What P0CC0 means
P0CC0 is meant for a coolant temperature signal of drive motor A that drops out or jumps for short moments. No manufacturer documents this code publicly. GM's 2013 eAssist table, the most detailed public source for this sensor, monitors it only with P0CBD for plausibility and P0CBE/P0CBF for out-of-range values; Volvo and Polestar report P0CBC with failure type 62. CARB section (e)(15.2.1) asks for circuit and range faults of inputs to be detected, and (e)(15.2.3)(B)(ii) extends this to the cooling of the inverter. A sporadic code typically stems from a loose terminal, a chafed wire that touches metal only on bumps, or water in the connector. Since the reading normally recovers, the lamp may go out again; live data recorded during a drive help to catch the moment of the fault.
P0CC0 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0CC0
- Warning lamp that appears and disappears
- Jumping coolant temperature value in live data
Common causes of P0CC0
- Most likelyLoose or spread terminal in the sensor connector
- PossibleChafed wire making contact only on bumps
- Less likelyMoisture in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC0 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. |
| C0 | The exact fault in that area. |
What to do next
- Note P0CC0 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 P0CC0
What does P0CC0 mean?
P0CC0 means "Drive Motor A Coolant Temperature Sensor Circuit Intermittent". P0CC0 is meant for a coolant temperature signal of drive motor A that drops out or jumps for short moments. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC0?
Drive gently and only to a workshop. With P0CC0 the car can go into limp mode (reduced power) to protect itself.
Will P0CC0 fail an emissions test?
Yes, it can. P0CC0 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 P0CC0 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0CC0 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.
