Part Forty Q&A 976 - 1000
976. We have a 2002 TE PT with 27.5k miles and manual transmission. The other day, during a long run at a steady 60-65mph, my wife, who was in the car behind me, reported that my backup lights lit up on a couple of occasions, staying on for a few minutes at a time. I had no lights on, was not using the wipers, was steady in 5th gear, rarely used the turn signals or brakes, and I don't drive with my hand on the shifter. She could deduce no observable correlation (lane changes, braking, etc) with these occurrences. No codes were detected with either self-test (except the FL005, EE05, BL01 which you, rightly I think, correlate with internal software data). No new wiring or tampering on my part to account for it. Any ideas would be appreciated? - David, from Delaware.
The 2.4L with manual transmission goes through a back-up lamp switch that ties 12V power to the lamps. There is no other way for the lamps to get power. It must be a defective switch, or defective switch activation lever inside the transmission. Reference pages 8W-51-2 & 3 of the 2002 SM.
Follow up from owner - Yes, it was the switch. Good call. You are a lot better than I am at making sense out of those wiring diagrams.
977. I have a 2002 LE PT with 65k miles. I need to know how to program a keyless lock control if I don't have one already. The instruction say to use the RKE transmitter programmed to the RKE module. However, I don't have one. I picked up a transmitter at the Chrysler parts department and they said to read the owners manual. Unfortunately those pages were missing from the worn out book. I reviewed your instructional guide and couldn't do it since I didn't have an already programmed transmitter. Can I do it or is this an impossible thing? Thanks. - Linda, from Arkansas.
As you stated, in order for the owner to program a new RKE transmitter FOB they must have a functional previously programmed FOB. Without one, the dealer will have to handle the programming using their DRB III scan tool.
978. We have a new 2004 GT PT with 8 miles. Is it common practice by dealers to mount the front license plate bracket without customer consent? Our brand new PT now has 4 holes drilled into the beautifully painted bumper and I can not use a relocation bracket without revealing the holes. - Dave, from California.
There is no standard. Some dealers install them without asking; others ask the customer first. The best approach is to ask the dealer not to install the tag when they are prepping the vehicle for delivery, however it's not something most buyers think about during the transaction unless they have previously experienced or read about the unsightly holes, once the tag is removed. They are especially distracting on a painted bumper.
You can read about a few repair techniques here, however these techniques are more practical with the earlier unpainted bumpers. You may be able to utilize these methods and some Mopar touch up paint to come up with a workable solution.
Other GT owners may want to reconsider locating the tag underneath the bumper given the possibility of blocking necessary airflow to the intercooler.
979. I have a 2001 LE PT with 40k miles and would like to add an automatic transaxle gear indicator to the dash. I was thinking four blue LEDS, one for each four speed of the transaxle. I was wondering if there were some wires that could be tapped to do that? Thank you. - Mario, from Italy.
The solenoids that control shifting are inside the transmission solenoid pack, which are inside the transmission. There is no simple group of wires that will light up a lamp for each gear.
980. We have a PT Cruiser and would like to know the location of the airbag sensors on the front? Could they deploy from a sliding impact into a side of a mountain? Thank you. - Edward, from the USA.
The front airbag system electrical circuits are continuously monitored by a microprocessor and software contained within the Occupant Restraint Controller (ORC). The ORC also contains impact sensing elements, which are monitored by the ORC to determine when an impact occurs that is severe enough to require front airbag system protection. The Occupant Restraint Controller (ORC) is mounted on the tunnel floor pan, between the transmission shifter and parking brake, under the floor console. The impact sensing device is an accelerometer that senses deceleration, which provides verification of the severity of an impact.
If equipped with side air bags, the Side Impact Airbag Control Modules (SIACM) control the seat back mounted airbags (one left and one right). If a SIACM determines the impact is severe enough, the appropriate airbag will inflate, tearing open the front seat back trim cover protecting the occupants. One SIACM is located on each side of the vehicle within the body B-pillar. Each SIACM contains two accelerometers, both accelerometers must agree in order to deploy the seat airbag.
No data is provided, which would indicate the severity of the impact necessary to deploy the air bag. To learn more about the restraint systems please review the system guide in the Pit area on the site.
981. I have a 2001 2.4L BE PT with 34k miles and automatic transmission. The engine light came on and the transmission changes gears from 1 to 2 very sharply, but other gears shift normally. The vehicle self-diagnostic provided fault code P0700. I took the car to dealership and they read TCM fault codes and did some kind of a CVI test. They say that second clutch is faulty and transmission needs to be changed. Here are fault codes: P0733, P1790, P0720 and P0715. What is your opinion? - Janne, from Finland.
