P005C B Camshaft Profile Actuator A Control Performance/Stuck Off Bank 2

Exhaust cam profile actuator A on bank 2 stuck disengaged. Same fault pattern as P003C but 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.
