1995 dodge Dakota code 55? Code 12?


Code 12 means that the battery input to the PCM was disconnected within the last 50 key cycles (this is a normal condition).
Code 55 means that you have reached the end of the codes. This is also normal

So if you have a 12, 55 code readout, you basically have no error codes stored.

Here is a link that lists the code sand what they mean.

Engine codes for a 1998 plymouth voyager


okay, 1998 voyager these are not obd2 codes, these are genric codes, you used ignition to get these .
these codes are for older models that use codes like these 12 35.
the newwer obd 2 use codes like po 013. i will try to see what i can find, also the engine size is important.

okay here we go, the first code is 12, this code means the battery was dead or dissconnected.
the next code 35. this code means loss of prime, code # 11
means internal transmission failure.
the code 55 means gear ratio error.

these codes would tell me that you have transmission problems. this may mean internal trans failure and a rebuild or replacement transmission is needed or shift pack needs replacing. anyhow i would have a shop check this out, these van are known for transmission problems. hope this is helpful good day
