B Camshaft Profile Actuator A Control Circuit High Bank 1
What it means
P002C means the control circuit for the bank 1 "B" camshaft profile actuator — the solenoid that switches the valve-lift/profile stage on engines with variable-lift systems — is reading an abnormally high voltage, indicating a short to voltage or a failed solenoid. With the profile actuator unable to switch correctly, the engine may idle roughly and lose power. It's an electrical circuit fault, not a mechanical no-start.
Can I keep driving? Usually drivable — the variable-lift/profile stage may be stuck, causing rough idle or reduced power; it won't strand you, but performance and emissions suffer.
Common symptoms
What you'll notice
- Check-engine light on
- Unstable or rough idle
- Reduced power and poor acceleration
- Slightly worse fuel economy
Common causes
Most likely first
- Short-to-voltage in the camshaft profile actuator control circuit (high signal)Likely
- Failed 'B' camshaft profile/lift control solenoid or actuatorCommon
- Damaged or chafed wiring in the actuator circuitCommon
- Corroded or loose connector at the solenoidLess often
- Faulty engine control module (ECM), rarelyLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and locate the bank 1 'B' camshaft profile actuator solenoid.
- Inspect the control wiring and connector for a short to voltage, chafing, or corrosion — a 'circuit high' code means the signal line is reading too high.
- Measure the solenoid resistance and compare to spec; replace it if out of range.
- Repair any wiring shorts, then clear the code and confirm the actuator responds.
- If circuit and solenoid test good, evaluate the ECM.
