P2C68Hybrid/EV Electronics Coolant Pump A 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
- P2C68 means the electronics coolant pump A has power and a command, yet its rotor does not turn or stops. Brushless pumps notice this themselves from a failed start attempt or high current with no rotation and report it to the controller. No manufacturer publicly documents P2C68. Ford's 2024 summary shows the matching fault type 71, actuator stuck, for engine coolant pump A (P2B9C), and a GM patent detects electric coolant pump faults by comparing measured with expected current. Seized bearings, sludge or debris, frozen coolant and burnt windings are the usual causes. Without flow, inverter and charger heat up quickly, so the vehicle limits power or stops charging. Audi's e-tron bulletin shows pump circuit faults (P0CE9) together with low coolant warnings.
- What you may notice
- Drive system warning, check engine light
- Strongly reduced power or charging interrupted
- No pump noise when the pump is activated with a scan tool
- Likely causes
- LikelySeized bearing or impeller in pump A
- PossibleForeign matter or sludge blocking the impeller
- PossibleBurnt winding or failed pump electronics
- RareCoolant frozen due to weak antifreeze
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