The P0700 fault code only directs the technician to look in the transmission section for fault codes.
The transmission codes are all related to measured errors in engine rpm. They all request the technician to record the CVI clutch volume index for possible faults in the clutch packs. I would not allow the dealer to repair only one clutch pack. If one is bad, the others may be right behind it, waiting to fail. I would only accept a new 'crate' transmission, not a rebuild of the old one. To change a clutch pack, the entire transmission must be disassembled into hundreds of parts. The labor time to rebuild it may be more than the cost of simply installing a new transmission.
982. I have a 2002 BE PT with 32k miles. Thanks to the site, I was able to remove and replace the spark plugs. When I removed the intake plenum, I noticed an odor of oil. I realize the PCV vents via the intake and I was wondering if this was normal? Coincidentally, the car has started to use about 1/2 quart of oil every 2200 miles. I've been changing it every 3,000 to 3500 miles and use Mobil 1. Other than that, the car is running well and getting 23 to 28mpg. Thanks. - Mark, from Minnesota.
Yes, that is normal. For the most part, there have only been a few reports of unusual oil consumption beyond the 2001 models (with the defective oil baffle in the valve cover). They used oil from the day they were built. There is a valve cover mod to cure the 2001 models that were affected by this issue, however this has not been an issue with later model years. As is noted in the Top 10 List, some owners have reported what they feel is excessive oil consumption to their dealers, who have, in most instances indicated that this is normal for Chrysler products. That said, as a precaution, you might want to document the finding with your dealer in case it becomes more severe. You can read more about this issue in the Top Ten Issues List.
983. We have a 2001 LE PT with 39k miles. Recently the motor (that controls the mirror) inside the driver side power mirror stopped working. Can the motor be repaired or replaced? Thank you. - Chad, from Oregon.
The service manual states that the foldaway mirror motor is not serviceable separately and if a motor is found to be faulty, the entire side view mirror must be replaced. If you need one, you'll find a replacement guide in the Pit area.
984. I have a 2001 2.0L LE PT with 40k miles. I haven't had any problems with the PT, but yesterday, I noticed that maximum speed is 160 km/h! Chrysler says minimum is 190km/h. What is your opinion? Thank you. - Mario, from Italy.
It should run around 190kph, or 113mph, but I would not expect safe handling or braking at those speeds.
985. I have a 2002 TE PT and would like to know how the PT's engine electronics maintain an optimal air/fuel ratio? - Alan, from Wisconsin.
The PCM can adapt its programming to meet changing operating conditions. Fuel is injected into the intake port above the intake valve in precise metered amounts through electrically operated injectors. The PCM fires the injectors in a specific sequence. Under most operating conditions, the PCM maintains an air fuel ratio of 14.7 parts air to 1 part fuel by constantly adjusting injector pulse width. Injector pulse width is the length of time the injector is open. The PCM adjusts injector pulse width by opening and closing the ground path to the injector. Engine RPM (speed) and manifold absolute pressure (air density) are the primary inputs that determine injector pulse width.
986. We have a 2002 LE PT with 41k miles and noticed that the power doors will not lock when the door is ajar. Is this normal for the PT, or is there a problem? Thanks. - Alice, from New Hampshire.
The PT utilizes a Door Lock Inhibit feature. With the key in the ignition switch and the driver door open, the Remote Keyless Entry (RKE) module will ignore the command to lock the power door locks using the interior door lock switches. Once the key is removed, or the drivers' door is closed, the RKE module will allow the power locks to lock using the door lock switch.
987. I have a 2001 LE PT with 61.5k miles and automatic transmission. What kind of horsepower increase can I expect from a set of performance headers coupled with a high flow exhaust? Also what is the difference between 4-2-1 style headers compared to 4-1 style headers? Thank you. - Elliott, from California.
Although I have installed several headers from different manufacturers, I would not put another one on my own PT. The cost per horsepower is too high. The gains are minimal. The OEM exhaust manifold is fairly well designed. You'll find more on the exhaust system in the Tech Lib under Performance Mod's, and two JBA header installation guides in the Pit area on the site.
In addition to the OEM manifold, Borla, JBA, APC, and even the entry level Headman are all 4:1 header designs. It's Headman's marketing scheme that created the 4-2-1 header. No one has posted independent dyno tests of each design, so it is difficult to suggest a specific style.
