The following is a compilation of Q&A's submitted by enthusiasts and answered by Ask Motor-Mike and Ed.
Part Forty One Q&A 1001 - 1025
1001. I have a 2002 TE PT with 66k miles. Yesterday I noticed that the engine temperature reading was a little erratic on my way to and from work. Normally, it maintains an even temperature reading during my work commute, however today it bounced around on the gauge. When I arrived home I let the PT cool down a bit, then popped open the hood to check the coolant level, which appeared normal, however I noticed that the coolant hoses appeared to be partially closed up. I don't recall seeing anything like that before, what would cause that to occur? -Al, from Rhode Island.
The cooling system is equipped with a pressure cap that releases built up pressure, maintaining a range of 97-124 kPa (14-18 psi). There is also a vent valve in the center of the cap. This valve also opens when the coolant is cooling and contracting, allowing coolant to return to radiator from coolant recovery container by vacuum through connecting hose. If the valve is stuck shut, the radiator hoses will be collapsed on cool down. Clean the vent valve to ensure proper sealing when boiling point is reached, or replace the radiator cap. See the Pit area for additional information.
1002. I have a 2003 LE PT with 13k miles. I can't find any information on the OE ride height (progressive) spring rates. Can you help? - Bruce, from California.
The spring rate of pounds per inch is unavailable to me, nor is it included in the service manuals. I have changed the springs on many PT's and have seen the same spring part number on a base model and limited, even though the parts catalog identifies them as different spring part numbers. I have not found any consistency in spring part numbers for option levels.
1003. I have a 2001 LE PT with 73k miles. Two of the four indicator lights in the power window switch in the center dash console have been out for awhile. I finally took the switch housing out, but can't figure how to get to the bulbs? Thanks. - Robert, from Georgia.
As other PT owners have discovered, the LED bulbs are not serviceable. You must replace the entire switch assembly.
1004. I have a 2002 LE PT with 24k miles. I did not experience any issues with the PT while living in Colorado, however after moving to Delaware the PT has failed to start five times in the past 6 months. The lights come on, there's power to the dash, but the PT will not crank at all. It's been towed five times to dealership and a new starter and battery have been installed. I have an extended warranty, but the dealership has no idea what's wrong. It does not appear to be weather related. I love my Cruiser, any ideas? - Karen, from Delaware.
Intermittent issues are extremely difficult to troubleshoot. My diagnostic would begin with installing 3 test lights. One for the starter relay command signal from the PCM, one from the relay output to the starter solenoid, and one on the starter solenoid terminal. This will tell them where the intermittent open circuit lies. One no-start condition will tell if the power is getting to the relay output, or if the PCM isn't commanding the relay to close. (Mounting the test lights, so they are seen by the driver, can operate for as long as needed. They are only useful for a no-start diagnosis, but will light up every time the PT is started.)
1005. I have a 2001 PT with 65k miles and automatic transmission. The PT is stalling frequently and the self-tests indicate a P1495 fault code. Leak Detection Pump Solenoid Circuit - An open or shorted condition detected in the Leak Detection Pump (LDP) solenoid circuit. Does a part need to be replaced? - Regina, from Pennsylvania.
I'd be surprised to find the Leak Detection Pump causing a frequent stall. A service manual and some EVAP training would be helpful to diagnose the fault. There's no way to know if the LDP is broken, or if the PCM or wiring is at fault.
1006. I have a 2001 LE PT with 58k miles. The instrument light (small lights on window buttons, trac on/off, defogger and speedometer lights) function intermittently. Sometimes they shut down and stay off for weeks, and even months occasionally, then suddenly they start to function normally again. I was told that there might be some wiring that needs to be replaced. Thank you. - Nadeem, from New York.
There are several places to begin diagnosis. There is not a simple answer. The dash and cluster lighting are controlled by the BCM (instrument cluster), via the dimmer and lights section of the multifunction switch. There is an intermittent open circuit somewhere in the lighting circuit. Finding the intermittent fault will take a lot longer than repairing it and is best left to a pro shop that has experience in this area.
1007. I have a 2001 LE PT with 44kmiles, which was previously owned. For the past few months, unless I disconnect the battery and reconnect it, my automatic Key fob does not work properly. It works temporarily, and then only unlocks. It will not lock the doors upon leaving the car parked. I have had to disconnect the battery and then reconnect it to work again. It continues to be a problem. What can I do to fix it? Also, I have never had the fog lights working. Any ideas? - Chantelle, from Puerto Rico.
