P2C4D Clutch Actuator Position Sensor Circuit High
P2C4D is set when the clutch actuator position signal rises above its upper limit. Ford lists it beside P2C4C in its 2020–2023 and 2024 gasoline OBD summaries: continuous monitoring, under one second to detect, and in 2024 reported as P2C4A with failure type 12. Ford does not state whether the MIL comes on. A high reading typically indicates an open sensor ground, a signal wire touching a supply voltage or a sensor whose output has gone to the rail; with three-wire Hall sensors an interrupted ground is a frequent cause because the signal then floats up to the reference. Unlike P2C4B the voltage itself is implausible, not just the position it represents. As with the low fault, start-stop features that rely on knowing the clutch state are switched off until the circuit is repaired.
Likely causes
Symptoms
- Stop-start or stop-in-gear unavailable
- Warning lamp or message
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