Generally a 4:2:1 header design (4 primary pipes come off the head. Cylinder 1 and 4 come together, and cylinder 2 and 3 come together; then those two pipes merge further down into one outlet.) is used on street driven cars. It helps to conserve and sometimes improve the midrange torque.
A 4:1 header design is generally used on vehicles that see all upper end rpm usage, which typically show loses in midrange torque, but a very peaky upper end hp increase.
988. I have a 2002 BE PT with 17.5k miles. The rear hatch ajar indicator and alarm come on, even if the door is completely closed. It occurs more frequently after the vehicle has been washed. - Martin, from New Jersey.
There are 3 possibilities:
1.The door switch is faulty or misaligned.
2.The wiring is shorted to ground between the switch and the module.
3.The module is faulty
The switch is the most likely the problem. Either way, it's under warranty and your dealer will repair it.
989. We have a 2003 TE PT with 17k highway miles. The engine is running rough and pulsing, and lurching forward while stopped. The dealership said it had a bad spark plug and warped rotors. The service department said warped rotors are rare, but won't replace them under the warranty. My wife works with three individuals who own PT's and all of them have replaced the rotors at or before 20k miles. I think the service manager is full of crap and this is a common problem! - Bill, from Oregon.
A number of owners have reported brake issues related to early brake pad replacement, and we have received some reports, which suggest that owners are replacing their rotors, due to wear, during the pad replacement. Replacing the rotors along with pads is very common on newer cars. The new rotors are thin and lightweight to cut costs, and very soft to reduce noise. On the plus side, new rotors cost much less than they used to.
From time to time warped rotors have been reported, however this has not been a common occurrence. The fact that your brake pads are OK, doesn't necessarily confirm a deficient rotor. Warped rotors can be caused by a variety of factors. For example, a common cause of warping is over-torquing or unevenly torquing the lug nuts. Overheating the brakes can also cause rotors to warp. The rotor can also become warped or have an uneven or high spot on the surface due to normal wear and tear. Hard spots in the metal due to casting impurities can also be a factor. Defects in the rotor casting, such as thick and thin areas can also cause uneven cooling that leads to warped rotors. If you know of other owners with rotor related problems, I suspect that their issues are more related to wear then warping.
The warranty on the pads, rotors, lining and drums is 12k miles or 12 months, whichever occurs first. Technically, you are just out of warranty. In a gray area like this you will find some dealers who will honor the warranty, even if it's out-of-pocket for them, in order to keep their customers happy, and some dealers who will not. If you do not agree with the dealers' diagnosis the next step would be to get a second opinion and or contact DC directly and appeal to them for help. You'll find a complete section on brake and rotor related issues in the Top Ten Issues Report, located in the Pit area, along with suggested aftermarket replacement parts, which will outlast and outperform the OE components.
990. I have a 2001 BE PT with 27.5k miles. When the moon roof is open in the vent position, the "close button" has to be pressed numerous (9 or 10) times to get it to fully close. When in the vent position, if you press the "open button" the roof closes and retracts ok and can then be closed without a problem. The dealer has been unable to fix it because the problem is intermittent. The warranty expires in July; can you help? - Robert, from Ohio.
Given your complete description and the wiring on page 8W-64-2 of the 2002 service manual, I would strongly suspect the Power Sunroof Module as being intermittently faulty. The switch is part of the overhead console module, and seems to be working correctly. The motor functions correctly, if it's given the correct command from the module.
991. I have a 2001 TE PT with 62k miles. I wondered if you knew what the warranty on the PCM is? I understand that emission control items have a longer warranty than the standard 3/36,000. I can only hope because mine has gone bad and the dealer wants $480 to replace it. Thanks for your help. - Michael, from Delaware.
Unfortunately the PCM is covered under the basic limited warranty coverage of 3 years/36,000 miles. You can verify this in the warranty coverage booklet, which was provided by the dealer when you purchased your PT.
992. I have a 2001 LE PT with 45.5k miles and automatic transmission. I started the car and the instrument lights came on and off like normal during start-up, except that the airbag light came on and never went off. The light stays lit after starting and only goes off when the ignition is turned off. Is there a simple fix? - Bill, from Texas.
