P005D — B Camshaft Profile Actuator A Control Stuck On Bank 2
Exhaust cam profile actuator A on bank 2 stuck engaged. Same fault pattern as P003D on the exhaust cam. 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
- Oil control valve
