Part Sixty Seven Q&A 1651 - 1675

1651. I have a 2001 LE PT with 88k miles. The car has been fine for the last 50k I have owned it. Last week the air bag light came on while I was driving it. It will stay on for a minute or two, and then turn off. The cycling continues intermittently. I took it to the dealer and they charged me $50 for a diagnostics check to tell me there was nothing wrong with it (no error codes) and they couldn't replicate the problem. I easily replicated the problem within 2 minutes of starting up the vehicle in their parking lot. He was baffled and said he'd have to check with Chrysler's troubleshooting guide and get back to me. Perhaps they couldn't replicate it because it doesn't come on if the door is open and/or the seat belt is not fastened. He said at that point, there could be multiple points that could have a loose connection (seat belts, airbag sensors, etc). I'm stumped and I can't find much information online about this happening to other people. Any ideas as to what it might be? I'm going to check with other Chrysler dealers within an hour's drive to see if they know as well. Thanks in advance! – Tim, from Vermont.

The airbag system is generally very reliable. We have only received a few reports of this type from owners during the past seven years. Unfortunately, the majority of owners who request help through this service don't follow up after the problem the resolved. This makes troubleshooting (with any certainty) for additional owners with similar issues, difficult. Intermittent issues are usually related to wiring, loose connectors, corrosion, poor grounds and partially failing components within a system.

A warning indicator lamp usually indicates that a fault code is present. Airbag diagnostic trouble codes consist of active and stored codes. It's interesting that they haven't discovered ANY codes when they run a diagnostic. If the lamp popped on and conditions were met a stored code would be present to aid in troubleshooting.

Active Codes

The code becomes active as soon as the malfunction is detected or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction or has occurred in that ignition cycle. This means that the malfunction is currently there every time the control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected or not present in the subsequent ignition cycle. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present.

Stored Codes

Airbag codes are automatically stored in the ACM's memory as soon as the malfunction is detected. A ''stored'' code indicates there was an active code present at some time. However, the code currently may not be present as an active code. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. If a malfunction is not active while performing a diagnostic test, the active code diagnostic test will not locate the source or the condition. In this case, the stored code can indicate an area to inspect.

The diagnostic provides the following information with regard to intermittent issues within this area. The following procedure may uncover a malfunction that is difficult to locate within the restraint system:

If no obvious problems are found:

Erase the stored codes
Place the ignition in the Run position
Wiggle the wire harness and connectors
Rotate the steering wheel from stop to stop

In addition, there is a test to rule out problems with the cluster, which is not part of the airbag system, however based upon you've description I don't think it is cluster related.

Unfortunately, this is one problem you must resolve as soon as possible given that the system may not be operational when you need it and or could inadvertently arm/ignite during a normal driving cycle. Your dealer can contact DC STAR support for help if they can't resolve the issue. You may also want to consider obtaining a second opinion with another dealership.

 

1652. I have a 2005 TE GT Convertible with 30k miles. I purchased a set of aftermarket wheels that are 17 x 7 with a 40mm offset and a 5x100mm and a 5 x108mm lug patterns. I have the painted factory aluminum wheels on there now. I removed one of the front wheels today to test fit the new wheels and tires, and they would not fit the bolt pattern. Everything I have found on PT's says they only have 5x100mm lug patterns. Mine appear to be different, like 5x95mm. What models have the different pattern, if so? Any help you can provide would be appreciated. – Jerry, from Georgia.

Here's the information we have:

OE Tire/Wheel Sizes and Specifications

15" Stamped Steel Wheel
Diameter 15.0 inches
Width 6.0 inches
Bolt Pattern 5 x 100mm
Wheel Offset 36.5mm
Tire P195/65R15 Goodyear Eagle LS Radials
Revolutions per Mile 835

16" Cast Aluminum Wheel

It should be easy enough to verify with any pro tire shop or DC dealer. Check with the pro tire shop on available solutions for your issue.

