P2C0EA Camshaft Profile Actuator Position Sensor C Range/Performance Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2C0E is the plausibility test for the feedback of the third intake actuator on bank 1. On the L3B, the ECM classifies each shift by the Hall signal of that actuator: extending when it drops below 55, fully extended under 45, retracted when it rises above 68 again. The code is set when a commanded shift does not produce this pattern, or when activity appears without any command. GM requires 4 faulty readings in 5 with the engine running, supply above 11 V and no active crank or camshaft sensor faults, and lights the MIL at once as Type A (19OBDG03D, 25OBDG03B). Unlike most of its siblings, P2C0E is not named in GM's harness bulletins; a mechanically sluggish actuator 3 or a damaged sleeve groove is the usual suspect. CARB demands detection of wrong-profile operation.
- What you may notice
- MIL comes on immediately
- Lift switching suspended, engine runs on one profile
- Occasional ticking or uneven running if a sleeve sits halfway
- Likely causes
- LikelyPin of actuator 3 sticking or responding late
- PossibleDamaged groove or detent on the cam sleeve served by actuator 3
- PossibleOld or wrong-grade oil slowing the pin
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
