This category on the website [ Solenoids Modules and Wiring ] we are giving you all of the information related to the individual parts in the Buick Turbo Regal, along with the associated wiring, connector plugs, etc.
.
VEHICLE APPLICATION:
Buick Regal, T-Type, Turbo T, Limited, Grand National, GNX
SOLENOID NAME:
Wastegate Control Solenoid
PURPOSE OF SOLENOID:
The pulse action of the solenoid is to limit boost at a calculated amount (determined by the computer).
The wastegate solenoid closes when engine knock is detected. It is pulsed more when third gear is detected to help control the boost creep.
Under certain conditions, it will also regulate the movement of the wastegate actuator.
TURNS ON-OFF / FUNCTIONS / USED WHEN:
constantly monitoring while engine is running.
ECM (or chip) determines when to use this.
LOCATION IN VEHICLE:
passenger side of car, attached to valve cover (1986-1987)
rear of engine (1984-1985)
