P247E code meaning
Exhaust Gas Temperature Out of Range (Bank 2 Sensor 3)
Powertrain system Generic code P24xx codes Check engine light
What P247E means
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.
P247E 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 P247E
- Warning lamp on, regeneration may be aborted
- Reduced power to protect the aftertreatment
Common causes of P247E
- PossibleUncontrolled soot burn or too much post-injection fuel on bank 2
- PossibleProbe drifted and reports values too high
- Less likelyLeaking injector or turbo oil leak on bank 2
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P247E 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). |
| 7E | The exact fault in that area. |
What to do next
- Note P247E 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 P247E
What does P247E mean?
P247E means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P247E?
Drive gently and only to a workshop. With P247E the car can go into limp mode (reduced power) to protect itself.
Will P247E fail an emissions test?
Yes, it can. P247E 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 P247E to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P247E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
