What P0167 means
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.
P0167 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0167
- Check engine light on (usually after two drive cycles)
- P0165/P0166 may follow
- Usually no noticeable change in driving
Common causes of P0167
- Most likelyHeater element burnt out
- PossibleHeater wiring, connector or fuse
- Less likelyShort circuit (current above 3 A)
- Less likelyEngine module driver or software (Jaguar Land Rover)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0167 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1 | Area: fuel and air metering. |
| 67 | The exact fault in that area. |
What to do next
- Note P0167 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0167
What does P0167 mean?
P0167 means "O2 Sensor Heater Circuit Bank 2 Sensor 3". Sensor 3 on bank 2 is a switching oxygen sensor behind a second converter or converter brick. It is a generic code, so it means the same on every make.
Is it safe to drive with P0167?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0167 fail an emissions test?
Yes, it can. P0167 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0167 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0167 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