 

1653. I have a 2002 LE PT with 64k miles. The headlight lens looks like the coating is wearing off at the upper portions, or becoming cloudy. Thought I'd seen this addressed on your excellent website before, but if so, I can't find it now. Thanks for the service you are providing PT owners. – William, from Texas.

We had one other owner write in about this issue a while back, however in his situation it turned out to be moisture related. DC issued a TSB about this back in August 2005, where they indicated some moisture is normal inside the headlamp unit and will appear as a cloudy or foggy condition inside the assembly. This moisture may be removed by activating the headlamps on high beam for 15 minutes. If water droplets larger than 1 mm in size have accumulated on the inside of the headlamp lens, the headlamp assembly should be replaced. The TSB is available in the Pit area on the site.

ollow up from owner - I appreciate the answer, but it didn't seem to fit my problem. It's taken a year to solve, but the local Cadillac dealer just fixed it (same problem with Cadillac's too). They sanded the headlight lens with very fine sandpaper which removed the cloudiness, then to remove the sanding marks they polished them out with a fine polishing compound and a high rpm pneumatic tool. They charge $100.

 

1654. I have a 2001 LE PT with 135k miles. I have a problem with my horn. It does not function when I tap the steering wheel. The horn does work when using the keyless entry system. Every once in a while the horn will toot, but lately more often not. Any SWAG about how to go about fixing it? – Roy, from Virginia.

It sounds like the switch. Try turning the steering wheel and operating the horn. If it functions intermittently while turning it is could be a short in the relay control wiring circuit inside the steering wheel, pinched horn switch wire under the driver airbag module, or defective horn switch. The switch is molded into the driver airbag Cover. When the driver airbag Cover is pressed, the horn switch makes contact to ground. The ground signal is carried to the horn relay and the horn sounds. The horn switch grounds to the airbag housing. If the switch is faulty the driver airbag module must be replaced. We strongly advise professional service when dealing with the restraint system.

 

1655. I have a 2006 TE PT with 8k miles. The turn indicator warning chime stopped functioning, washer fluid low warning failed to come on and seat belt warning chime stopped functioning. - Robert, from California.

These features are controlled by the chime software located within, and serviced with the instrument cluster. See your dealer; the vehicle is under warranty.

 

1656. I have a 2002 PT. My overhead (compass/temperature) console recently stopped working. Could there be a short somewhere? – Forum poster, from USA.

Check fuse #14 (20amp) and #13 (10amp) in the interior fuse box. If the fuses are ok, and the overhead console is still inoperative, other possible causes are:  

Fused Ignition Switch Output Circuit Open
CTM Ground Circuit Open
Compass/Temperature Module

 

1657. I have a 2002 2.0L export PT with 90k miles. All of the interior lights in my PT are permanently on. I have ensured all doors are firmly shut and left the car for at least 15 minutes and the lights are still on. I then went into the car and pushed the upper console push light switches and again left the car for 15 minutes, but the lights were still on. The only way I can get them off is to remove fuse #13. Do you have any experience of this problem? The car had also just completed its annual MOT test. Thanking you for you help. – Andrew, from the UK.

No, we haven't received any reports of this issue. Regrettably, in the US we don't get any exposure to the exports unless an overseas owner brings it to our attention. Possible causes for the courtesy lamps being on at all times include:

Courtesy Lamp Driver Shorted
Drivers Door Ajar Switch
Drivers Door Ajar Switch Sense Wire Short To Ground
Remote Keyless Entry Module - If Equipped
Instrument Cluster
Liftgate Ajar Switch
Remote Keyless Entry Module
Liftgate Ajar Switch Sense Circuit Short To Ground
Instrument Cluster
Panel Lamps Dimmer Signal Circuit Short To Ground
Multifunction Switch

Troubleshooting these components will require a DRB III scan tool. The multifunction switch and Remote Keyless Entry module are components which have failed frequently in domestic PT's however the symptoms that you describe are not similar to other reported failures of these components.

