What P247C means
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.
P247C at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P247C
- MIL on
- Reduced power to protect the exhaust
- Bank 2 probe reads clearly above bank 1
Common causes of P247C
- Most likelyBank 2 running hot from extra fuel or a faulty injector
- PossibleBank 2 probe 1 reading too high
- Less likelyAir shortage on bank 2 from a boost leak or turbo fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P247C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 7C | The exact fault in that area. |
What to do next
- Note P247C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P247C
What does P247C mean?
P247C means "Exhaust Gas Temperature Out of Range (Bank 2 Sensor 1)". 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 is a generic code, so it means the same on every make.
Is it safe to drive with P247C?
Drive gently and only to a workshop. With P247C the car can go into limp mode (reduced power) to protect itself.
Will P247C fail an emissions test?
Yes, it can. P247C is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P247C to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P247C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
