P0CF7 Control Pilot Circuit Intermittent/Erratic

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

This code stands for a pilot signal that comes and goes or jumps between levels, typically from a loose contact in the charge inlet, a plug that is not fully latched or interference on the line. Ford documents P0CF7 on the 2021-2022 Mustang Mach-E and the 2022 e-Transit, logged by the SOBDM (secondary OBD module A), and on the 2022 F-150 Lightning by the same unit, there called BCCM, the charger control module. The bulletins link it to a charge status indicator flashing red, often alongside P0A7F from the battery controller; for the Mach-E an EVSE plug that is not properly secured is named as the trigger, and for both models the fix is new SOBDM/BCCM software. Steady opens, shorts and plausibility faults use P0CF3 to P0CF6. Charging stops now and then or is aborted.

Likely causes

Charger module software reacting too sensitively (Ford SOBDM/BCCM reprogramming)
Charging plug not fully seated or latched in the inlet
Worn or loose pilot contact in the inlet or on the charging cable
Charging station producing an unstable pilot signal

Symptoms

  • Charge status indicator flashing red (Ford)
  • Charging stops intermittently
  • Additional warning lamp with related codes such as P0A7F
