We have a grand caravan which has given us trouble for awhile now. It has 75,000 miles and the check engine light was staying on. I retrieved the code and it stated PCM was bad, this was the only code it had. The dealership checked it and replaced the PCM free of charge. The light was off for maybe a couple of days and now it's back on with the following codes- P0134, P0135, P0442, P0455. I know what the codes are but why would they just show up after the PCM was replaced? Is it possible this PCM could be bad?