I would suggest that you try resetting the IOD fuse in the PDC. It controls a number of circuits in the vehicle including the cluster. Review all IOD fuse Q&A's in the Tech Library, Wiring subsection before proceeding. If that doesn't resolve the issue your local dealer will have to troubleshoot it for you.

 

1658. I have a 2001 LE PT with 14ok miles. Prior to the current issue (about 2 months ago) I changed the plugs, wires and ignition control. This seemed to stop all the problems we had at that time. Yesterday while driving at 40mph in the city, the car seemed to lose all of its get up and go. It just lost power all of a sudden; I thought we were going to stall right in the middle of traffic. I pressed the gas pedal to the floor and kept it there. Eventually the car seemed to respond. When we stopped at a traffic light it seemed to run a little rough, but later that also smoothed out. The same loss of power happened again later that night and my wife experienced the same problem the next day on her way to work. We stopped at Auto Zone and had them check the codes which were P0351, P0401, P0300 and P0420. – Ronald, from Missouri.

I suspect that at least two faults are related. For example, a P0300 and P0351 DTC can be caused by an EGR issue (P0401). Additional troubleshooting with a DRB scan tool and diagnostic manual will be necessary to make a determination.

P0401 - EGR System Failure - Required change in air/fuel ration not detected during diagnostic test.

P0300 - Multiple Cylinder Misfire

P0351 - Ignition Coil Primary # 1 Circuit - Peak primary circuit current not achieved with maximum dwell time. Possible causes include:

Ignition Coil
ASD Relay Output Circuit
Ignition Coil Driver Circuit Open
Coil Control Circuit Shorted To Ground
PCM

P0420 - 1/1 Catalytic Converter Efficiency - Catalyst 1/1 efficiency below required level. (This fault can also occur when you have a new upstream 02 sensor and a aging downstream sensor.)

Additional troubleshooting will be required to isolate the issue.

 

1659. I have a 2002 LE PT with 45k miles. About a month ago the MIL popped on with fault code P0133. After half a dozen start and stop cycles the MIL extinguished itself. A few days ago the MIL popped on again, with fault code P0134. I've driven a few drive cycles but the MIL has not extinguished itself. What would cause this DTC? Thank you. – Carl, from Wisconsin.

P0133 - 1/1 O2 Sensor Slow Response - Oxygen sensor response slower than minimum required switching frequency.

P0134 - 1/1 O2 Sensor Stays at Center - Neither rich, or lean condition is detected from the oxygen sensor input.

Both faults are related to the upstream oxygen sensor. Possible causes would include:

Exhaust Leak
O2 Signal Circuit
O2 Return Circuit
O2 Sensor

To some extent you can visually check for an exhaust leak, however given that you have experienced both fault codes I would suggest that it is probably not an issue with the exhaust or circuit, but a slowly failing sensor. Your local dealer will be able to test the system and make an accurate determination.

Follow up from owner - I decided to take a chance and replace the sensor. The dealer wanted $345 to diagnose and replace the sensor if it was faulty. I used the guide in the Pit area and replaced the sensor for $150. Then I took the vehicle to a local shop and they erased the codes for free. Everything appears to be working fine now. Thank you for saving me a good deal of money.

 

1660. I have a 2003 GT (HO) with 66k miles. I am having an issue with my front passenger side lock which no longer works with the keyless entry or the buttons to lock/unlock it. All other doors appear to work fine. Could you please help? – Chris, from North Carolina.

If a passenger door fails to lock and unlock possible causes are:

Door Lock Motor - Open
Door Unlock Relay Output Wire Open
Door Lock Relay Output Wire Open
Door Unlock Relay Output Wire Short to Ground Door Unlock Relay Output Short to Door Lock Relay Output
Door Lock Relay Output Wire Short to Ground

Your local dealer will have to troubleshoot and isolate this issue for you.

