What P276F means
P276F is stored when the motor of auxiliary pump B pulls more current than the module allows. Excess draw points to a motor that is working too hard or is electrically damaged: a dragging bearing, debris or varnish in the pump, very cold thick fluid, a partially shorted winding or a chafed lead touching ground. No manufacturer documents P276F publicly. Ford's 2024 OBD summary shows the matching pump A logic for the 10R60/10R80 and 8F57 transmissions, where the pump itself reports an over-current that the TCM files as P0C28 (UDS P0C26_19). To protect wiring and electronics, most controllers then switch the pump off, so the vehicle loses the functions that depend on it. If the motor stops completely, P277C is the more specific code; P276E is the low-current sibling.

- Clears after repairWhen cleared with a scanner
Symptoms of P276F
- Warning lamp with transmission fault message
- Stop-start function disabled
- Possible whine or rattle from the pump area
Common causes of P276F
- Most likelyDragging bearing or debris inside pump B
- PossiblePartially shorted motor winding
- PossibleChafed pump lead shorting to ground
- Less likelyContaminated or wrong-viscosity transmission fluid
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P276F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 6F | The exact fault in that area. |
What to do next
- Note P276F 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 P276F
What does P276F mean?
P276F means "Electric/Auxiliary Transmission Fluid Pump B Motor Current High". P276F is stored when the motor of auxiliary pump B pulls more current than the module allows. It is a generic code, so it means the same on every make.
Is it safe to drive with P276F?
Drive gently and only to a workshop. With P276F the car can go into limp mode (reduced power) to protect itself.
Will P276F fail an emissions test?
P276F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P276F to fix?
Difficulty: hard. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P276F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
