P2C0DA Camshaft Profile Actuator Position Sensor C Circuit 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
- Position sensor C is the third of the Hall feedback elements on the intake side of bank 1; on GM's L3B it sits in intake actuator 3 and is named intake Hall sensor 3. That engine has four intake and two exhaust profile actuators, so a fourth intake feedback exists beyond the J2012 letters and GM handles it with P30B0 to P30B3. P2C0D is the open-circuit check for sensor C: output on, at least 200 kilohms from signal to ground, four of five samples at over 11 V, key in crank or run, Type A with MIL on the first trip (19OBDG03D, 25OBDG03B). Both PIT5677 and its successor 21-NA-149 from GM list P2C0D for 2019 to 2021 L3B trucks with chafed engine harnesses. As long as sensor C reports nothing, the ECM blocks lift changes.
- What you may notice
- Check engine light on in the first trip
- No lift switching, no cylinder deactivation
- Further codes, reduced power or no start if the harness is damaged
- Likely causes
- LikelyHarness rubbed through over the camshaft carrier, wire broken (GM L3B bulletins)
- PossibleConnector on actuator 3 loose, damaged or corroded
- PossibleOpen circuit inside actuator 3 or its Hall element
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
