P0CFCControl Pilot Charging Switch A Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- With P0CFC the module sees the circuit of charging switch A, which places the charge request on the pilot line, change state erratically: the signal toggles briefly or vanishes for moments, whereas lasting faults would set P0CF8, P0CFA or P0CFB. Likely triggers are a loose pin, corrosion in the charge inlet or module connector, or a chafed wire that loses contact only under vibration or temperature change. No manufacturer documents this code publicly; it follows the pattern of the pilot codes, and Ford's P0CF7 bulletins show how an insufficiently secured plug can produce such dropouts on the pilot itself. CARB requires plug-in vehicles to monitor the charging system. Because each lost charge request makes the station switch off, sessions are interrupted repeatedly and may restart on their own.
