Order of inspection
P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2) Low
The P0136 code means the oxygen sensor located after the catalytic converter is not sending a sensible signal. Its job is not to correct the mixture but to watch converter efficiency, so the engine keeps running normally while the system loses the ability to judge emissions.
