What P2C0E means
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.
P2C0E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C0E
- MIL comes on immediately
- Lift switching suspended, engine runs on one profile
- Occasional ticking or uneven running if a sleeve sits halfway
Common causes of P2C0E
- Most 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
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C0E 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. |
| 0E | The exact fault in that area. |
What to do next
- Note P2C0E 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 P2C0E
What does P2C0E mean?
P2C0E means "A Camshaft Profile Actuator Position Sensor C Range/Performance Bank 1". P2C0E is the plausibility test for the feedback of the third intake actuator on bank 1. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C0E?
Drive gently and only to a workshop. With P2C0E the car can go into limp mode (reduced power) to protect itself.
Will P2C0E fail an emissions test?
Yes, it can. P2C0E 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 P2C0E to fix?
Difficulty: medium. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P2C0E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
