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."

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.

Problem code P0700 y P1685


P0700 - Transmission Control System Malfunction
Basically what that means is that a malfunction has been detected in the transmission and associated components. There is good news and bad news. The good news is it might be covered under warranty. You didn't say if your vehicle is still under warranty, be aware that you may still have warranty coverage on this since your car is just 3 years old. The bad news is that the P0700 code really means that there are transmission-specific codes that you can't access with a regular code reader. There is a part called a TCM - transmission control module that works in a similar way to your PCM. The TCM handles the transmission electrical "stuff" and it stores further transmission codes.

If you want to pursue the issue yourself, you'll need to get your hands on a higher end code reader, or take it to the dealer or a transmission shop to get the actual transmission trouble codes read. Personally we recommend you get a shop to read those codes for you. The other codes are communication codes, we recommend you clear those codes after you fix the P0700 code and see if they come back, they could be related to the "main" transmission issue. The other good news is the fix for this may just be a software update that the dealer can do.

P1685 - SKIM Invalid Key.
The engine controller has received an invalid key from the SKIM.You need to take it to the dealership so they can reprogram the key, Sentry key system.

Good luck.

I have a 04 pt cruiser with airbag light and chime intermittent fault code p1685


p1685,,"skim invalid key"
I have no idea what they are talking about, but that is the code.

DTC P1685 is Invalid SKIM Key. 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.


My guesswould beto reset your PCM (unhook bat. and depress brake for 1 min), then try to start the car. If that doesn't work, I guess haul it into a dealership so they can run a diagnostic quote.gif

I got this from another site, check it out.

2000 neon check engine light is on


P1685 Skim Invalid Key.

The Sentry Key Immobilizer Module contains a Radio Frequency (RF) transceiver and a microprocessor. The SKIM transmits RF signals to, and receives RF signals from the Sentry Key transponder through a tuned antenna ring integral to the SKIM housing. When the ignition switch is turned to the On position, the SKIM transmits an RF signal to the transponder in the ignition key. The SKIM then waits for an RF signal response from the transponder. If the response received identifies the key as valid, the SKIM sends a valid key message to the PCM over the PCI data bus. If the response received identifies the key as invalid, or if no response is received from the key transponder, the SKIM sends an invalid key message to the PCM. The PCM will enable or disable engine operation based upon the status of the SKIM messages.
