P0CC2Drive Motor A Coolant Pump Control Circuit Range/Performance
- 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
- 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.
- What you may notice
- Check-engine lamp
- Electric assist reduced as the motor generator heats up
- Likely causes
- LikelyAir in the motor generator cooling loop, often after service
- PossibleWorn or seized pump impeller
- PossibleLow coolant level or kinked or blocked hose
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
