Any suggestions on what to do?I have the oem dp and catback exhaust and uppipe.Just recently put on a used 02 from a fellow member on here.

 

 

No idea what that code is.

P0134 is the front O2 sensor and P0137 is the rear O2 sensor. No info on P0135 or 136.

 

ok thanks anyone else want to chime in

 

P0136: Rear Oxygen Sensor Circuit Malfunction

 

why would this happen if i put a new 02 sensor?

 

i thought you said you got it used? that might be the problem?

 

yes i did get it used and its a different code from last time so i dont know.Yes th e sensor was used

 

Reset the ECU yet?
Might want to make sure all the connections are clean on the "NEW" used sensor. Might simply be a dirty contact.

I'd check it, then reset the ECU and see if it comes back.

Check engine codes here for future use:

Good luck.
