Question about 2002 Chrysler PT Cruiser

2 Answers

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

The front oxygen sensor was replaced a couple weeks ago. Checked all fluids and the car is running great. I found a list of the codes but don't understand the code description. Can you tell me what these error codes are, one is to inform that the battery had been disconnected within the last 50 starts but I don't understand the other two. Thank you!

Not all replacement O2 sensors are factory direct plug-in replacements. The rewiring job to fit a universal part to your original harness could be suspect even if the new sensor is fine. I don't see anything to worry about at this point. The codes all seem to be related directly to the repair (inoperable O2 sensor, battery disconnected, bad key). They should go away by themselves over time, but you can hasten the troubleshooting process by erasing the codes from memory. All that takes is a couple of seconds and it can be done with most code scanners. If the codes return afterwards, then you will need to consult with your mechanic.

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.

SOURCE: Engine code P1684

P1684 is not a factory diagnostic code, rather a code to identify last disconnect. Factory computers can identify start counts but OTC scanners cannot. The code prevents someone from disconnecting the battery (which clears many codes) and then reconnecting and having it tested. There is no way I can think of to selectively write more starts than the computer sees into the PCM so as to correct this. I can only think that after about 50 trips, it should be good. BTW, this code would have nothing to do with the emissions on the vehicle. I would suggest driving a few weeks so the computer will (hopefully) recognize the failure again and set more faults. The codes generated by these faults will assist in correcting what is actually wrong with the vehicle.

My 2002 pt cruiser died while I was driving first the oil light came on then it just died! I just had the oil changed 3 days prior to it dying some of the codes I received were 0340 1684 1685...


P0340 is cam position sensor. P1685 is for the key(has a chip in it) P1684 is battery has been disconnected. If the engine will still crank then codes P1684 & P1685 are probably old codes. So if the car will still crank, lets forget about those codes and focus on P0340 A bad cam position sensor will cause the engine to die and not allow it to start back up. Replace the cam position sensor and clear the code and the car should start up.

We change the computer in our 2002 and there are 2 codes showing on the screen. P1684 & P1685


Code 1684 says the computer has lost battery voltage in the last 50 starts, and code 1685 means the security code in the key is not valid.
You may have to have the computer flashed by the dealer to match the original settings in the original computer.

Errors P1684 given, how do I fix


The first code, p1684, just states the battery has been dis-connected in the last 50 start cycles.
Code p0401 is the EGR flow. You may need to replace the EGR valve.
Code p1193 is the intake air temperauture ( IAT) sensor. It may also need to be replaced.
Have your mechanic take a look at those, and please let me know how it goes.
