What Is A Cruise Control Servo? The cruise control system operates a mechanical linkage to the throttle body by using a vacuum motor called the cruise servo. This servo has a diaphragm that is moved when vacuum is applied to one side. One solenoid connects the vacuum motor to the vacuum tank and allows for more throttle position.
How does a cruise control servo work? There are two main components of the cruise control system: the controller and the servo. The controller integrates all the inputs and tells the servo how far to actuate the throttle plates. The servo does the work of moving the throttle blades to speed up the vehicle.
