What P247D means
P247D applies to the second probe on bank 2, by analogy with P2479 normally downstream of that bank's oxidation catalyst, where the heat released by burning fuel during a regeneration is measured. It is set when the reported temperature leaves the plausible window, in practice mostly on the high side. There is no public maker document for P247D; the closest reference is Ford's 2015 diesel summary, which uses P2479 for the bank 1 position with a limit of about 1150 °C. CARB asks for out-of-range and rationality checks on such inputs. A one-sided hot reading on bank 2 often means that bank receives more fuel, while a probe that reads hot even when cold is simply faulty.
P247D 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 P247D
- MIL on
- Regeneration cancelled
- Bank 2 probe 2 differs from its bank 1 twin
Common causes of P247D
- Most likelyToo much heat in the bank 2 catalyst during regeneration
- PossibleProbe reading high even on a cold engine
- Less likelyLeaking injector 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 P247D 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). |
| 7D | The exact fault in that area. |
What to do next
- Note P247D 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 P247D
What does P247D mean?
P247D means "Exhaust Gas Temperature Out of Range (Bank 2 Sensor 2)". P247D applies to the second probe on bank 2, by analogy with P2479 normally downstream of that bank's oxidation catalyst, where the heat released by burning fuel during a regeneration is measured. It is a generic code, so it means the same on every make.
Is it safe to drive with P247D?
Drive gently and only to a workshop. With P247D the car can go into limp mode (reduced power) to protect itself.
Will P247D fail an emissions test?
Yes, it can. P247D 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 P247D to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P247D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