 

1661. I have a 2002 TE PT with 2.0L engine and 89k miles. Fault P0171 has appeared on my Engine Management System. This appears to be mixture too lean, bank 1. Other than this, my car seems to be running and idling perfectly well. Doing a little research, the lean mixture could be caused by vacuum system leak(s) blocked fuel injectors, dirty MAP sensor, faulty EGR valve? Are these assessments correct and have I overlooked anything? Thank you! - Andrew, from the U.K.

P0171 - 1/1 Fuel System Lean - A lean air/fuel mixture has been indicated by an abnormally rich correction factor.

There are a number of possible causes including:

Restricted Fuel Supply Line
Fuel Pump Inlet Strainer Plugged
Fuel Pump Module
O2 Sensor
O2 Signal Circuit
O2 Return Circuit
O2 Sensor Heater Operation
Throttle Position Sensor Sweep
MAP Sensor Operation
ECT Sensor Operation
Engine Mechanical Problem
Fuel Contamination/Exhaust Leak

The majority of tests performed to rule out each component require the use of a DRB III scan tool and or special equipment which most owners do not have, therefore your ability to DIY will be limited. However the diagnostic that I provided will give you some idea on which areas to focus on.

 

1662. I have a 2001 PT with 35K miles. I live in Costa Rica and there is only one Chrysler dealership and don't know much about the PT, so I have to do a lot of things myself or have them done by my trusted mechanic. The car runs great, but last week the check engine light came on. The self tests gave me the codes P1684 and P0141. After some research I realized that P1684 can be ignored, and after checking the gas cap and disconnecting negative battery cable there is no more check engine light. I read that P0141 indicates 1/2 O2 Sensor Heater Failure, but should I do something about it? Really appreciate any help.  – Forum poster, from Costa Rica.

The battery disconnect will extinguish the MIL light temporarily, however the code is stored in memory and the MIL will reoccur if the issue which originally caused it has not been resolved.  

Fault Code P0141 - 1/2 O2 Sensor Heater Failure. Oxygen sensor heater element malfunction. Possible causes for a P0141 fault code here:

O2 Sensor Heater Operation
O2 Heater Element
O2 Heater Ground Circuit Open
O2 Heater Control Circuit Open
PCM

  I'm afraid that this isn't a DIY repair. It will require the use of a DRB III scan tool, special equipment and a diagnostic manual to diagnose. If the local dealer knows how to use a DRB scan tool they should be able to help you.

 

1663.I have a 2003 GT (HO) PT with 50k miles. Whenever the fuel gets below a quarter of a tank, right after a fill up, the check engine light comes on at start up and stays on. Fault code 0441. I have replaced the purge solenoid, gas cap, and leak detector. When I go to the dealer, they can not find anything wrong, and reset the light. Thank you. – Edward, from Florida.

P0441 Evap Purge Flow Monitor -Insufficient or excessive vapor flow detected during evaporative emission system operation. Possible causes for P0441 include:

Intermittent Condition
Checking Evap Purge Solenoid Functionality
Evap Purge Solenoid Vacuum Supply

It sounds like they may have checked everything except Evap Purge Solenoid Vacuum Supply. If it's ok, it may be an intermittent condition which is more difficult to diagnose. You may have to wait for a complete failure before the can duplicate, diagnose and repair.

 

1664. I have a GT PT 2.0L export PT with 5k miles. The speakers are intermittently cutting out. The radio itself stays fully powered up. Once the sound goes the unit has to be switched off/on before sound is restored. All connections are fine as is the ground to the unit. Any help is greatly appreciated. – Royston, from UK.

Intermittent issues like this are usually related to electrical problems (wiring, loose or corroded connectors, poor grounds, etc). And in the case of audio issues, I would not rule out the radio itself, therefore you may have to work your way through the entire system. Unless you can easily duplicate the issue at will you may have difficulty resolving it.

There have been a few TSB's issued for audio related issues (08-014-04, 08-018-06) which you can review in the Pit area, however none apply to your model year. You'll also find an OE audio diagnostic however it does not address intermittent issues.

