B Camshaft Profile Actuator A Control Stuck On Bank 1
Exhaust cam profile actuator A on bank 1 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.