The airbag indicator lamp in the instrument cluster lights for six to eight seconds as a bulb test each time the ignition switch is turned to the ON position. Following the bulb test, the airbag indicator lamp is turned ON or OFF by the Occupant Restraint Controller to indicate the status of the airbag system. If the airbag indicator lamp comes ON at any time other than during the bulb test, it indicates that there is a problem in the airbag system. Such a problem may cause the airbags not to deploy when required, or to deploy when not required. The dealer must diagnose the system using their DRB scan tool to determine the exact nature of the problem. (It can be helpful to conduct and provide us with the results of the two vehicle self-tests when you experience a MIL related issue like this.)
993. I have a 2001 LE PT with 77k miles and manual transmission. Recently while taking off from a standstill, in 1st and 2nd gear it felt like the clutch was slipping. Then later that week, the MIL popped on. The DTC was P0302 - Misfire in cylinder 2. So I went about replacing the wires and plugs. (This is my second tune up.) It resolved all of the issues I was experiencing, but I am not sure how to reset the check engine light and clear the code. Thank you. - Francis, from New Jersey.
The code will clear the light after a pre-set number of drive cycles. It can also be cleared with a DRB scan tool by you or the dealer.
994. We have a 2003 LE PT and recently went on vacation out of state. The PT ran well and we didn't experience any issues while vacationing. On the way back there was a serious accident on the interstate, which backed up traffic for many miles. During this very lengthily (about two hours) stop and go process the engine temperature began to rise and eventually started to overheat. At one point we heard several chimes, but couldn't determine the cause. Once we were clear of the accident the engine temperature started to drop and the PT ran fine again, but what was that chime about? Thank you for any help you can provide. - Barbara, from Georgia.
When the PT overheated, the engine temperature warning light was probably activated. During this process, if the engine becomes critically hot, a warning chime will sound 10 times. After the chime turns off the engine will still be critically hot until the temperature warning light goes out.
995. I have a 2005 GT Convertible with 200 miles. I guess as a cost cutting measure, DC eliminated the foldaway heated power outside mirrors on my new 2005 convertible that I have on my 2001 PT sedan. Is there any way to retrofit 2001-2002 foldaway heated power outside mirrors to my convertible? I'm not so concerned about the heated feature (that would be nice, but not absolutely necessary, as this car will never see any snow or ice), but would the older unit possibly bolt on and use the same power connectors? - Clyde, from Connecticut.
We haven't had an opportunity to work on the convertible, nor are the 05 service manuals available at this time. The older service manuals indicate that the foldaway side view mirror is attached to the vehicle's door in the same manner as mirrors without the foldaway option. I would venture to guess that the mirrors remained the same, and the older folding units will fit, but I doubt if the wiring is there for the heaters.
The optional heated mirror system only operates in concert with the rear window defogger system. When the rear window defogger switch is in the On position, an electric heater grid located behind the glass of each of the outside rear view mirrors is energized. When energized, each heater grid produces heat to help clear the outside rear view mirrors of ice, snow, or fog. A momentary rear window defogger switch in the accessory switch bezel controls the heated mirror system. An amber indicator lamp in the switch will illuminate to indicate when the defogger system is turned on. The rear window defogger switch also contains the defogger system control circuitry including the timer logic and the defogger relay.
The OE wires for the power mirrors on the 2004 model were:
Left Mirror - Connector 204
Dark blue/white - left/right function
Yellow/brown - up/down function
Yellow/pink - power
Light blue/yellow - heater
Right Mirror - Connector 205
Dark blue/white - left/right function
Yellow - up/down function
Pink - power
Light blue/yellow - heater
Follow up from owner - Now that I have looked closer, the mirror plate that bolts onto the door is a totally different size on the convertible (its bigger) than on the sedan. So I guess that ends that (unless I can come up with an adapter plate that would bolt onto the car and then the mirror would bolt onto it). I'll let you know. In the connectors that the mirror wiring plugs into (that come up out of the door) there are 2 extra wires. Perhaps they're for the heated part of the mirror. I haven't checked with a voltmeter yet to see if any voltage is present when the rear window defogger switch is turned on.
996. I have a 2003 DC (Turbo) PT with 16k miles and automatic transmission, What is the off set of a 17" turbo rim? - Don, from Florida.
17" Cast Aluminum, Chrome Plated Wheel
Diameter 17.0 inches
Width 6.0 inches
Bolt Pattern 5 x100mm
Wheel Offset 39mm
Tire 205/50R17 93H Goodyear Eagle RS-A Radial
Revolutions per Mile 832
997. We have a 2002 BE PT with 41k miles. We park the PT in the garage, but occasionally our two young sons forget to shut the door completely. Fortunately, up until now I have noticed the interior lights and open door and it hasn't created any problems, but I'm afraid that I'll miss it one day and we will wake up to a dead battery. Any suggestions would be appreciated? - Lawrence, from Oregon.
