Part Seventy Three Q&A 1801 - 1825

1801. I have a 2003 TE PT with 45k miles. I have seen "cabin air filters" in magazines. I would like to replace mine, but can not find where it is located. Is this something a non-mechanic can do? Thank you. – Fred, from Montana.

Cabin air filters were introduced on domestic PT's in 2003 however application seems to be sporadic. They can be found on some PT's and not on others. I suspect they were simply introduced during the middle of a model year hence PT's which were built early may not have them. Some owners have reported finding the housing in place minus the filter and other owners have reported that the housing was also absent. The housing and filter, or filter alone can be purchased (DC dealer parts department) and installed, which a number of owners have done. More information here and here.

The black OE filter housing is installed behind the window washer reservoir in the engine bay under the passenger side air intake cowl, located at the base of the windshield. I would suggest that you remove the cowl and check for the holder.

Prior to becoming available for the PT a few DIY filter installations were developed using aftermarket parts. There's a guide in the Pit area which describes this application as well as installation for DC's OE system.


1802. I have a 2005 LE PT. The PT will intermittently (suddenly) die on me, in particular at moderate speeds of approximately 35-45mph. One time when this happened I noticed that the speedometer dropped to zero, even though the car was still moving at about 30mph. I'm getting fault code P2097. – Richard, from the USA.

You'll notice that there are a number of possible causes for this fault. If you have some experience with automotive repair you may be able to check a few of these possibilities out on your own, however keep in mind that the diagnostics are written for trained auto technicians who also posses the necessary test equipment.

Given that this is an intermittent issue it may be somewhat difficult to accurately diagnose unless you can duplicate the issue. The dealer will experience the same difficultly troubleshooting the issue unless they can reproduce the problem at will. Regrettably, you may have to wait for the component in question to fail before you can obtain an accurate diagnosis.

P2097-Down Stream Fuel System 1/2 Rich

Possible Causes

Good Trip Equal to Zero
Exhaust Leak
Engine Mechanical Problem
O2 Sensor
O2 Signal Circuit
O2 Return Circuit
Fuel Contamination


1803. I have a 2006 TE PT with 35k miles. The rear wiper is not operational. I checked the owner manual and did not see a fuse associated with the rear wiper. Thanks. – Kevin, from Kentucky.

The Totally Integrated Power Module provides battery voltage and ground to operate the washer pump/motor unit and a control output to the rear wiper relay, which provides battery voltage to operate the rear wiper module. Rear wiper/washer system operation is completely controlled by the TIPM logic circuits, and that logic will only allow these systems to operate when the ignition switch is in the Accessory or On positions.

The most accurate means to diagnose the right multi-function switch or the TIPM inputs and outputs related to the various rear wiper and washer system operating modes requires the use of a DRB III scan tool and diagnostic manual. Your vehicle appears to be under warranty, see your local dealer for assistance.


1804. I purchased a pre-owned 2004 TE PT with 71k miles about a month ago. A week after purchasing it, it started to idle hard every once in a while. Then idle rpm would fluctuate; fall below 1 and come back up. Then after that my oil pressure light would come on and off until I accelerated again. Then as soon as I stopped it would come back on. So I took it back to the dealership and they replaced the switch so the light doesn't come back on, but it still idles hard and the rpm's still go down instead of up when it does that. What should I do? – Joshua, from N.C.

The IAC motor (inside the throttle body) controls idle using a variety of inputs through the PCM. In this instance rough idle or stalling occurs when the idle speed drops below normal rpm. This can be caused by an issue with any one of the inputs which control idle through the PCM or a problem with the IAC motor. If your vehicle is still under warranty with the dealer let them diagnose and make the repair. If not and you wish to DIY you can try, but it may be hit or miss without diagnostic equipment. There are only a few things you can check. First, clean the throttle body where the IAC motor resides. Sometimes the pintle on the motor will hang up in a dirty TB. If that doesn't help, next check the condition and gap on all the plugs. Change if necessary and check for effect. See Tech Library, OEM Engine Performance and Ignition Control subsections.


