There's the Vehicle Speed Sensor... your cruise control is a matter of programming in the ECM.
depending on the year of the car it could be as simple as a leaking vacuum line or in newer models a bad sensor located on the motor that controls the cruise control
Yes, it can cause the cruise to surge.
A malfunction in the range sensor could cause the cruise to be inoperative.A malfunction in the range sensor could cause the cruise to be inoperative.
on the 1998 the camshaft sensor is in the distributor ,you have to change it....you have to change the whole distributor..the sensor is integrated. the crankshaft sensor is located on the block under the cruise control actuator
check fuses then refer to the speed control sensor which is on the throttle body closest to the air intake hose that controls the engine idle and speed control. Good luck.
Yes it could, if it is setting codes it will affect the cruise.
on the transmission
If it has one, it will be located in the tail stock on the left side of the transmission. If your speedo is broken, usually it is the cable that has failed. And, if it has cruise control, the section from the cruise control to the dash would be bad.
If the cruise control will not engage, there might be a problem with the Electronic Fuel Injector or the MAP Sensor. There might also be a problem with the Oxygen Sensor. Some autos have more than one oxygen sensor.
