What P0CC2 means
P0CC2 judges whether the pump for drive motor A actually moves coolant, not only whether its wiring is intact. GM's 2013 eAssist table 13OBDG05C infers flow from temperature: when the model predicts more than 17 °C between the jacket coolant of the motor generator and the coolant reaching the loop sensor, a running pump should make the sensor warm up quickly. If its rate of change stays at 0.25 °C per second or less 20 s after the pump was switched on, the test fails, Type B, two trips, with over 10 V supply. The check is blocked by pump circuit codes P0CC1/P0CC3/P0CC4, by the loop sensor codes P0CBD to P0CBF and by stator sensor codes P0A2B to P0A2D. A seized or air-locked pump, low coolant or a blocked hose are typical; CARB section (e)(15.2.2) requires such functional checks of output components.
P0CC2 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P0CC2
- Check-engine lamp
- Electric assist reduced as the motor generator heats up
Common causes of P0CC2
- Most likelyAir in the motor generator cooling loop, often after service
- PossibleWorn or seized pump impeller
- PossibleLow coolant level or kinked or blocked hose
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC2 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| C2 | The exact fault in that area. |
What to do next
- Note P0CC2 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 P0CC2
What does P0CC2 mean?
P0CC2 means "Drive Motor A Coolant Pump Control Circuit Range/Performance". P0CC2 judges whether the pump for drive motor A actually moves coolant, not only whether its wiring is intact. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC2?
Drive gently and only to a workshop. With P0CC2 the car can go into limp mode (reduced power) to protect itself.
Will P0CC2 fail an emissions test?
Yes, it can. P0CC2 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 P0CC2 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0CC2 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
