P247CExhaust Gas Temperature Out of Range (Bank 2 Sensor 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P247C is the bank 2 counterpart of P2478: the first exhaust probe on the second cylinder bank reports a temperature outside its permitted window, typically next to the turbine outlet or catalyst inlet of that bank. It needs a V engine with separate exhaust paths and its own probe per bank. No maker documents P247C in public material; Ford's 2015 diesels with their single exhaust stream use only the bank 1 numbers, with a high-side limit of about 1150 °C, and Volkswagen's 2014 2.0L TDI checks the target-to-actual gap. Comparing both banks helps: if only bank 2 runs hot, look at that bank's injectors, turbo and air supply before replacing the probe.
- What you may notice
- MIL on
- Reduced power to protect the exhaust
- Bank 2 probe reads clearly above bank 1
- Likely causes
- LikelyBank 2 running hot from extra fuel or a faulty injector
- PossibleBank 2 probe 1 reading too high
- RareAir shortage on bank 2 from a boost leak or turbo fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
