You are looking at a issue with the turbocharger actuator. If the code does set as a hard fault, access the turbocharger actuator 4 wire connector. Check the Green/White wire for full battery voltage from fuse #74 20A in the Battery Junction Box. Also check the Black/Yellow wire for a good ground. Repair either circuit as needed. If the power and ground are OK, check the bus wires from the actuator to the PCM. These are: A) White/Blue wire, pin 3 of actuator, pin 34 of C1232B (58 terminal connector closest to the Right Hand fenderat Powertrain Control Module B) White wire, pin 4 of actuator, pin 47 of C1232B at PCM. Check both wires for open circuit, continuity to ground or to each other and repair as needed. If all of the actuator wires test OK, have an assistant monitor the actuator operation when cycling the key. The actuator will normally sweep one time when turning the key on. If this does not happen and all wires are OK, check for anything mechanically binding in the turbocharger. Repair as needed. If everything tests OK, replace the turbocharger actuator.
