P2C75Active Grille Air Shutter Module C Over Temperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Engine warning lamp, often intermittent
- Shutter C stops moving until the module has cooled down
- Likely causes
- LikelyFlap frozen, jammed or bent so the motor works against a stop
- PossiblePartly shorted motor winding drawing excess current
- PossibleInternal fault of the actuator electronics
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