1805. I have a 2002 TE PT with 120k miles. Will burning 10% Ethanol or any percentage of Ethanol harm any part of the OE fuel system? Several years ago I burned 10% Methane in our fuel injected car and I had to replace the injectors, the fuel pump and all the rubber sections of the fuel system. – Ed, from Maryland.

The owners' manual states: “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. It has been reported that the use of Ethanol will result in a slight reduction in MPG however this information hasn't been confirmed.

E85=85% ethanol and 15% gasoline.
E10=10% ethanol and 90% gasoline.


1806. We have a 2006 LE PT with 15k miles. When the low fuel indicator lamp comes on how much fuel is left in the tank? – Melisa, from Connecticut.

Approximately two gallons remain.


1807. I have a pre-owned 2001 LE PT with 95k miles. I went to do an oil change and found that the previous owner or shop had completely rounded the drain plug bolt off. I wondered if you had any ideas as how to remove it as I have tried to no avail. Thanks. – Paul, from Australia.

If the bolt head is completely stripped you could try using an Easy-Out bolt and screw extractor, or a left-handed drill bit. Easy-Out's can provide mixed results therefore using a left-handed drill bit might be more productive if the bolt isn't too tight. Be careful that you don't strip the threads in the oil pan itself, which will create a new set of problems (oil leak, re-tap threads, addition of a heli-coil or possible pan replacement). Spray the bolt with penetrating oil and let it soak awhile to help loosen it prior to attempting removal. Heat can also be helpful, but be very careful of the source and how you apply it. Try conducting a Google search for the additional alternatives, or you can have your local dealer handle it for you.

Follow up from owner - I used a left handed drill bit and it came straight out. Thanks again for your help.


1808. I have a 2007 TE PT with 23k miles. Yesterday I noticed that the engine light came on after a fill up. What could be causing this? Thanks. – Aaron, from Montana.

The first thing I would check is the gas cap; make sure that the cap is tightened at least 1/4 turn until you hear one or more clicks. This is an indication that cap is properly tightened. If the gas cap is not tightened properly, the malfunction indicator light will come on.

On late model PT's (2006 and later) if the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “gASCAP” message will be displayed in the odometer/trip odometer in the instrument cluster. Tighten the fuel filler cap properly and press the odometer/trip odometer reset button to turn the message off. If the problem continues, the message will appear the next time the vehicle is started.


1809. We have a 2005 GT (HO) convertible with 21k miles. While going up some long hills the cruise cuts out (more then once this has happened) and the Malfunction Indicator lamp came on. Dealer checked said it was code P2074 and that there wasn't a problem he just reset it. The vehicle idles rough. We drove the car through the Rockies last weekend and on long or steep hills it would cut out at about 2500 rpm. When it did cut out I would stop, which is when we had a very rough idle. Restarting the car seemed to clear the problem. After a few occurrences I put it into select shift and down shifted on hills to third, this stopped the problem. Thanks. – Don, from Canada.

P2074-Manifold Pressure/Throttle Position Correlation - High Flow/Vacuum Leak

Possible causes:
Good Trip Equal to Zero
Vacuum Leak
High Resistance in Map (K7) 5 Volt Supply Circuit
Resistance to Ground In Map (K7) 5 Volt Supply Circuit
MAP Sensor
High Resistance in (K1) Map Signal Circuit
Resistance to Ground in (K1) Map Signal Circuit
High Resistance in (K4) Map Ground Circuit
TP Sensor Operation
High Resistance in (K7) TP Sensor 5 Volt Supply Circuit
Resistance to Ground In (K7) TP Sensor 5 Volt Supply Circuit
TP Sensor
High Resistance in (K22) TP Signal Circuit
Resistance to Ground in (K22) TP Sensor Signal Circuit
High Resistance in TP (K4) Sensor Ground Circuit

As you can see there are a number of possible issues which can cause this DTC. You may be able to visually check a few things (vacuum) on your own however the majority of tests require the use of a DRB III scan tool, diagnostic manual and other test equipment. Based upon your description I would lean towards a vacuum related issue.

