What P2C68 means
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.
P2C68 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C68
- Drive system warning, check engine light
- Strongly reduced power or charging interrupted
- No pump noise when the pump is activated with a scan tool
Common causes of P2C68
- Most likelySeized bearing or impeller in pump A
- PossibleForeign matter or sludge blocking the impeller
- PossibleBurnt winding or failed pump electronics
- Less likelyCoolant frozen due to weak antifreeze
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C68 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 68 | The exact fault in that area. |
What to do next
- Note P2C68 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2C68
What does P2C68 mean?
P2C68 means "Hybrid/EV Electronics Coolant Pump A Stuck/Stalled". P2C68 means the electronics coolant pump A has power and a command, yet its rotor does not turn or stops. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C68?
Drive gently and only to a workshop. With P2C68 the car can go into limp mode (reduced power) to protect itself.
Will P2C68 fail an emissions test?
Yes, it can. P2C68 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2C68 to fix?
Difficulty: hard. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P2C68 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
