P247D Exhaust Gas Temperature Out of Range (Bank 2 Sensor 2)

P247D applies to the second probe on bank 2, by analogy with P2479 normally downstream of that bank's oxidation catalyst, where the heat released by burning fuel during a regeneration is measured. It is set when the reported temperature leaves the plausible window, in practice mostly on the high side. There is no public maker document for P247D; the closest reference is Ford's 2015 diesel summary, which uses P2479 for the bank 1 position with a limit of about 1150 °C. CARB asks for out-of-range and rationality checks on such inputs. A one-sided hot reading on bank 2 often means that bank receives more fuel, while a probe that reads hot even when cold is simply faulty.

Likely causes

Too much heat in the bank 2 catalyst during regeneration
Probe reading high even on a cold engine
Leaking injector on bank 2

Symptoms

  • MIL on
  • Regeneration cancelled
  • Bank 2 probe 2 differs from its bank 1 twin
