P247EExhaust Gas Temperature Out of Range (Bank 2 Sensor 3)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P247E does not question the wiring but the value itself: the third exhaust probe on cylinder bank 2 reports a temperature the engine control unit will not accept, in practice mostly an implausibly hot one. The code only makes sense on a V engine whose two banks keep separate exhaust paths up to the third measuring point. No maker publishes P247E; the bank 1 twin P247A is used by Ford's 2015 diesels with a high-side limit of about 1150 °C and by Volkswagen's 2014 Touareg V6 TDI, which flags a target-to-actual gap above 200 K. CARB requires such inputs to be checked for range and plausibility. Look at the bank 2 regeneration and fuelling first; a probe that reads hot at a cold start is simply faulty.
- What you may notice
- Warning lamp on, regeneration may be aborted
- Reduced power to protect the aftertreatment
- Likely causes
- PossibleUncontrolled soot burn or too much post-injection fuel on bank 2
- PossibleProbe drifted and reports values too high
- RareLeaking injector or turbo oil leak on bank 2
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
