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.
Medium severity. Can I keep driving?Yes, you can normally drive in moderation, but get it repaired soon: you will use more fuel and the catalytic converter can be damaged over time.
Bank 2 is the side without cylinder 1, so it only exists on V or boxer engines.
Symptoms
- Check engine light on (usually after two drive cycles)
- P0165/P0166 may follow
- Usually no noticeable change in driving
Most likely causes
- Heater element burnt out
- Heater wiring, connector or fuse
- Short circuit (current above 3 A)
- Engine module driver or software (Jaguar Land Rover)
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: easy
- It affects emissions.
What each character of P0167 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 1: Air and fuel
- 67: Specific fault in that system
Frequently asked questions
