Variable Geometry Turbocharger (VGT) Vane Actuator

WARNING: This page is about a different variant/trim than selected.

The VGT vane actuator is located on the side of the turbocharger.

The actuator comprises a 12V DC motor which operates a worm drive to move the actuator arm to adjust the vane position.

The PCM controls the output to the vane actuator motor using a Pulse width modulation (PWM) output.

The motor also contains an angular position sensor. The PCM outputs a 5V reference voltage to the position sensor and the sensor returns a ground and a signal proportional to the actuator position.
