PCM Replacement


Poobah

Recommended Posts

I'm not sure about this yet, but I might have to replace my PCM. I have absolutely no idea what this might cost, if it becomes necessary. Can someone give me a rough idea?

Thanks in advance.

I've heard anything from $50 for a used one out of the junkyard to just over $100 for a "reconditioned" unit to top dollar at the dealer.

I believe someone else had a link to a place that rebuilt PCM's but I can't think of it. Maybe one of the other board members can recall this.

I doubt it's that cheap. Further, I *think* a dealership would have to be involved in reprogramming the replacement????

IIRC... I think our Guru pointed out that the PCM on ODBII cars are a one shot deal... once they have been flashed with the VIN and other identifying numbers they can not be reused...

But I could be wrong...

Good ones can be obtained for a reasonable price. The PROM chip from your car's PCM is placed into the "new" PCM to maintain the engine parameters that were stored by the "old" PCM.

Have a look at the following thread

The newer versions of the PCM's nail the VIN codes, but I'm not sure when this was implemented.