If you have already inspected the connections and grounds in the audio system and found nothing suspicious, I would take a close look at the radio given that audio is restored by turning the radio off/on. That said, the service manuals provide no information for radio servicing. In the majority of cases the dealer will simply replace the radio and return yours to the manufacturer. Your vehicle year and mileage suggest that it still covered under the basic 36 month or 36k mile warranty. I would suggest that you have your dealer handle this for

 

1665. We have a pre-owned 2003 GT (HO) with 54k miles. This code keeps reoccurring. We just bought this car and I would like to know what it is and how to fix it. Thanks. – Albert, from Kansas.

P1188 TIP Sensor Performance

Non-boost Mode: PCM detects a significant difference between TIP Sensor signal and BARO Pressure signal.

Boost Mode: The TIP Sensor is unable to read correct boost level.

Possible causes include:

Hoses and Tubing
Vacuum Supply to Surge Solenoid
Solenoid Test #1
Solenoid Test #2
Solenoid Test #3
Solenoid Test #4
Turbocharger
Wastegate Actuator

About the only thing you can check as a DIY'er is the hoses and tubing as indicated below.

Check all of the tubes and hoses between the air cleaner and the intake manifold for loose connection, damage or restriction.

Check all of the tubes connected to the intercooler for loose connection, damage or restriction.

Check all of the tubes and hoses connected to the turbocharger, TIP Solenoid, Surge Solenoid and Wastegate Solenoid for loose connection, damage or restriction.

If the hoses and tubing are ok, your dealer will have to isolate the issue to one of the remaining components. A diagnostic is available through the Pit area, but as I've indicated there's not much you can check on your own.

 

1666. I have a 2002 PT. My overhead (compass/temperature) console recently stopped working. Could there be a short somewhere? – Forum poster, from USA.

Check fuse #14 (20amp) and #13 (10amp) in the interior fuse box. If the fuses are ok, and the overhead console is still inoperative, other possible causes are:    

Fused Ignition Switch Output Circuit Open
CTM Ground Circuit Open
Compass/Temperature Module

 

1667. I have a 2001 LE PT with 90k miles. I tried to replace my front brake pads and rotors this past weekend. When I took the front wheels off, I noticed that there is a black wire running through a grommet from the engine compartment into the wheel well and connected to the front suspension. It looks like a ground wire; on both sides, the wire had broken and was hanging loose. What is the function of this wire, and how important is it? I have not gotten any warning lights on the dash for the ABS, or anything else. Additionally, I was not able to get the old rotors off. Is there a trick to rotor removal in the high-mileage car? Thanks for this great resource and web site! – Albert, from New Jersey.

Black wires are for grounds. I can't tell you specifically what this particular ground is for, but I can assure you that DC would not install anything that is not essential. If you haven't already reattached it please do so.

In some instances the rotors can be stubborn to remove and owners have reported various removal methods. Rust is usually the primary culprit and occurs where the rotor meets the flange and hub surface of the axle. The corrosion in this area can really lock the rotor on. Some of the removal methods are very aggressive. It is assumed that your goal in removing the rotors is to replace, and not reuse them.

1. Try using liquid wrench on stubborn rusty bolts, and allowing them to sit a while before you attempt to remove them.

2. Use a wire brush to remove the corrosion at the hub to rotor surface, than follow up with liquid wrench or penetrating oil and allow to rest. If they're still difficult to remove see suggestion 3-5.

3. Some owners use a hammer or mallet to remove stubborn rotors. You may be able to easily tap them off, or they may require a number of good wallops.

4. Other owners have reported applying heat to the rotor with a propane torch in order to break them free.

5. Some automotive part stores loan or rent pullers which can be utilized to remove rotors.

Think safety when pulling on or walloping the rotor. Make sure no part of your body is under the vehicle. You don't want to pull the vehicle on top of you. Make sure that the vehicle is adequately supported with the appropriate hoisting equipment and jack stands. If you use a hammer, partially thread the lug nuts back onto the mounting studs to avoid hitting and damaging the threads on the studs.

