P2CFEA/C Clutch Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2CFE reports a clutch coil output that sits higher than it should, typically because the line touches a battery feed. Then the clutch may stay energized after the module switches off, so the compressor keeps running and can ice the evaporator; a low-side driver instead shuts down and the clutch never engages. No manufacturer documents P2CFE publicly. Ford, which drives the clutch from a body module, publishes only P2CFC and P2CFD; its SSM 53061 notes that voltage remaining on the field coil circuit when not commanded is no reason to replace that module, which shows how such a high reading is assessed. The relay counterpart P0647 is described for the 2011 Saab 9-5 as a short to voltage. CARB requires monitoring of A/C components where they alter engine control.
- What you may notice
- Compressor runs even with A/C switched off
- Iced evaporator, weak airflow after a while
- Alternatively no cooling at all if the driver shuts down
- Likely causes
- LikelyClutch control wire shorted to a battery-powered circuit
- PossibleOutput stage in the module stuck switched on
- RareMoisture bridging pins in the compressor or module connector
- Repair
- Medium · Usually a job for a workshop.Typical cost: €50 – €600
