Turbocharger Vane Position Control Solenoid Valve
WARNING: This page is about a different variant/trim than selected.
The vane position control solenoid valve (2) works in conjunction with oil pressure to control the turbocharger vanes. The solenoid valve has two circuits; a low control circuit and a high control circuit. The engine control module (ECM) uses a pulse width modulation on both control circuits to control the solenoid valve. The ECM will control the solenoid valve to allow the engine oil pressure (EOP) to move a piston (6). This piston rotates the unison ring, thus controlling the engine boost dependant upon engine load.