 

1668. We bought a 2002 PT with 102k miles for our daughter about three months ago. It came with two keys, one with a chip and one without. She used the one without the chip in the ignition and later could not get the car to start. We had it repaired and were told not to use the unchipped key in the ignition. Of course with her being 16, she locked her key (the one with the chip in it) in the car. She used the other to open the door and then proceeded to start the car with it. Hence the car will now not start again. Is there something we can do at home, or are we just going to have to tow it and have it repaired. Thanks for your time. – Claire, from Mississippi.

The Sentry Key Immobilizer System (SKIS) is designed to provide passive protection against unauthorized vehicle use by preventing the engine from operating. If you attempt to start the vehicle with an invalid key (the transponder in a valid key is programmed to the SKIS) it will shut down and disable the engine within a few seconds. A trip to the dealer will be necessary to resolve this issue. While you're there have the dealer program you a second transponder key. It will be less expensive than repeated trips to the dealer for servicing.

 

1669. I have a BE PT with 62k miles. The MIL popped on with fault code P0137. – John, from Wisconsin.

P0137 - 1/2 O2 Sensor Shorted To Ground. Oxygen sensor input voltage maintained below normal operating range.

Possible causes are:

O2 Sensor below 2.52 Volts
O2 Sensor
O2 Return Circuit Shorted To Ground
O2 Signal Circuit Shorted To Ground
O2 Signal Circuit Shorted To O2 Return Circuit
O2 Signal Shorted To Heater Ground Circuit
PCM Return Circuit
PCM Signal Circuit

Your dealer will run a diagnostic using there DRB scan tool to pinpoint the issue.

 

1670. I have a 2002 2.0L export PT with 90k miles. All of the interior lights in my PT are permanently on. I have ensured all doors are firmly shut and left the car for at least 15 minutes and the lights are still on. I then went into the car and pushed the upper console push light switches and again left the car for 15 minutes, but the lights were still on. The only way I can get them off is to remove fuse #13. Do you have any experience of this problem? The car had also just completed its annual MOT test. Thanking you for you help. – Andrew, from the UK.

No, we haven't received any reports of this issue. Regrettably, in the US we don't get any exposure to the exports unless an overseas owner brings it to our attention. Possible causes for the courtesy lamps being on at all times include:

Courtesy Lamp Driver Shorted
Drivers Door Ajar Switch
Drivers Door Ajar Switch Sense Wire Short To Ground
Remote Keyless Entry Module - If Equipped
Instrument Cluster
Liftgate Ajar Switch
Remote Keyless Entry Module
Liftgate Ajar Switch Sense Circuit Short To Ground
Instrument Cluster
Instrument Cluster
Panel Lamps Dimmer Signal Circuit Short To Ground
Multifunction Switch

Troubleshooting these components will require a DRB III scan tool. The multifunction switch and Remote Keyless Entry module are components which have failed frequently in domestic PT's however the symptoms that you describe are not similar to other reported failures of these components.

I would suggest that you try resetting the IOD fuse in the PDC. It controls a number of circuits in the vehicle including the cluster. Review all IOD fuse Q&A's in the Tech Library, Wiring subsection before proceeding. If that doesn't resolve the issue your local dealer will have to troubleshoot it for you.

 

1671. I have a 20025 TE PT with 36k miles. The battery recently died and I replaced it. T car runs fine but the A/C doesn't work. The fan blows but the compressor isn't getting any power. I am certain it's a fuse but I can't seem to find where it is. Thanks. – Michael, from Florida.

If the compressor does not engage during A/C or defrost mode recheck fuse #12 (10 amp) in the interior fuse box, and fuse #11 (10amp) in the PDC under the hood. A/C compressor clutch engagement is controlled by the following components:

A/C-heater mode control switch
A/C low pressure switch
A/C high pressure switch
A/C compressor clutch relay
Powertrain Control Module (PCM)

If the fuses are ok, your vehicle still appears to be under warranty, see your local dealer for help in isolating the issue to a specific component in the system.