1. Inspect the Intake Manifold for leaks and cracks.
2. Inspect the Power Brake Booster for any vacuum leaks.
3. Inspect the PCV system for proper operation or any vacuum leaks.


1810. I have a 2003 BE PT with 64k miles. I went to a small garage and they told me that I need to get an O2 sensor. The check engine light is on and the fault codes are P0138, P0038 and P0340. Any input will be helpful. Thank you. – EJ, from Canada.

A Diagnostic Trouble Code indicates that the Powertrain Control Module 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.

P0038 -O2 sensor 1/2 Heater Circuit - Shorted condition detected in the oxygen sensor heater element control feedback sense circuit. See Tech Library, Electronic Control Modules subsection for more information.

P0340 -Camshaft Position Sensor Circuit - A rationality error has been detected for loss of camshaft position sensor. See Tech Library, Electronic Control Modules subsection for more information.

The P0138 DTC is listed for the 1.6L engine only in all of our diagnostics manuals. There's no listing for the DTC under the 2.4L engine. Therefore the possible cause information below refers to the 1.6L engine.

P0138 -1/2 O2 Sensor Shorted To Voltage - Oxygen sensor input voltage maintained above normal operating range.

Possible causes:

Intermittent Condition
O2 Sensor Operation
O2 Sensor Signal Shorted To Voltage
O2 Sensor Signal Open
O2 Sensor Ground Circuit Open

1/2= O2 sensor before the cat.
2/2= O2 sensor after the cat.

There are a number of potential causes for these DTC's some of which may be related however further troubleshooting will be required to isolate the issue(s). Our advice is to see your local dealer; they're simply more familiar with the vehicle than the services an independent repair shop offers.


1811. I have a 2005 TE GT (HO) convertible with 64k miles. The deck will not open by the remote or from the glove box release. – Jimmy, from Idaho.

Possible Causes include:

Decklid Release Switch Open
Decklid Release Switch Sense Circuit Open
Remote Keyless Entry Module Open
Solenoid Ground Open
Decklid Release Solenoid Open
Decklid Release Relay Output Wire Open
Rke Module - Decklid Relay Open

This issue will require dealer assistance to resolve.


1812. I have a 2005 TE PT with 80k miles. I can't remove the passenger side rear seat. The release cable seems to be broken. I can't get the seat unlatched to replace the cable. It's so tight I can't even get a putty knife or anything under it to release the hook part. Has anyone else out there had the same problem? Thanks. – Craig, from Washington.

Yes, a few owners have reported issues of this kind. It's discussed in the owners' manual. You can try their fix, but at least two owners that we know about ended up at the dealership for resolution.

Warning - The rear center lap/shoulder belt is equipped with a lock-out feature to ensure that the rear seat back is in the fully upright and locked position when occupied. If the rear seat back is not fully upright and locked and the rear center lap/shoulder belt can be pulled out of the retractor, the vehicle should immediately be taken to your dealer for service. Failure to follow this warning could result in serious or fatal injury.

Rear Center Lap/Shoulder Belt Retractor Lock-Out

This feature is designed to lock the retractor whenever the rear seat back is not fully latched. This prevents someone from wearing the rear center lap/shoulder belt when the rear seat back is not fully latched.

Note - If the rear center lap/shoulder belt can not be pulled out, check that the rear seat back is fully latched.

If the rear seat back is properly latched and the rear center lap/shoulder belt still can not be pulled out, the Automatic-Locking Retractor (ALR) system may be activated. To reset this feature you must let all of the belt webbing return into the retractor. You will not be able to pull out more webbing until all of the webbing has been returned back into the retractor.


1813. I have a 2005 BE PT with 42k miles. The engine light came on, and I promptly took it to a mechanic who diagnosed O2 sensor failure. Both sensors were bad, and a solvent was flushed through the fuel line (but fuel filter was not replaced). Since then, the engine has sounded different. When starting the engine, it will lose power when going up a hill or accelerating onto a road. Once the car is running for a while, this stops. If I turn the engine on and let it idle, the engine seems to vibrate excessively. It even quit once after a few minutes, but started right up again when I reengaged the ignition. I have been in contact with the service shop who handled the repair and they are willing to look at it, but I am dubious of their diagnosis, as the car ran fine before I brought it in two days ago. Could they have neglected something? Thank you. – Suzanne, from Maryland.

