Hi guys I’m having a code P0140 and p0141. I have a 17 with is38 Apr catted Downpipe. I’m trying to check the wiring harness on the car to see if the oxygen sensor plug is getting a proper reading.
Also if I plug the new oxygen sensor into the cars harness and I cycle the ignition switch to on will the rear oxygen sensor heat up? Or does the car need to be running?