Every PT is supplied with 2 remote RKE transmitters. Have you determined that the same symptoms occur with both transmitters? If so, then the RKEM is most likely at fault.
The fog light circuit goes from the battery to the fog lamp ground points. There is an open circuit somewhere in between. A wiring diagram, component locator (for splices), and a voltmeter should be all that's needed to find the fault. Visit the Pit area for more information on the RKE Module and wiring schematics.
1008. I have a 2001 LE PT with 47.8k miles. The MIL light popped on about 30 miles into my drive to work on the interstate and has stayed on. I ran the self-tests and received a P 0123 fault code. The dealer can't help with this until they reopen on Monday morning. Thank you. - Bob, from Wisconsin.
The P0123 fault code indicates: Throttle Position Sensor Voltage High - Throttle position sensor input above the maximum acceptable voltage.
1st follow up from owner - Thanks, I fixed the problem by replacing the TSP sensor.
2nd follow up from owner - The problem has returned after about 50 miles. What can I check next? - Bob
The 2001 powertrain diagnostic manual has 11 tests on pages 64-66. They list 10 possible causes. The P0123 code is for the circuit, not the sensor. Voltage and continuity measurements need to be performed. The power and ground circuits need to be verified.
1009. I have a 2004 GT PT with 4.8k miles and automatic transmission. The A/C performance is marginal at best. Using outside (83F) air, the discharge air temperature is cool, not typically cold. In reviewing DC service manual performance charts, it appears the normal temperature drop across the evaporator is approximately 40% less on turbo equipped models...as low as 10 degrees F in some cases. Is this due to added intercooler restriction/heat load in the condenser air path? Have other GT owners reported this issue? - Tom, from Illinois.
We have not received any complaints of this type from other Turbo owners. The turbo creates a lot more heat and the intercooler adds to that effect. My advice would be to test drive another turbo PT to see if the AC is any better. If it is, you may have a faulty HVAC system.
1010. I have a 2001 BE PT with 59.6k miles. Recently, while going to fill up with gas the engine (MIL) light on dash came on. I ran the self-tests and got this DTC - P0551, Power Steering Switch. Is this something I can fix or change out, or is it a dealer repair. I have always worked on my own cars, and rebuilt many engines in the old days. Thanks in advance. - Roger, from South Carolina.
A DIY'er with automotive experience could probably replace the switch, if it were diagnosed as being faulty. However, as you are probably aware, DTC's are the result of a system or circuit failure, but do not always directly identify the failed component or components. Personally, I would have a diagnostic run before replacing the switch.
P0551 (M) - Power Steering Switch Failure: Incorrect input state detected for the power steering switch circuit. PL: High pressure seen at high speed.
Power steering pressure switch - A power steering pressure switch is used to improve the vehicle's idle quality. The pressure switch improves vehicle idle quality by causing a readjustment of the engine idle speed as necessary when increased fluid pressure is sensed in the power steering system.
The pressure switch functions by signaling the powertrain control module that an increase in pressure of the power steering system is putting additional load on the engine. This type of condition exists when the front tires of the vehicle are turned while the vehicle is stationary and the engine is at idle speed. When the powertrain control module receives the signal from the power steering pressure switch, it directs the engine to increase its idle speed.
This increase in engine idle speed compensates for the additional load, thus maintaining the required engine idle speed and idle quality. The power steering pressure switch is mounted directly on the backside of the power steering gear. The replacement procedure is available through the Pit area on the site.
1011. I have a 2001 LE PT with 48k miles. My car was overheating, so I took it to a independent repair shop for servicing. They said there was a leak at the water pump, and needed to replace the pump. With 48k miles on the PT, they recommended replacing the timing belt since it had to be removed in order to access the pump. In doing so, when they put it back together, they heard a lot of noise; they found that there was an update since the 2001 model - the timing belt tensioner, once removed, can't be put reused because it fails to keep the correct tension, which creates a whining, slapping noise. From my understanding, the newer models (after 2001) have an upgraded tensioner that can be put back on repeatedly and still retain the proper tension. Is this true or false? I coughed up $180 for the extra "upgraded" timing belt tensioner and want to make sure I wasn't scammed. - Matt, from Idaho.
