How does a cruise control module detect speed?
The only way your cruise control module is going to know how fast the vehicle is moving is if the vehicle speed sensors feed this information to it. If the module cannot detect the speed because of faulty speed sensors, then the cruise control system will automatically deactivate.
What do you need to know about cruise control?
Basic cruise control systems still require the driver to pay attention to changing road and traffic conditions. Adaptive cruise control systems, sometimes called “smart” cruise, use radar or laser detection to maintain safe distances from vehicles ahead.

What happens when a cruise control vacuum fails?
If the cruise control vacuum reservoir fails, the cruise control system will be left without the vacuum it requires to hold the vehicle at a steady speed or rate of acceleration. The cruise control may still try to hold the vehicle at a certain speed, however, it will eventually run low on vacuum which will cause the vehicle to slow.
How does a cruise control system work in a car?
Early systems used a vacuum motor and cable, but these eventually changed over to electric motors. Most recently, with the development of drive-by-wire or electronic throttle control systems (ETCS), cruise control is built into the engine control module (ECM), which controls the throttle body electronically.
What to do if your Cruise Control is not working?
It supplies the cruise control system with the vacuum necessary for it to operate, and without it, the system cannot function. For this reason, if you suspect that your vehicle may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic.
