Ford Ranger/Explorer/Mountaineer 1991-1999

Electronic Systems


See Figure 1

The electronic cruise control system consists of the following components:

Control switches
Servo/control unit (throttle actuator)
Speed sensor
Stoplamp and deactivator switches

The throttle actuator/control unit is mounted in the engine compartment and is connected to the throttle linkage with an actuator cable. The control unit regulates the throttle actuator to keep the requested speed. When the brake pedal is depressed, an electrical signal from the stoplamp and deactivator switches return the system to stand-by mode. This system operates independently of engine vacuum, therefore no vacuum lines are required.
