P0167

DTC P0167, sometimes indicated as P016700 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 heater circuit malfunction (bank 2 sensor 3).

The most common cause of this DTC is a bad heater element in the oxygen sensor. Other causes can include a wiring problem, a bad ground, or a problem with the power supply to the oxygen sensor.
The solution is to replace the oxygen sensor.

• P0167: 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3)
• P0167: O2 Sensor Heater Circuit Bank 2 Sensor 3
• P0167: O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3)
• P0167: O2 Sensor Heater Circuit
• P0167: Heated oxygen sensor (HO2S) 3, bank 2, heater control – circuit malfunction
• P0167 00: Damage in the probe heating circuit? 3 (row of cylinders 2)
• P0167 00: Heated oxygen sensor (HO2S) 3, bank 2, heater control - circuit malfunction

These codes are commonly diagnosed with error code P0167.
