Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I've seen this once before. The car needed a PCM/ECM reprogram after the body work was done. I'm not sure why. I really never understood what happened; this car was in a front end collision and after the body work we kept getting p0236 and p2227. We checked and replaced the boost pressure sensor and then checked grounds and the connector at the PCM/ECM. After wiggling the connectors and making sure they were seated we performed a reflash on the PCM/ECM and the codes didn't return.
It's possible that the ECM connector was just knocked loose in the accident, but it still wouldn't keep the codes off until after the re-flash.
Did you need any additional help with this?
