I was told Bank 1 sensor 2 O2 sensor has heating circuit defective. Error code P0037 and P0136 I replaced the sensor, I disconnected the battery for about two minutes, but the error code and engine light did come back. What can be wrong? I know that the sensor I used was working sensor. The sensor I used was a NTK make.
