P2C75 Active Grille Air Shutter Module C Over Temperature

Smart grille shutter actuators carry their own driver chip and protect it by temperature. P2C75 is that self-protection for shutter C: the module reports its electronics as overheated and stops driving the motor. No manufacturer documents P2C75; the closest published logic is Ford's for shutters A and B (P05C0, P05C1): a chip junction temperature above 140 °C, confirmed after 10 s in the 2023 diesel summary and after 30 s in the 2024 petrol summary, with no further entry conditions. Heat builds when the motor keeps pulling against a frozen, jammed or bent flap, or when its winding is partly shorted; an internal fault is also possible. After cooling the flap often works again, which makes the fault look sporadic. Unlike P2C73 and P2C74, the verdict comes from the actuator's own electronics.

Likely causes

Flap frozen, jammed or bent so the motor works against a stop

Partly shorted motor winding drawing excess current

Internal fault of the actuator electronics

Symptoms

Engine warning lamp, often intermittent
Shutter C stops moving until the module has cooled down
