I got the code 55 when I turned the key 3 times. Can you tell me what that code means?

it will be a special cat code so find a cat dealer and have it deciphered.

Well there are no single digit codes.
Code 12 means the battery power has been lost within the past 50 key starts.
Code 55 means you have reached the end of the code test.

Are you sure is not 5 flashes with a short pause in between and then 5 more flashes? Code 55 indicates the end if the diagnosis.

• Hi, I can help.

• 12 is the actual code.
• 55 Just means there are no more codes stored.

• This code (12) means the ECU has detected low voltage and the

• This can happen if you change the battery or just removed the cables recently to do some car work.

1. First check all the connections to the battery.
2. Check the battery.
3. If both check out and you have recently just unhooked the battery then just let it be. The code is normal in these circumstances.
4. The code will reset itself after you cycle the ignition on and off 15 times. At this point the logic module will use the default values until it relearns the engine attributes again.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Turn key to on ( not start) then off, then on, then off, then on and leave on, and have a pen and paper ready to record flashes of "check engine light". It will flash then pause between second number of 2 digit code. Then a short pause and flash again, pause, then flash. For example: if it flashes 2 times, then pause, then flashes 2 more times, that would be code 22. If it flashes 3 times, pause, then flashes 5 more times, that would be code 35. As I said, there will be a short pause between 2 digits, as well as after number. Write them down as they come up and get back to us with those codes for advice. When you get code 55 ( 5 flashes, pause 5 more ) that means end of message. Those codes should point everyone in right direction of trouble spot.

12-cam shaft position Timing over retarded
31- HO2S heater Control Circuit Low (Needs a new O2 Sensor is what this is telling you)
43- HO2S Heater Control Circuit Low (Bank 1 Sensor 3)
55- HO2S Heater Resistance (Bank 1, Sensor 3)
All of those assume they are supposed to be preceded by a P00

If you are getting ODBI codes these are teh definitions you are looking for:
Code 12 Air flow sensor fault
Code 31 Knock sensor fault
Code 43 EGR fault
Code 55 AV valve position sensor

These may make more sense with that year model.

Not sure what year , make , model, you have but the earlier Chrysler products that would flash codes with key cycled on & off 3 times then left on, code 55 is end of message. In other words, no trouble codes are currently stored.

Turn the key to run then off, back to run, then off, then to run and leave it on. The check engine light will be on and will then go off and then on again according to the codes the engine controler happens to have in it. If the check engine light was on when you stopped the car, then there is at least one code in the controler. The light will blink the codes like this.
Cycle the key three times and leave on on the third time. light on for about 3-4 seconds then goes out for about 2 seconds and then blinks one time and goes out for 3 seconds this is for the no.1. Then the light blinks 3 times and goes out for about 3-4 seconds. You have the code 13. You could have a whole string of codes in the controler memory. It could be something like this. key cycled 3 times, light on for 3-4 seconds, then blinks 1 time, pause, 3 times, longer pause, 2 times ,pause 4 times, longer pause, then 5 times, pause 5 times the goes out.
This is code ; 13,24, 55. code 55 isn't really a code. It just tells you it's the end of any codes the controller has.
If you disconnect the battery and hook it back, you will have code 13 which simply mean 'battery disconnect'. It will errace it's self after several starts if it's not disconnected again. If you cycle the key and you get 55, this means there are no codes recorded at this time.
You will allways get 55 when checking for codes wheather there are fault codes or not. The light on for a few second before the codes start flashing is only a bulb check. Some codes like 13 will not turn the check engine on, but but will leave a code for diagnostic purposes only. If you have the check engine light on and accellerate and the light begains to blink, then the controller is telling you that you have an engine miss and are running the chance of burning out you're catalatic converter if you continue driving. Sometimes its advised to disconnect the battery after you have recorded the codes.
This will erase all codes that are present but were generated by conditions that aren't pertanent to the present condition. and then the codes that come back are the real ones to address.

Contains the entire list of Chrysler Engine Error Codes.

Engine? Those flashes should be 2 digit numbers . Cycle key, on, off, on, off, on & leave on & recount those flashes. Example: 3 flashes, pause, then 3 more is code 33. Or 2 flashes, pause, 4 flashes, is code 24. 5 flashes, pause 5 more, is code 55 which means end of message. Then get back.

The codes can be pulled from this car by turning the key to off on off on off on then on the forth time leave the key in the on position and observe the check engine light it will blink in two number codes for example 3 blinks then a pause and 2 more blinks would mean code #32. Here is a link to the codes table:

These codes for a 95 2.5 should be the same for your 88.
