What P2C0D means
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.
P2C0D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C0D
- 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
Common causes of P2C0D
- Most 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
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C0D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 0D | The exact fault in that area. |
What to do next
- Note P2C0D and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2C0D
What does P2C0D mean?
P2C0D means "A Camshaft Profile Actuator Position Sensor C Circuit Bank 1". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C0D?
Drive gently and only to a workshop. With P2C0D the car can go into limp mode (reduced power) to protect itself.
Will P2C0D fail an emissions test?
Yes, it can. P2C0D is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2C0D to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2C0D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
