I just had a check engine light come on it was a tps sensor and oxygen sensor the rear heated one. I erased the codes and they both pop up again and I changed the sensors again thinking it might be faulty sensors and put new ones again and erased the codes on the odb meter from auto zone and they pop up again. What is wrong or am I doing something wrong

Hi allanader,

Thank you for the donation.

What were the exact trouble codes?

If replacement of the parts did not help, you would need to test the wiring and the PCM.

Those should have been done before the parts replacement.

No I have not heard of this. When the ECM cannot communicate with the scanner, there could be some problem with the wiring, fuses or the scanner used is not compatible. Get a second opinion.
