2002 Chrysler PT cruiser has only 28,000 miles the engine light came on. I retrieved error codes p0134, p1684 and P1685. I found a list of the codes but no description. Can you tell me what these mean


I found the codes & basic (VERY basic) descriptions from these sources:
http://www.ptcruiserclub.ru/ptobderr.htm

http://kentuckyptcruisers.weebly.com/obdii-codes.html

Code P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1) - something to do with the O2 sensor circuit, but beyond that I'm not sure.

Code P1685 Skim Invalid Key - Security system issue. I got this answer from the Dodge Forum:

"The Sentry Key Immobilizer Module (SKIM) is part of the security system and kills the vehicle when a wrong key is used. There may be a problem with your key or the chip reader in the ignition switch. This is something the dealer will need to determine for sure. This code will also be set if someone actually tried to steal the vehicle."

Hope this helps.

You probably need to replace the temperature sensor. It is located on the intake manifold, below the thermostat housing.

P0702 p1685 fault code on 2.7crd merc transmission


DTC P0702 - Transmission Control System Electrical
There is a code in the ****** control module and need to check harnesses and wiring, as first step.

DTC P1685 - Skim Invalid Key
Transponder ID (in ignition key) is monitored with ignition on. DTC will set if transponder ID read by Smart Key Immobilizer Module (SKIM) does not match any transponder ID's stored in SKIM memory. Possible Causes:
- Incorrect VIN In PCM
- Invalid SKIM Key Present
- No Communication With SKIM
- No VIN Programmed In The PCM
- PCM SKIM Trouble Codes Set

I would suggest clearing all these codes, and drive it until the problem arises again, or the check engine light comes on, and then check for codes again. To clear the codes you will need to remove the negative battery cable, and touch it to the positive cable, for about 15 seconds. Then re hook and all the modules will be reset. If this isnt work, visit your Trans Service.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.
