P002CB Camshaft Profile Actuator A Control Circuit High Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- A camshaft profile actuator switches the exhaust camshaft (camshaft B) on bank 1 between two or more fixed cam profiles with different valve lift and duration, for example by shifting a cam piece axially or by locking rocker arms or tappets with oil pressure. Unlike a camshaft phaser it does not shift the timing continuously. The second letter "A" in the title numbers the actuator on this camshaft. This code is set when the control circuit reads too high, typically because of a short to battery voltage or overcurrent in the output stage. The engine usually stays on one profile, typically the base profile with low lift. Some manufacturers report these faults with their own codes instead.
- What you may notice
- Check engine light on
- Less power at high engine speed because the profile does not switch
- Higher consumption or uneven part-load running, depending on the profile
- Engine speed may be limited
- Likely causes
- LikelyControl wire shorted to battery voltage
- PossibleActuator coil shorted, causing overcurrent
- PossibleConnector corroded or contaminated with oil
- RareOutput driver in the engine control module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €50 – €500
