Hello all, I just bought a one owner 05 TJ with 90k on it. I have a check engine light on for all 4 sensors. I found the positive signal wire for the starter melted against the block I'm not sure if that has maybe shorted out the PCM I'm hoping you all can help me.
O2 sensor circuit codes
- Thread starter Brokenbenz717
- Start date
Send your PCM to @Wranglerfix (https://wranglerfix.com) and Mark will diagnose it for you to make sure it isn't the PCM. There's a good chance that it is, especially since it's a 2005.
The starter wire shouldn't have anything to do with these O2 sensor codes, but I would fix it first just to be sure.

@Wranglerfix No it has ran fine so far however I do not have power to my fog lights unsure if it’s related. Power at fog fuse no power at relay
@Wranglerfix The customer I got it from said the light would go on and come off and the dealer diag said it was a ecu sensor
Faulty O2 sensor readings is the pcm failing on an 05-06 TJ. You can call me to discuss in further detail if you would like.
