The speedometer cable may be damaged or broken. If the vehicle has cruise control, the cruise control transducer could be faulty and a new one should put in its place. Scenario: you are driving and suddenly the speedometer needle becomes stuck. Even when you slow down or speed up, the needle stays in the same place.
What causes a speedometer to stick?
Older analog speedometers often stick due to problems with their speedometer cable or wear and tear damage to the speedometer itself. Digital speedometers and gauges in newer cars that “stick” or remain at a specific speed likely necessitate replacement by a dealership.
What causes my speedometer needle to bounce?
“Bounce” in this context means that although the car is moving at a constant speed, the speedometer’s needle seems to jump around at +/- 5 MPH or so of the current speed, never resting at any particular value. Common causes for this problem are a binding speedometer cable, a failing angle drive, or a slipping dust cap.
Why does my speedometer bounce?
Bouncing or jerking of speedometer. In cases where the speedometer does not settle on any particular reading but keeps moving between speeds, it is almost always due to bad wiring, in case of a cable system, or a faulty speed sensor.
What’s the difference between a speedometer and speed sensor?
A speedometer is an instrument which provides the driver with instantaneous readings of speed. Traditional speedometers used gears and wires to determine speed, while most modern vehicles use speed sensors for the same.
Where was the speedometer before the speed gun?
Before the invention of the speed gun, cars in the early 20th century were required to have two speedometers, one on the dashboard and one on the front fender, so that police could see how fast they were going!

How accurate is the speedometer?
No speedometer can be 100 percent accurate. In fact, most manufacturers build speedometers so they fall within a fairly narrow tolerance range, no more than 1 percent to 5 percent too slow or too fast. As long as a car is maintained at factory specs, its speedometer should continue to register vehicle speed within this range.

What happens if there is no speed signal?
Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
What happens if the speed sensor does not work?
If this speed sensor fails, your speedometer may not work. Some odometers use the same sensor as the speedometer, and may cease to function as well. Without a speed sensor, the transmission control unit (TCU) may have a hard time knowing when or how quickly to shift gears.
What to do if your speedometer doesn’t work?
