I am receiving the P1039 code on my vehicle listed above. In the last 4 months I’ve had the rear oxygen sensor replaced twice and the from sensor once. I’m thinking it must be electrical?

I clear the codes and the p1039 code eventually comes back although it can be days or weeks when it does.

It seems similar to this issue but I'm not sure how I can message JARADK83 to see how they resolved their issue.

Any advice?

Hello,

The code P0139 can get triggered due to faulty connector to the sensor as well as wiring issue. Sometimes the PCM will need to be reset in order for this code to go away.

I have attached the diagnostic steps for the code P0139 below. Follow those steps as it can help you determine the issue.

Let me know of any questions.

Thank you.