As indicated below, the symptoms that you describe can be caused by a variety of issues however during the fuel line cleaning, if plugs were fouled, or if the fuel line is clogged, or there's residual solvent in the system which has mixed with the gas, this may also explain the symptoms. Unless you were experiencing a drivability issue I can't think of a reason why it was necessary to clean the fuel lines on a vehicle with 42k miles. (The fuel filter is not a serviceable part on the PT.) In addition, incorrect O2 sensors could also cause the symptoms you describe.

Engine misses on acceleration and or loss of power can be caused by a variety of issues:

1. Dirty or incorrectly gapped spark plugs.
2. Contamination in Fuel System.
3. Burned, warped, or pitted valves.
4. Faulty ignition coil(s).
5. Faulty fuel pump.
6. Incorrect valve timing.
7. Leaking cylinder head gasket.
8. Low compression.
9. Plugged or restricted exhaust system.

Follow up from owner - When I took the car back, they rechecked and said the new O2 sensors were shot, and they would have to replace them with Chrysler sensors. Now that the correct sensors are installed, the car is up and running! Thank you for the help.


1814. I have a 2005 LE PT with 47k miles. When using the turn signals this evening I noticed the right indicator on the dash blinked, but the left did not. What would cause that? Thank you. – Janet, from Florida.

If either indicator remains on and does not flash, or there is a very fast flash rate, check for a defective outside turn signal bulb. If an indicator fails to light when the lever is moved that would suggest that the fuse or indicator bulb is defective.


1815. I have a 2001 BE PT with 104k miles. The radiator fan never runs, and fuses are fine. There are two hoses connected to the coolant reservoir. The one connected to the radiator is fine but the second is not connected to anything; where is it supposed to go? – Mike, from Florida.

The coolant recovery system consists of a coolant recovery container mounted to the dash panel. The hose on the left connects the recovery container to the coolant outlet connector on the engine and a pressure cap. The one on the right is a vent hose. It normally clips to a stud on the dash panel.

There's not enough information to suggest a specific cause for the inoperable radiator fan. If this condition exists “Radiator Fan Will Not Operate, Gauge Reading High or Hot” possible causes include:

1. Fan motor defective.
2. Fan relay, powertrain control module (PCM) or engine coolant temperature sensor defective.

3. Blown fuse in power distribution center (PDC).

The radiator fan/module is a common fault. A number have failed and been replaced by owners. Fan operation is controlled by a variety of PCM inputs and can be tested under all operating parameters by your local dealer. See Tech Library, Cooling subsection.


1816. We have a 2001 LE PT with 70k miles. The power steering fluid is leaking from somewhere and I do not know how to locate it. Any help would be appreciated. Thanks much. – Dave, from Florida.

OE guides are available through the Pit area on the site however I would suggest that you have it professionally checked given the issues a number of owners have encountered with the power steering system over early model year PT's.

You can visually check for leaks at (loose) power steering hose fittings, but almost anything else that you encounter (Damaged fitting, seal, gasket, O-rings, or power steering pump or gear leakage) will require dealer intervention. See Tech Library, Steering subsection.


1817. We have a 2006 LE PT with 17k miles. The seat belt chime is driving us crazy; is there a way to shut it off? - Ray, from Pennsylvania.

The easiest and recommended way to silence the chime is to use the seat belts as intended, as a safety device and component of the restraint system.

The Enhanced Seat Belt Reminder System will activate if the driver's or front passenger's seat belt has not been buckled within 60 seconds of starting the vehicle. It will also activate if vehicle speed is greater than 5 mph (8 km/h) to alert the driver or front passenger to buckle their seat belt. (The driver should also instruct all other occupants to buckle their seat belts.)

Once the warning is triggered, the ESBR System will continue to chime and flash the Seat Belt Warning Light for 96 seconds or until the driver's or front passenger's seat belt is buckled. The ESBR System will be reactivated if the driver's or front passenger's seat belt is unbuckled for more than 10 seconds and vehicle speed is greater than 5 mph (8 km/h).

