Hi, the Motor for Intake Manifold Flap V157 you will find once stripped is partially seized causing this fault code to be flagged, the power supply to the motor is fused forgot the location number but you will find it blown due to the excessive current being drawn from V157, the fuse also links to the Coolant Fan Control 1 which see is also open circuit. Hope this helps.
