I had the wiring harness melt together for the rear o2 sensor which i have fixed the harness now. But now i get a code for the wiring harness shorted to ground for bank 1? Before i had both, than i fixed the harness on the back sensor, the front harness seems fine, didnt melt anyplace i can see. I replaced the sensor and im still getting 4.7v at idle, and the r ear is getting about 3.7 at idle. Could a defective computer cause this? Is there anyway that i can check if its a faulty computer? If i buy one and its not it, is there any chance they would take it back if i tell them i didnt use it?
