P2CF5Hybrid/EV Battery Pack Coolant Pump B Stuck/Stalled
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2CF5 means battery coolant pump B does not turn at all although it is commanded and powered: the rotor is blocked, or the pump electronics has given up after failed start attempts. A seized bearing, debris or deposits after coolant work, a failed motor winding or frozen coolant in a weak mixture are the usual suspects. Ford's 2024 summary lists the corresponding pump fault type as actuator stuck (71). No manufacturer publicly documents P2CF5; pump A's equivalent, P0CFF, appears in Ford's 2020 hybrid bulletins 20-2293/20-2345, where reprogramming the battery controller resolved it. If pump B merely runs too slowly, P2CF7 applies; overspeed or air is P2CF6. A stalled pump stops flow through its part of the battery loop, so expect power limits, slower charging and a warning lamp.
- What you may notice
- Warning lamp for hybrid system or engine
- Charging slower or interrupted
- Power reduced as battery temperature rises
- Likely causes
- LikelyPump B rotor or bearing seized
- PossibleDebris or deposits jamming the impeller after coolant work
- PossiblePump motor or its electronics failed
- RareCoolant frozen due to insufficient antifreeze
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
