P2C0FA Camshaft Profile Actuator Position Sensor C Circuit Low 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
- With P2C0F the ECM sees the position sensor C circuit of bank 1, the Hall feedback in the third intake actuator, connected to ground. In GM's L3B tables the test runs while the output is commanded on and looks for a signal-to-ground resistance not above 0.5 ohm; after 4 failures in 5 samples at more than 11 V the code is stored as Type A and the MIL lights at once (19OBDG03D; the 2025 table 25OBDG03B keeps the same limit). Of GM's harness bulletins, only the keyword section of PIT5677 and 21-NA-149 mentions P2C0F, while their main lists carry the open and high codes of this sensor. A pinched wire against the cylinder head or a shorted actuator is the probable cause; lift switching remains blocked. Open: P2C0D, high: P2C10.
- What you may notice
- Check engine light comes on during the first drive
- Engine no longer switches cam profile or deactivates cylinders
- Likely causes

- PossibleInternal ground short in actuator 3
- RareContaminated or damaged connector pins
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