There is an updated tensioner. The original tensioner is reusable in most cases. The update does not call for any older year 2.4 engines to have the tensioner changed just for the updated part number. The service manuals make no mention of this concern when removing/installing the tensioner.
1012. I have a 2001 TE PT with 32k miles and automatic transmission. When driving on interstate highways at speeds over 55 mph (I usually set the cruise control at 68 mph in the 65 zones), when on flat terrain the rpm's will suddenly increase from 2800 to 3000, for about 10 to 15 seconds, then drop back down. When going up hills, I understand this is normal. But why am I getting the rpm increase/downshift on completely level surfaces at these speeds? The A/C is not turned on during these occurrences. Thank you. - Peter, from Wisconsin.
It may be your torque converter solenoid unlocking. This would cause an increase in rpm without an actual downshift into a lower gear. Anytime you touch the brake or gas the solenoid will unlock the converter. This may be normal, or there may be something causing the converter to unlock. Only a scanner datastream can record the function of the lockup solenoid.
1013. I have a 2003 LE PT with 500 miles. I've owned several vehicles with 4-speed automatic transmissions, but never one that you cannot downshift to 2nd gear. I miss this feature (I live in a hilly area.) and 2nd gear really saves the brakes. Is it possible to modify the shift mechanism to make 2nd available? - Art, from Canada.
Shifting into low will go into 2nd gear until the speed is low enough to go into 1st gear. 2nd gear is always available.
1014. We have a 2003 BE PT. I swapped the OE radio out with an aftermarket unit about four months ago and have noticed that the battery seems to be weak or discharging. I'd like to check the IOD to make sure the new radio isn't creating any issues, can you provide the IOD specifications? Thank you. - Seth, from Wyoming.
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. A normal vehicle electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control Module (PCM), digital clock, electronically tuned radio, and other modules, which may vary with the vehicle equipment. (Fuse #18, 20amp, in the PDC.)
Excessive IOD can be caused by:
Electrical items left on.
Faulty or improperly adjusted switches.
Faulty or shorted electronic modules and components.
An internally shorted generator.
Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before replacing a battery. In most cases, the battery can be charged and returned to service after the excessive IOD condition has been corrected. See the IOD Draw Test guide in the Pit area for more information.
1015. I have a modified (stockum built motor, Hahn turbo, intercooler, etc.) 2001 LE PT with 36k miles and automatic transmission. The Hahn turbo is only oil cooled when shipped from Hahn - we also water-cooled it. During the installation I think we cracked a heater core inlet or outlet; I have since found out they are plastic. I can smell a small whiff of antifreeze when I initially turn on the heater, which eventually fades away. It looks like a major job to replace the heater core in the shop manual, or my dealer will charge 4.8 hours labor to handle the repair. If I have the temperature control knob to the none-heat position, is the heater core bypassed? I would also assume that the A/C is a separate system, but would like to know if it has to be recharged? Thank you in advance for any input you may have. - Larry, from New York.
The heater core is never bypassed. Engine coolant is circulated through the heater hoses to the heater core at all times. Starting on page 24-28 of the 2002 SM, you will need to recover and recycle the A/C refrigerant prior to removal of the HVAC housing. You may want to leave this one to the pros to handle.
1016. I have a 2002 PT with 48.8km and manual transmission. After only 2 years of regular use, my rear hatch window has developed scratches in the glass, which are impossible to remove. These semi-circular, fine lines are etched into the glass, and oddly, were simply caused by the wiping action of the rear wiper (probably winter grit and sand trapped onto the wiper blade). The wiper blade rubber is as new, and the wiper-blade arm has never been in contact with the glass itself, only the OE rubber blade. I've not yet checked with my local dealer to see if this is a defect covered under the DC warranty. I thought I'd check the matter out with you before heading out to my dealer here in St-Nicolas. Thanks in advance for your advice. - Robert, from Canada.
