P0162O2 Sensor 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. P0162 is the general circuit code of this sensor, the counterpart of P0142. Jaguar Land Rover assigns the code to that sensor and names software (fixed by reconfiguring the engine module) and water-induced thermal shock as causes; no thresholds are published for sensor 3, so the logic follows the sensor 2 checks. The previous obdex titles from P0162 to P0165 were shifted by one position; P0162 had carried the heater title of P0161. 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)
- Catalyst readiness incomplete
- Usually no noticeable change in driving
- Likely causes
- LikelySensor faulty or damaged by thermal shock
- PossibleWiring or connector under the car damaged
- PossibleEngine module software (Jaguar Land Rover)
- RareExhaust leak ahead of the sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €60 – €300
