P247FExhaust Gas Temperature Out of Range (Bank 2 Sensor 4)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P247F flags an unacceptable reading from the fourth exhaust temperature probe of bank 2, the position that on most layouts sits behind the particulate filter. A genuine reading near the limit there means heat is leaving the filter, which points to a runaway regeneration. No manufacturer documents P247F publicly. The bank 1 counterpart P247B appears only in Ford's 2015 diesel summary, which trips it once the probe exceeds roughly 1150 °C; by 2023 Ford checked probe 4 against a temperature model (P246E) instead. CARB demands range and rationality monitoring for such inputs. Before the probe is replaced, compare it with the bank 1 probe 4 and inspect the filter, because a cracked substrate can follow repeated overheating.
- What you may notice

- RareProbe swapped with another position after a repair
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
