P2C4DClutch Actuator Position Sensor Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
