Hey guys, this is a repost from the Australia forum, just though you guys over here at techs might have some knowledge on the issue..

The other day i noticed a CEL light which had come on but switched off but come on again. Took her into Mazda and they told me it was throwing a P0610 code but told me there was a loose connector and hopefully that solved the problem, and if the light came on again, i probabaly had a faulty PCM.

Lo and behold the light came back and they said they rang Mazda Technical and concluded i have a faulty PCM. They have been quite helpful in helping me out and suggested they could have the PCM repaired instead of replaced at a cheaper cost.

My question is though, my car is driving fine, bar the light she is better than ever, and I am reluctant to spend more money to fix something that may not ever become an issue? Or at least hold out for a while until I have more money to fix it.

What risks am i taking if i continue to drive? And why isn't the car showing any signs of fault if the PCM which controls the engine etc is faulty?

If your car drives fine then its probably bad harness.

The Mazda tech told me a few diodes were blown and that it would need replacing. I doubt they would have missed a bad harness when they were diagnosing it.

But the car still drives fine and until I can figure out what caused the problem putting a new PCM in will just blow it again i think.

Computer parts generally don't wear and tear so i think i should be fine driving until i find the cause of the PCM failure? Or maybe, if the car drives well i may not even need to replace it at all?

Any thoughts?
