P0CC0Drive Motor A Coolant Temperature Sensor Circuit Intermittent
- 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
- 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.
