P25CD Intake Camshaft Actuator Park Lock Control Circuit / Open Bank 2
The controller cannot drive the park-lock pin that secures the intake camshaft phaser on bank 2 in its base position at engine off. Without the lock, the next start can suffer poor combustion or rough idle until the phaser builds oil pressure.
