So, I get a call from the dealership about my car today and it seems that my PCM is throwing a check engine light. A brand new PCM is an unreasonable amount of money I want to spend. My question is, is there anywhere I can find used parts from a wrecked car? On the internet of course.

My Car:

2000 Honda Civic EX
4 Cylinder - 1.6L
Manual Transmission

Please help!!

 

I think you're talking about the main engine computer, called the "ECU" in Honda circles. Yes you can find used ones easily. It has to exactly match the engine and transmission type you have. Make sure that it is really bad, for example have someone else double check the code it is setting. Usually the CEL comes on for other reasons than the ECU itself.

It's better in my opinion to buy used parts locally because if there's a problem you can take it back in person and demand satisfaction.
