My 98 XJ had the downstream 02 sensor wire and harness damaged from contact with the driveshaft so I had to cut the wire harness off and splice it directly to the wires of my new 02 sensor. Since then I have code P0138 for incorrect voltage or faulty ground coming from those wires. I have rewired the connection twice now with no difference.
I found a downstream 02 sensor wire harness from a 2001 TJ with a 4.0. It looks identical to the one from my XJ. Sorry if this is a stupid question but couldn't I just use that harness from the TJ? I am having trouble finding one for my XJ new or used and I really want to solve this check engine code. Thanks!
