P247E Exhaust Gas Temperature Out of Range (Bank 2 Sensor 3)

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.

Likely causes

Uncontrolled soot burn or too much post-injection fuel on bank 2
Probe drifted and reports values too high
Leaking injector or turbo oil leak on bank 2

Symptoms

  • Warning lamp on, regeneration may be aborted
  • Reduced power to protect the aftertreatment