We have not received other complaints of this type. To our knowledge there are no service bulletins that cover this issue. If you review your warranty coverage, you will notice that the windshield and rear window, are covered for 12 months or for 12,000 miles, whichever occurs first. The warranty states that it does not cover the cost of repairing damage or conditions caused by windshield or rear window damage from external objects. Check with your dealer, but I believe that it's doubtful that they will cover the repair or replace the glass. Another option might be your auto insurance carrier. In the US windshield damage is a standard part of coverage, and in many states, there is no deductible. You may want to review your policy to determine if something like this is covered. If they are unable to help you check with a pro auto glass shop, perhaps they can repair or improve upon the current condition at a reasonable cost.
1017. We have a 2002 LE PT with 88k miles. While parked at the mall recently it appeared that someone might have attempted to break into the vehicle. The alarm system was armed and the system appears to be functioning correctly, however the alarm did not appear to be activated when we arrived back at the car. Thank you. - Sam, from Michigan.
If you suspect that the PT was tampered with you should have heard the Tamper alert feature, which is built into the system, when you arrived back at the car and deactivated the alarm system. This feature is designed to notify the driver that the system had been activated during its armed state. When the vehicle is disarmed, 3 horn pulses will be followed by the initial disarming pulse letting the driver know that the system has been activated.
1018. I have a 2002 BE PT with manual transmission and 50k miles. With no prior issues, suddenly, upon starting, the engine rpm fluctuated up and down. The speedometer showed varying speeds with no speed change and the cruise control light came on and went off - all of this repeatedly. The symptoms continued the next day. On the following day, with the motor idling in neutral, engine rpm dropped whenever the cruise control light came on. Sometimes the drop was enough to kill the engine. When driving at a steady speed, when the cruise control light lit up, the rpm's fell and indicated speed dropped markedly without much real change in speed. The following day the engine would not turn over when the key was moved to the start position. The lights worked normally. I had the PT towed to dealer. - Tom, from Florida.
Follow up from owner - The dealer diagnosed the issue as a faulty drive train control module and replaced it. The PT operates normally now and the repair was covered under the warranty, however I ended up eating the towing and rental car costs.
1019. I have a 2002 2.0L Street Cruiser with 20k miles. I'm having trouble locating the correct VSS signal wire, which my Blaupunkt Satellite Navigation system requires. Could you tell me if this is just available in the engine bay or can it be found behind the instrument cluster as well? If so, what is the color of the wire? Thank you for your assistance. - John, from the United Kingdom.
Page 639 of the 2002 SM shows a white wire with orange stripe as the Vehicle Speed Sensor signal wire from the sensor mounted on the transmission to the TCM and PCM. That circuit is all under the hood.
1020. I have a 2001 LE PT with 80k miles. Approximately 2 weeks ago my PT started to overheat while idling. I took it to a mechanic and he thought it was the thermostat, which he replaced. Three days later were experiencing the same problem. The vehicle was driven about 5 or 6 miles and was running in park, when the needle jumped to red on the temperature gauge. I took it back and they tested the relay, heat pump and fan assembly. The low speed fan was not putting out the speed necessary to cool the fluid so they replaced the fan assembly. That was approximately 1 week ago, and today, on the way to work about two miles from home the engine is once again overheating. My mechanic and his friend at the local DC dealer cannot diagnose the problem. Any help would be greatly appreciated. Thank You. - LeRoy, from Missouri.
The fan control relay is activated by the PCM. The coolant temp sensor tells the PCM when to turn the fans on. The sensor should be tested for accuracy. Also, the coolant should be tested to ensure the temps are above normal. A faulty sending unit can cause the temp gauge to read hot when the engine is fine.
On non-turbo PTs, the low speed fan relay is either on or off. There is no variable speed control. I hope the fan assembly was verified for low air flow prior and after replacement.
You should also verify that the airflow isn't blocked and that the radiator isn't plugged.
1021. We have a 2002 BE PT with 36.5k miles. I am trying to determine the resistance rating for the OE spark plug wires. I have the SM, but can't seem to find the information. - Bo, from Mississippi.
The specs are on page 8I-3 of the 2002 general service manual. Spark plug cable resistance is shown in the index on page 8I-1 of the chapter titled "Ignition control".
Spark Plug Cable Resistance
Cable #1 and 4: 2970 - 8910 ohms
Cable #2 and 3: 2360 - 7070 ohms
1022. We have a 2003 LE PT with the satellite radio option. While washing the PT last weekend I noticed that the sat radio antenna appears to be a little loose. How is it fastened to the roof and can it be easily tightened? Thank you. - Carlos, from Iowa.
