I have a Chevrolet Camaro 2012 and I have three error codes - p0018, p0021, p0346.
It appeared 2 years ago after I swapped engine it appeared immediately and I took 2 years and a lot of money and I still can't fix it.
Recently trying my last- I have changed ECU and programmed it, all 4 camshaft sensors, crankshaft sensor and all 4 oil valve solenoids and the issue was not fixed. It might be wiring issue as my wires look bad. Do you think I need to change engine wiringharness? It's a hard job and I want to know for sure. Thank you
