P0167O2 Sensor Heater Circuit Bank 2 Sensor 3
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Sensor 3 on bank 2 is a switching oxygen sensor behind a second converter or converter brick. It is rare – documented for Jaguar Land Rover's supercharged V6 and V8 (2013–2016), where it is the 'post-cat' sensor of the second bank, and for Ford systems that monitor part of the converter volume. P0167 concerns its heater. Ford checks the driver voltage continuously and the heater current once per drive cycle when the sensor is estimated above about 120 °C and has heated for 30 s; below 0.22–0.55 A (depending on sensor type) or above 3 A is a fault, and the heater resistance has its own code (P0061). Jaguar Land Rover lists P0167 for its post-cat sensor of the second bank. A cold sensor can lead to P0165/P0166. When it fails, the downstream evaluation of that converter is suspended; there is no limp mode.
- What you may notice
- Check engine light on (usually after two drive cycles)
- P0165/P0166 may follow
- Usually no noticeable change in driving
- Likely causes
- LikelyHeater element burnt out
- PossibleHeater wiring, connector or fuse
- RareShort circuit (current above 3 A)
- RareEngine module driver or software (Jaguar Land Rover)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
