Theory Of Operation
WARNING: This page is about a different variant/trim than selected.
The Variable Geometry Turbocharger (VGT) is electronically actuated by the Turbo actuator. The Turbo Actuator is a smart device that receives the commanded vane position from the Powertrain Control Module (PCM) via a PWM signal. The Turbo actuator sends a feedback vane position to the PCM using the Private CAN BUS. If the delta between the commanded Turbo position and feedback turbo position is greater than a calibrated delta for a calibrated amount of time a fault will set.