The ESBR System can be enabled or disabled by your authorized dealer or by following these steps:

Note - The following steps must occur within the first 60 seconds of the ignition switch being turned to the ON or START position. DaimlerChrysler does not recommend deactivating the Enhanced Warning System.

1. Turn the ignition switch to the LOCK position and buckle the driver's seat belt.

2. Turn the ignition switch to the ON position and wait for the Seat Belt Warning Light to turn off.

3. Within 60 seconds of turning the ignition switch to the ON position, unbuckle and then re-buckle the driver's seat belt at least three times within 10 seconds, ending with the seat belt buckled.

Note - Watch for the Seat Belt Warning Light to turn on while unbuckling and off while re-buckling the seat belt. It may be necessary to retract the seat belt.

4. Turn the ignition switch to the LOCK position. A single chime will sound to signify that you have successfully completed the programming.

The Enhanced Warning System can be reactivated by repeating this procedure.

Note - Although the Enhanced Warning System has been deactivated, the Seat Belt Warning Light will continue to illuminate while the driver's or front passenger's seat belt remains unbuckled.


1818. I have a 2002 LE PT with 34k miles and auto transaxle. The transmission slips and the PT won't move. It just started on the way to work this morning. I had to let it idle for 30 to 60 seconds in order for it to propel my car again. Then it worked for about 60 to 90 seconds and slipped again. The self test indicated DTC P0846. Can I change the fluid sensor switch myself? Where is it located? – Raymond, from Florida.

DTC's are the result of a system or circuit failure but do not always directly identify the failed component or components.

P0846 - 2/4 Pressure Switch Sense Circuit

Possible Causes
2/4 Pressure Switch Sense Circuit Open
Transmission Control Relay Output Circuit Open
2/4 Pressure Switch Sense Circuit Short To Ground
2/4 Pressure Switch Sense Circuit Short To Voltage
2/4 Pressure Switch
Powertrain Control Module
Intermittent Wiring and Connectors

The Solenoid/Pressure Switch Assembly is external to the transaxle and mounted to the transaxle case. Several owners have reported replacing the solenoid pack. If you don't have access to service manual the procedure is available through the Pit area on the site.


1819. I have a 2002 DC PT with 91k miles. After the radiator was replaced I experienced hard starting, which I have never experienced before. As a result I had the plugs and wires changed and added some fuel injector cleaner. This did not help and a few days after the replacement it would not even turn over. It did however start several hours later for my husband, although still a hard start. The following day, the check engine light came on and I took it to have the code read, I was informed that it was misfiring on several cylinders. It is running rough at idle (I assume from the misfiring), but seems normal when in motion. I had a friend who is a mechanic look at it and he is perplexed as well. After checking everything he cleared the codes and ran the test again. A new code indicates that it's running too rich. We would really appreciate any insight you may have. Thanks. – Jessica, from Indiana.

I'm afraid there's not enough information here to suggest a specific cause for the issues you're experiencing all of which can be caused by a variety of factors.

Hard starting can be caused by:

1. Dirty fuel injectors. Would require professional cleaning; the over the counter stuff you dump in the fuel tank is ok for maintaining a working fuel system, but if you already have dirty injectors it's usually not sufficient to remedy the problem.

2. Fuel pressure (Low fuel pressure means a lean fuel mixture and high pressure results in a rich condition.)

3. Insufficient engine crank speed. A low crank speed can be caused by a weak battery, loose or corroded connections, dragging starter motor, etc.

4. Weak ignition spark can be caused by a faulty crank sensor, ignition coil or leaking secondary ignition cables.

5. Idle air control. Hard starting, long crank time and stall after start may be the result of a sticking, binding or defective IAC motor. This can also result in low idle, rough idle and stall conditions. Cleaning the throttle body where the IAC motor pintle resides can sometimes resolve this issue. In some instances the IAC motor may have to be replaced. See misfires below.

6. MAP sensor. Can starve the engine for fuel or wash the cylinders down with a rich mixture. A troubled sensor may result in a surge, stall, no-start condition, or stall after start.

