Title: P0136 O2 SENSOR FAULT
Post by: Lou1 on 03 February 2025, 11:58:50

HI all hope your well, can anyone explain why I would still have a P0136 code after changing the O2 sensor on bank 1 sensor 2 ?

Might be a faulty connector or something in wiring loom of that particular sensor. If the error code is absolutely correct.

You need to read live data from the sensor to determine why the code was logged. It doesn't necessarily mean the sensor is faulty; values outside the expected range will do it too.


As mentioned above, some possible causes could be damaged sensor wiring, faulty exhaust, injector or ignition problems or even an air leak into the engine.


Fault codes aren't definitive 'replace this part' messages without proper further diagnosis.

Or the sensor is working fine and you've totally failed to fix the cause.