According to the 2003 SM the satellite radio antenna is secured by adhesive foam and two retainers, which protrude through a hole in the roof panel. Two wires from the antenna are connected to the body harness above the headliner.
If the adhesive appears to be OK and the retainers are set correctly within the roof, and it still appears to be loose, you may have to replace the antenna. There's nothing more too tighten. I would check with the dealer first, this should be a warranty repair. If you have to repair it, you'll find all the necessary OE guides in the Pit area. To access the area you will have to remove part of the headliner.
1023. I have a 2004 GT Cruiser with about 4k miles. I took the car into the dealer March 11, 2004 because the A/C would stop working after I had driven the car for about an hour. The dealer had the car for a week and replaced the compressor and the A/C low-pressure switch. I drove the car for a few days and it started do the same thing again. I took it back to the dealer, who worked on it for two weeks. They replaced the drier and suction line and the line-A/C suction. I got it back and drove it for a period of time and it gave up on me again. As of today they have had it for two days. They told me last Friday that a tech from Chrysler would be visiting in a day or two to review the issue. I am going to the dealer today and insist on a meeting with the service writer, service manager, technician, and customer service person. If the Chrysler rep arrives in time I would like him to join us. All they seem to be doing is throwing parts at it. The service writer told me when I took it in this last time that it is freezing up. I have noticed an unusual large puddle of water (condensation) under it after I have been driving it. Any suggestions or ideas what is going on? - Charles, from Canada.
It certainly would seem that the evaporator is freezing up. My first tests would be for proper airflow volume. A low speed fan setting or blocked airflow will allow the evaporator to freeze up. There must be enough warm airflow through the coils to transfer the temperature and keep the fins above freezing. Using the lowest blower speed may be the cause.
Follow up from owner - The dealer had the car three different times for a total of eight weeks for the same problem. This last trip they replaced the powertrain control module. The first few replacement modules that they located were faulty. The last one functioned correctly after the technicians at the Chrysler training center (here in Canada) programmed it. (The technician at the dealership did not have the software available on their equipment to program the module.) The A/C appears to be working normally now.
1024. We have a 2002 TE PT with 49k miles. This morning I noticed that the tachometer stopped working. The needle on the gauge just sits there regardless of what mph the PT is traveling at. Is this a repairable item under the warranty? - Arvin, from New Hampshire.
It would be a warranty repair, but it appears that you have exceeded the 36k basic warranty period. The tachometer and two other analog gauges (speedometer and fuel/temp) are integral to the instrument cluster. If any of the individual gauges are diagnosed as inoperable they can not be serviced. The repair will require the complete replacement of the instrument cluster. You might try running vehicle self test A to determine if you're pulling a fault code - it tests the instrument cluster. Additional Diagnosis and Testing for each gauge can be found in the Pit area along with the instrument cluster removal procedure.
1025. I have a 2002 LE PT with 34.7k miles. Last year, at 34k miles, it would not start, the engine would not turn. Chrysler warranty roadside assistance jumped it for me. They checked the battery and said it was low and suggested replacing it. I replaced the battery in November 03, and in March 04, one morning it would not turn over, but just as I was going to call warranty roadside assistance again it started. In July 04, after going to work, and making a brief 10-minute stop to shop, it would not start immediately after I exited the store, but started after I waited about 5 minutes. The following morning, it would not start again, so roadside assistance came again and got it working eventually, but we both noticed that on the odometer it read "no fuse", what does this mean? Since I called Chrysler Roadside assistance could this help me document it for possible a lemon, if this occurs again? Thanks for any help you can provide. - Ubaldo, from Texas.
You seem to have a simple intermittent open circuit. You said, the PT will start after a no start condition. This indicates that the battery is not an issue. No fuse indicates a loss of power to the (BCM) instrument cluster. A good electrical diagnostician should have little trouble locating the bad connection. Lemon laws vary from state to state; you will have to determine the definition of a Lemon in Texas before any judgements can be made. If you need a resource, that information is available in the Pit area on the site. Try to resolve it with the dealer if at all possible, the process to resolve it under the Lemon Law process can often be quite cumbersome. I doubt if a tow truck call will qualify, since they are not certified automotive technicians.
