P2BC3Charge Air Cooler Coolant Pump A Control Module Overtemperature
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The control electronics of an electric coolant pump sit inside the pump body and are cooled by the liquid flowing through it. P2BC3 means the electronics of charge air cooler pump A report a temperature above their limit. Far more often than a defective board, the reason is a low coolant level, air trapped in the pump after service, a partly blocked impeller drawing extra current, or a mounting spot exposed to engine heat. No manufacturer documents P2BC3 publicly. Ford's 2019 hybrid OBD summary shows how such a check works on its LIN-connected engine coolant pump (P26D2): the pump sends its module temperature and the PCM flags a value above 130 °C; the 2024 summary lists the same overtemperature type for the auxiliary pumps. The pump then derates or stops, and charge air temperature rises.
- What you may notice
- Check engine light or engine warning message
- Pump runs slower or switches off, especially in hot weather
- Hot charge air and reduced power
- Likely causes
- LikelyLow coolant level or air trapped in the low-temperature loop
- PossiblePartly blocked impeller or worn bearing raising motor current
- PossibleFault in the pump's integrated electronics
- RareMissing heat shield or pump placed close to hot engine parts
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