In many instances misfires are caused by faulty plugs, wires and dirty fuel injectors, however there are a number of other factors that can also cause it. See Tech Library, Electronic Control Modules subsection, P0300-P0304 Misfires.

If the engine runs rough when idling, and smooth while in motion, idle is controlled by a variety of sensor inputs through the PCM. See Tech Library, OEM Engine Performance subsection, idle issues.

The best advice we can offer is to have your local dealer take a look. They are more familiar with the vehicle than most independent repair shops and would have a better shot at identifying the issue.


1820. We have a 2002 TE PT with 39k miles. Our horn no longer works. Where is fuse located? Thank you. – Nancy, from Connecticut.

Horn does not sound. Possible causes include:

1. Fuse - Check fuse #14 (15 amp) in the PDC under the hood.
2. No voltage at horn relay terminals 62 & 66 and fuse is ok.
3. Open circuit from terminal 65 of the relay to horn switch X3 circuit.
4. Faulty or damaged horn.
5. Faulty horn switch.

Follow up from owner – It was the fuse. Thanks.


1821. I have a 2003 BE PT with 66k miles. My dome light and cigarette lighter have both stopped working. I've checked all of the fuses and nothing seems to be bad. Could these two things be related? The A/C was repaired around the same time they both stopped working. Could this have anything to do with it? – Nicole, from Florida.

It's not likely; they're on different circuits. The cigar lighter is fed through the ignition switch by fuse #20 (20 amp) in the PDC under the hood. The dome lamp is controlled by the cluster and fed by fuse #13 (10 amp) in the interior fuse box.

If the fuses are ok, check the dome lamp to make sure it hasn't burnt out and dimmer control on the stalk to make sure it isn't in the OFF position. If both are ok, your local dealer will have to assist.


1822. We have a 2005 LE PT convertible with 33k miles. My husband read something about a device being installed in vehicles to record accident information. Does our PT have this device? Thank you. - Amanda & Larry, from Iowa.

The device is called an EDR or Event Data Recorder. Chrysler began installing the EDR on domestic PT's beginning with the 2006 model year.

In the event of an airbag deployment, each vehicle is designed to record up to 2-seconds of specific vehicle data parameters in an event data recorder prior to the moment of airbag deployment. Such data are ONLY recorded if an airbag deploys, and are otherwise unavailable.

In conjunction with other data gathered during a complete accident investigation, the electronic data may be used by DC and others to learn more about the possible causes of crashes and associated injuries in order to assess and improve vehicle performance. In addition to crash investigations initiated by DC, such investigations may be requested by customers, insurance carriers, government officials, and professional crash researchers, such as those associated with universities, and with hospital and insurance organizations.

In the event that an investigation is undertaken by DC (regardless of initiative), the company or its designated representative will first obtain permission of the appropriate custodial entity for the vehicle (usually the vehicle owner or lessee) before accessing the electronic data stored, unless ordered to download data by a court with legal jurisdiction (i.e., pursuant to a warrant). A copy of the data will be provided to the custodial entity upon request.

General data that does not identify particular vehicles or crashes may be released for incorporation in aggregate crash databases, such as those maintained by the US government and various states.

Data of a potentially sensitive nature, such as would identify a particular driver, vehicle, or crash, will be treated confidentially. Confidential data will not be disclosed by DC to any third party except when:

1. When used for research purposes, such as to match data with a particular crash record in an aggregate database, provided confidentiality of personal data is thereafter preserved.

2. When used in defense of litigation involving a DC product.

3. When requested by the police under a legal warrant or otherwise required by law.

Data Parameters that May Be Recorded:

Diagnostic trouble code(s) and warning lamp status for electronically-controlled safety systems, including:

1. Airbag system
2. Airbag disable lamp status (if equipped)
3. Time of airbag deployment (in terms of ignition cycles and vehicle mileage)
4. Airbag deployment level (if applicable)
5. Seatbelt status
6. Brake status (service and parking brakes)
7. Accelerator status (including vehicle speed)
8. Engine control status (including engine speed)
9. Cruise control status
10. Traction/stability control status


1823. I have a 2003 GT PT with 35.5k miles. The mirror control will not cause the mirrors to move down or in. It is the same whether switched to left or right mirror. There are no other problems with switches. Thanks for your help. – Jerry, from Kansas.

