What P247F means
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.
P247F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P247F
- Engine warning lamp lit
- Regeneration blocked or power limited
Common causes of P247F
- PossibleOverloaded particulate filter burning off too fast
- PossibleProbe ageing with readings drifting upwards
- Less likelyProbe swapped with another position after a repair
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P247F 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). |
| 7F | The exact fault in that area. |
What to do next
- Note P247F 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 P247F
What does P247F mean?
P247F means "Exhaust Gas Temperature Out of Range (Bank 2 Sensor 4)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P247F?
Drive gently and only to a workshop. With P247F the car can go into limp mode (reduced power) to protect itself.
Will P247F fail an emissions test?
Yes, it can. P247F 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 P247F to fix?
Difficulty: hard. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P247F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
