P276FElectric/Auxiliary Transmission Fluid Pump B Motor Current High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- 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.
