P2CC0PCV Heater B Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2CC0 covers PCV heater B when its wiring passes the electrical tests but the heater does not behave as expected: current outside the plausible window, an overheated output stage, or no sign of the commanded warming. It complements the circuit codes P2CBD to P2CBF, which only detect opens and shorts. No manufacturer documents P2CC0 publicly, and the A-side code P053D is not published either; GM Europe files the closest function, an over-temperature of the heater output stage while switched on, under P052E as a Type A fault on the Saab 9-5 2.0 diesel. An FCA patent explains why the heaters matter: frozen blow-by in the make-up air line can block flow and harm the compressor wheel. Aging elements or high-resistance contacts are typical.
