Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
The position of the turbocharger vanes is controlled by the engine control module (ECM). The ECM utilizes a turbocharger vane control solenoid valve and a turbocharger vane position sensor to control the turbocharger vanes. The ECM will vary the boost dependant upon the load requirements of the engine. The vane control solenoid valve has 2 circuits, a high control circuit and a low control circuit. The ECM uses a pulse width modulation on the control circuits to open and control the solenoid valve.
