What causes cruise control to surge?
When I have the Cruise Control on between 60-66 mph – the engine surges between 2300 and 3700 RPM While driving on flat level highway. This commonly occurs due to the fact that this engine is underpowered. The smaller engine in your vehicle has a problem maintaining speed which causes this fluctuation.
Does the throttle position sensor affect cruise control?
The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage.
What does a cruise control module do?
When you “Set” cruising speed, the cruise control module (CCM) records the current speed, then takes control of the throttle body to maintain vehicle speed. When vehicle speed increases or decreases (due to wind or hills, for example), the CCM decreases or increases throttle body opening accordingly.
What fuse controls cruise control?
The cruise control fuse is normally found in the fuse panel located below the steering wheel. Remove the cover of the fuse panel and locate the fuse for the cruise control using the fuse diagram on the fuse panel.
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.
What happens if the cruise control reservoir fails?
Another symptom of a problem with the cruise control reservoir is a cruise control system that simply cannot maintain speed. If the cruise control vacuum reservoir fails, the cruise control system will be left without its necessary vacuum reserve, and as a result, will not be able to hold the vehicle at the set speed or rate of acceleration. 3.
Why is the vacuum important to the cruise control system?
As the cruise control vacuum reservoir holds vacuum for the cruise control system so that it may operate properly even when engine vacuum is low, it is very important to the proper operation of the cruise control system, and any issues with it can cause problems for the entire system.
