P0165

02 Sensor Circuit Slow Response (Bank 2 Sensor 3)

DTC P0165, sometimes indicated as P016500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing 02 sensor circuit slow response (bank 2 sensor 3).

This code is set when the PCM detects a slow response from the oxygen sensor on Bank 2, Sensor 3. This may be caused by a faulty sensor, wiring issue, or engine problem.
If the code is set due to a faulty sensor, the sensor will need to be replaced. If the code is set due to a wiring issue, the wiring will need to be checked and repaired as necessary. If the code is set due to an engine problem, the engine will need to be diagnosed and repaired.
