P002E — B Camshaft Profile Actuator A Control Circuit Low Bank 2
Low control voltage at the exhaust cam profile actuator (profile A, bank 2). Same as P002B on bank 2. The cam phaser actuator adjusts intake/exhaust timing under load — a stuck or slow phaser kills mid-rpm torque and can throw correlation codes between cam and crank.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Cam profile actuator exhaust
- Actuator wiring
Possible causes to check

- Power loss especially in mid-rpm range
- Possible rough idle or stalling
- Increased fuel consumption
