P0137
If your check engine light is on and you’ve got a P0137 code, that means the oxygen sensor located after the catalytic converter (Bank 1, Sensor 2) is reporting a low voltage reading. This sensor is responsible for monitoring the efficiency of the catalytic converter. OBD2 Scanner: https://amzn.to/42Hw42E
