P2CFCA/C Clutch Control Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P2CFC is the general fault of the output that powers the compressor clutch coil directly, unlike P0645, which covers a clutch relay. Ford is the documented user and runs it in a body module, not the PCM. Special service messages 50811 and 51380 list P2CFC, often with P0645 and P2CFD, in the HVAC module of 2020–2023 Explorer and Aviator; the cause was spread or pushed-out terminals at body control module C, so pins are checked before that module is replaced. SSM 53061 reports P2CFC in the same module on F-150 trucks of 2021–2024 and Super Duty models of 2023–2024 and says voltage left on the clutch field coil while uncommanded is no reason for a new module. Ford's OBD summaries omit the code. The compressor stays off and only warm air comes out.
