P2BC2Charge Air Cooler Coolant Pump A Supply Voltage Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2BC2 points to the power feed of charge air cooler pump A: the pump or its controller sees a supply that is missing or outside its working window. Typical causes are a blown fuse, a relay with burnt contacts, a broken or corroded feed or ground wire, or a water-damaged plug; a weak battery can contribute. No manufacturer documents P2BC2 publicly. Ford's 2024 OBD summary shows the same fault type on its smart auxiliary coolant pumps: the pump driver flags a supply outside its permitted range (P2B9D for pump A), checked continuously from 11 V battery voltage and logged after five seconds. CARB requires charge air cooler systems and their electrical components to be monitored. Without a proper supply the pump stops, the charge air warms up and the engine may limit power. A pump that is powered but blocked is P2BC1.

- RareWeak battery or charging fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
