or early battery failure must be diagnosed and corrected before a battery is replaced and before a vehicle is returned to service. When attempting to diagnose any of these systems, it is important that you keep their interdependency in mind.

 

1371. We have a 2001 LE PT with 91k miles. The windshield reservoir pump is not working and the dealer wants $125 for labor. Where is the pump, and is it difficult to get at and replace? Thank you. – Jeff, from California.

The PT is equipped with an electrically operated windshield washer pump, which is mounted directly to the reservoir. The pump and reservoir are serviced as separate assemblies. The replacement procedure in not complex, but will take a little time to complete. Most DIY'ers with average skills can handle the task. You'll find an OE guide in the Pit area for this procedure.

 

1372. I have a 202 BE PT with 60k miles. I'm experiencing an intermittent starting issue. Occasionally, it won't start and there are no fault codes. I used a spark tester and there is no spark on any of the plug wires. Later it starts and runs ok. What causes this? Thanks. – Kathleen, from West Virginia.

No spark in any cylinder suggests a failing coil/module or crankshaft position sensor. If there's no spark and no injector activity, the problem is more likely to be the crankshaft position sensor. That said, the intermittent behavior also suggests a possible wiring issue. Ignition coil problems are often caused by loose, broken or corroded wiring terminals and connectors.

Follow up from owner – It was the crankshaft position sensor. Thanks.

 

1373. I have a 2001 LE PT with 53k miles. I have noticed a misfire under load with the A/C on or 3 or more people in the vehicle driving uphill. I'm not tripping any fault codes according to the self tests. I have replaced the plugs and wires; any guesses? – Doug, from Ohio.

When the OBD II system detects a misfire that exceeds "normal" limits, it sets a DTC that corresponds to the misfiring cylinder. If a DTC isn't set the problem you're experiencing either isn't a misfire, or not severe enough to trigger the DTC. Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load and or operating conditions. More often than not it's the plugs and or wires. If you have ruled them out I would check the fuel injectors, EGR valve and throttle body next.

Follow up from owner - I can feel the misfire and my snap on scanner indicates that the misfire is in cylinder #1, but still no fault code. I had the Champion DP's installed, swapped them for a regular set of Champions, and I still have the misfire. Not going to bother w/wires they're fairly new and pass the ohm's tests. I'm still thinking coil pack/module?

PT DIY follow up - I wouldn't rule out the new plugs. New plugs are occasionally faulty. Regardless of how the new the plugs are, I would still pull, inspect and replace the plug in the suspect cylinder to rule out that possibility. That should be fairly straightforward on cylinder 1 without removing the upper intake. If you have experienced any overheating issues check the compression on cylinder #1 when you pull the plug. Check the wire installation - loose fitting boots can cause misfire. If you still have the old ignition wires you may want to swap one out to rule out any issues there. The PT has two coil packs. Coil number one fires cylinders 1 and 4. Coil number two fires cylinders 2 and 3. If you have a failing ignition coil it would affect cylinder 1 and 4.

Follow up from owner – In all my years, and literally thousands of plugs, I've never been bent by champion like this one. Thanks for your help, plug #1 was faulty and the fuel injector cleaning seemed to do the trick.

 

1374. I have a 2002 PT and my father has a 2005. His seems to have a better turning radius; is a difference in the turning radius of the different years and model's? If there is a difference can it be changed? - Anonymous, from USA.

It has changed somewhat over the years, dependent mostly upon tire/rim and transaxle configurations. The PT's base tire is 15” and the Turbo utilizes a 17” tire.

1375. I have a 2001 LE PT with 72k miles. I need to put fuel injector cleaner into my car. I was told I could put a can in the gas tank and the other in a hose that would get it into the injectors better. I don't know how to do that. Can you help? Thanks a lot. – Angie, from North Carolina.