 

1672. I have a 2001 LE PT with 90k miles. The liftgate does not seem to unlock although you can hear the "click." I'm not sure if there is a problem with the handle or the locks. In any event, I cannot open the rear liftgate. There seems to be an access to enable a "manual release" or "emergency open" but I do not know how to use it. Any suggestions? – John, from Canada.

If the liftgate lock motor fails to lock/unlock possible causes would include:

Liftgate Lock Motor
Door Unlock Relay Output Wire Open
Door Unlock Relay Output Wire Short to Ground
Door Lock Relay Output Wire Open
Door Unlock Relay Output Short to Door Lock Relay Output
Door Lock Relay Output Wire Short to Ground

Your local dealer will have to diagnose and isolate the faulty component. There is no interior latch to unlock the door. You may be access the latching mechanism by removing the liftgate trim panel, however that may or may not be possible if the liftgate is stuck in the closed position.

 

1673. I have a 2002 TE PT with 38k miles. I am having some brake issues. When driving at least 30mph and applying the brakes, I hear and feel a pulsing/grinding sensation in the brake pedal. I took the PT into a brake shop and they told me they could not find anything wrong and there was no metal on metal. Could it be the antilock braking causing this? – Dennis, from Texas.

During normal ABS braking, some brake pedal movement may be felt. In addition, ABS braking will create ticking, popping, or groaning noises heard by the driver. This is normal and is due to pressurized fluid being transferred between the master cylinder and the brakes. If ABS operation occurs during hard braking, some pulsation may be felt in the vehicle body due to fore-and-aft movement of the suspension as brake pressures are modulated.

At the end of an ABS stop, ABS is turned off when the vehicle is slowed to a speed of 3–4mph. There may be a slight brake pedal drop anytime that the ABS is deactivated, such as at the end of the stop when the vehicle speed is less than 3mph or during an ABS stop where ABS is no longer required. These conditions exist when a vehicle is being stopped on a road surface with patches of ice, loose gravel, or sand on it. Also, stopping a vehicle on a bumpy road surface activates ABS because of the wheel hop caused by the bumps.

A pulsating brake pedal can also indicate that the rear brake drum is out of round or a disc brake rotor has excessive thickness variation. I would suggest that you obtain a second opinion to determine the actual cause.

 

1674. I have a 2001 BE PT with 93k miles. A garage disconnected battery, negative first, cleaned the terminals and reinstalled. Every thing works, but the radio. They checked the fuses, which were ok. The lights (bass, treble) blink on the radio. What is proper procedure for disconnecting the battery? Appreciate any help. – William, from New York.

Check the instrument cluster display readout; look for a “no fuse” fault indicator in the display. If you have one try resetting the IOD fuse (PDC #18). Review all IOD fuse info in the Tech Library, Wiring subsection before beginning.

If you didn't experience a “no fuse” fault try disconnecting and reconnecting the battery.

1. Make sure ignition switch is in OFF position and all accessories are OFF.

2. Disconnect and isolate the battery negative cable then the positive cable.

3. When reconnecting, install the positive cable first, then the negative.

If none of the above suggestions resolve the issue review Tech Library, Audio subsection.

 

1675. I have a 2002 PT with 29k miles. If I go for more than 6 days the battery goes dead. The dealer has told me there doesn't seem to be a problem. Everything checks out ok. But something is still going on. The deal suggested that if I'm not going drive the car for 5 or 6 days I could remove the black 20amp fuse located under the hood .Has anyone else had a similar problem? – Forum poster, from USA.

Your dealer is suggesting that you disconnect the IOD fuse (PDC - Fuse #18, 20amp), which controls the majority of circuits in the vehicle. The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery depletion when a vehicle is to be stored for periods not to exceed about thirty days, but it is impractical to do so weekly.  Possible causes for this issue would include excessive ignition off draw, faulty battery or charging issue or system components. I would suggest that you obtain a second opinion. See Tech Library, Engine Systems and Wiring subsections.
