Electrical P1022 & P1029
I have a 2005 PT Cruiser 2.4 non turbo with approximately 74,000 miles on it.
I hired a mobile mechanic off Craigslist to come and evaluate my car In the end he determined that the P0129 and P0122 error codes were being caused not by faulty wires from the sensors, but the PCM itself giving out errors/failures. He used a multimeter to test the wires and he also tested for a spark.
This all started when about 2 months ago I got a camshaft sensor error and replaced to the camshaft sensor. It was the first major car work I'd ever done, and as a person who fixes computers I thought it was relatively simple. For two days the car did work but shortly after that it began to sputter and stopped running, breaking down in front of a Firestone.
I went back to the O'Reilly auto parts that sold me the camshaft sensor and they mentioned that it may just be a bad connector. I decided to detach the cable and blow compressed air into the connector and suddenly the camshaft sensor seemed to be working.
Weeks later or maybe a month or so (Now) I'm getting these p1022 and p1029 door codes.
I found that the errors can be: No spark, electrical wiring is bad, or the sensor is actually bad, or the PCM is bad.
My question is this mobile repairman off Craigslist is now telling me to purchase a $100 PCM off of eBay and stick it into the car. He wants to charge me $120 to do that.
Will there be any additional steps besides just screwing it into the car and plugging it in? I had a few other auto mechanic places tell me that they would need a specialist to reset or program the PCM?
I appreciate any advice you may have, if this is even the correct course of action I've been told, or not. Thanks in advance!
