When you use the cruise control to maintain a set speed, how does it know what speed it is maintaining? Long gone are the days of cruise control systems mechanically holding the throttle in a certain position with a cable or chain. Those systems were prone to failure if the cable came loose or slipped, or if it got snagged on another component nearby under the hood. Now, the cruise control is set electronically.
The cruise control utilizes the vehicle speed sensor mounted on the transmission to monitor your vehicle’s actual speed and adjusts its output based on that information. The vehicle speed sensor actively reads the transmission’s revolutions in real time to determine vehicle speed. If the cruise control speed sensor reads incorrectly, intermittently, or not at all, the cruise control will not operate in the proper manner. It may set but cancel on its own if it cannot see a speed signal, or it may not set at all. It is also possible that the speed will fluctuate greatly when it is set, and the engine will surge at times to undesired speeds.
It is necessary to have a mechanic diagnose and repair the cruise control system. Nearly all manufacturers have proprietary information so they are able to restrict access to the speed sensor data only to those shops with the correct diagnostic tools. If you are experiencing a cruise control problem, have one of our expert technicians diagnose and repair the system.
The cruise control is an accessory device and is not integral to your vehicle’s safe operation. Have the cruise control repaired at your earliest convenience.