The mirrors are controlled by a single switch assembly located on the front left lower instrument panel. The push button switch uses L (left) and R (right) for mirror selection and a button to push for the desired direction of mirror movement. The motors which operate the mirrors are part of the mirror assembly and cannot be replaced separately. Given that the issue affects both the left and right mirror it is unlikely that both mirror motors have failed simultaneously. It is more likely that you have a faulty switch. Diagnostics for the switch and motor, along with the replacement procedure are available in the service manual or through the Pit area on the site.


1824. I have a 2001 LE PT with 50k miles. I've been having an intermittent high-idle problem for a while now. I replaced the plugs, wires, various sensors, and other stuff recently, but while looking under the hood today I noticed something. A center bolt that holds down the head cover on the left side had a good collection of fresh oil around it, about 1/2" deep. I cleaned out the oil and then started the engine. Then I sprayed some MAP sensor cleaner at the bolt and it bubbled all around the bolt. I decided to tighten it down a bit and turned it about 1/8 of a turn with VERY light pressure. As it turned VERY easily, the bolt snapped. I took my ratchet out and the majority of the bolt came with it. When looking down the hole I can see a small part of the bolt still threaded. Then with the engine running I sprayed cleaner around the head cover and it bubbles like mad! What should I do? The idle is very high now around 1600rpm and unsteady. – Jeremy, from Washington.

Without access to the vehicle I can only speculate however I think you just discovered the cause of your initial idle issue. The bubbles that you see which are accompanied by a high and or rolling rpm are an indication of a vacuum leak. Removing the headless bolt is the next step. This may require the services of a professional or if you intend to DIY you may want to review this information.


1825. I have a 2001 LE PT with 70k miles. The vehicle will not start when ignition key is turned to start position. Instrument panel lights function and battery is o.k. I tried moving transmission shift selector back and forth from park to neutral but starter will not engage. Vehicle was towed to garage for further troubleshooting. Technician noted that the fuse in the ASD was blown; when a new fuse was installed it blew immediately which seems to indicate a short somewhere within the system. He contacted the local Chrysler dealership but they were not very helpful or interested in providing any trouble shooting assistance. Any suggestions on resolving this problem would be greatly appreciated. – Bill, from North Carolina.

The ASD sense circuit informs the PCM when the ASD relay energizes. A 12v signal at this input indicates to the PCM that the ASD has been activated. When energized, the ASD relay provides power to operate the injectors, ignition coil, generator field, O2 sensor heaters (both upstream and downstream), EGR solenoid and also provides a sense circuit to the PCM for diagnostic purposes. If the PCM does not receive 12 volts from this input after grounding the ASD relay, it sets a DTC.

If the fuse for the ASD circuit continues to blow the circuit will have to be troubleshooted to isolate the cause. If you have experience in this area, as a pit pass subscriber, we can provide you with the wiring schematics. Otherwise, we would suggest having your local dealer handle the diagnosis. If you want to conduct some basic DIY you can check for the obvious by visually inspecting the starter relay for indications of physical damage and loose or corroded wire harness connections.

Follow up from owner – Thank you for the wiring schematics. I decided to take the PT to a repair shop where my friend and fellow PT'er used to be the service manager. He was confident they could find the problem and they did. The issue and an oil change came to just over $500 of which 80% was labor for troubleshooting. The vehicle would not start even though lights, enunciator warnings, etc. would work with key in ignition switch. When the key was turned to the start position the starter would not engage; no relay chatter, clicking, or any sounds of any kind, dead quite. Found fuse #13 (20amp) in the PDC blown. They traced it to circuit A14 which was shorted to ground. No Input to ASD circuit; E4 traced to circuit 16 at ALDL. Checked and repaired short and replaced ALDL connector. Retested all systems and reinstalled steering column cover. Hopefully this information may help another owner if they encounter this starting problem!
