TURBOCHARGER SYSTEM
Intake (Induction)
E: WASTEGATE CONTROL SOLENOID VALVE
The wastegate control solenoid valve switches the intake air pressure passages to the wastegate
controller in response to signals from the ECM. When the solenoid valve is closed, the intake air
pressure upstream of the turbocharger unit is applied to the wastegate controller. When the sole-
noid valve is opened, the intake air pressure downstream of the turbocharger unit (supercharged
air pressure) is applied to the wastegate controller.
