Speed Control Actuator

WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

The speed control module provides signals to the actuator. The actuator moves the throttle by means of an internal geartrain and an actuator cable. The vehicle speed sensor generates the reference signal that the actuator compares to the set speed selected by the driver. If a discrepancy exists the speed control actuator will adjust the throttle, correcting the vehicle speed.

The speed control actuator is mounted behind the LH headlamp. The speed control actuator incorporates the following components:

An electronic module
An actuator consisting of a stepper motor and geartrain electromagnetic coupling and reduction gearing

The speed control actuator evaluates the incoming speed signal from the speed sensor and switch inputs. It adjusts the throttle to maintain a constant vehicle speed.

If the clutch pedal (vehicles with manual transaxle) or the brake pedal is pressed, the speed control actuator deactivates the speed control. The actuator will enter a stand-by mode.