The interior lights will automatically turn off in about 8 minutes if a door is left open or the dimmer control is left in the dome light position. To restore the interior light operation, turn the ignition switch On.
998. I have a 2003 TE PT with 14k miles. My MIL light is flashing when I drive. The car shakes very badly when in idle, and when I drive it loses its acceleration and jerks very badly at 45 to 50mph. I tried running the two self-tests, but they read F005 and E11, never got a "p" code. - Cindi, from North Carolina.
We believe that the readout you mentioned represents the software revision level of the cluster, not MIL codes. The two self-tests have limitations on the vehicle systems they check. In many cases a DRB Scan tool must be utilized to identify all of the fault codes. A flashing MIL implies that a serious condition may exist that could lead to some of the symptoms that you are currently (loss of power, etc.) experiencing, and or severe catalytic converter damage. I would suggest that you have the vehicle checked by your dealer ASAP. They will utilize a DRB scan tool to diagnose the concern. I would not attempt to drive the vehicle for any other reason. If you don't have a dealer fairly close by call them first to determine if the PT should be towed or driven in. (If the behavior began immediately after the oil change, check the 4 ignition coil wires and make sure they are all firmly connected to the spark plugs. Perhaps they inadvertently dislodged one while under the hood. Normally you would see a fault code for a misfire.)
Follow up from owner - I ran the self-tests again and got the code (must of been doing something wrong) P0303 (M).
PT DIY Follow up - The P0303 (M) code indicates: CYLINDER #3 MISFIRE. Misfire detected in cylinder #3.
Check the ignition wire connection to the plug. If the connection is OK, it's probably a faulty ignition wire or plug. It's not likely to be the ignition coil, they're pretty reliable and don't fail often. There is a way to diagnose the wire and plug, but unlike with plug #1 and 4, which you can access easily, plug #3 and 4 can not be accessed unless you lift the upper intake manifold cover. Review the Spark Plug replacement guide in the Pit area for insrtuctions on removing/lifting the upper intake manifold.
Once the manifold is lifted you can test the wire and plug using the method outlined here, except of course, you'll be working with different cylinders. Incidentally, do not mess with the ignition wires with the car running or with the ignition turned on. The coil puts out HIGH voltage, which could potentially zap you badly.
If it is the plug, you may want to give some thought to changing them all out at the same time. See the Spark Plug Specifications chart and important TSB related to the OE plugs for the 2003-2004 model year here.
Follow up from owner - We changed all of the spark plugs and it runs like a champ! The information on the site was very helpful (more so than the dealership). Thanks.
999. I own a 2001 LE PT with 13k miles. I am trying to access the battery so that I may charge it. I tried charging it through the remote jump start terminal and grounded the negative clamp of the charger to what I thought was a good grounding spot inside the engine compartment. Unfortunately I fried the battery charger. Thank you for your help. -Richard, from California.
The service manual indicates that the battery should be charged at its terminal post, not the remote jump start terminals. (The negative remote jump start terminal is located above the radiator latch.) Always disconnect and isolate the battery negative cable before charging a battery. Do not exceed sixteen volts while charging a (2.4L engine) battery. Damage to the vehicle electrical system components may result. To access the battery, remove the air cleaner assembly lid by loosening the hose clamp, which holds the flexible air intake hose to the air cleaner assembly lid. Once the hose is loose, pop open the two spring-loaded clips - one on each side of the air cleaner lid, then remove the lid to access the battery. Additional information on these procedures is available through the Pit area on the site.
1000. I have a 2001 LE PT with 71k miles. What is the best way to get wires from the engine bay into the interior? I need to get wires from a P.A. speaker in the engine bay into the car. Thank you. - Bobby, from Georgia.
Attach the wires to a straightened metal coat hangar and thread the coat hanger through the hood release cable plug in the firewall from inside the engine bay. The plug is located on the lower right quarter portion of the firewall, below the hood alarm switch. Look for a small hole with a grommet and rubber coated hood release (stiff) cable passing through it, with a larger hole with many wires beside it. From the interior of the vehicle, pull down on the hinged panel under the steering wheel to drop the panel and access the hangar and attached wires under the dash. You'll find more information and photos on the procedure in the Pit area.
