Why does my speedometer keep bouncing between speeds?

Why does my speedometer keep bouncing between speeds?

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. In most cases, only the wiring needs to be changed, or the sensors re-calibrated, to repair the problem.

What should I do if my speedometer is not working?

Troubleshooting speedometer problems mostly call for a replacement of the speed sensor or cable, depending upon the vehicle. Both these repair jobs are simple to perform and can be done at home.

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! A speedometer is an instrument which provides the driver with instantaneous readings of speed.

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.

Why does my speedometer bounce all the time?

My trucks speedometer works smoothly up to 33 mph but then will start bouncing (more aggressively at higher speeds) from random points. I’ve read up and found that it’s often a VSS issue but my trucks cruise control works and will turn on just fine, but causes my speeds to change rapidly with the speedo bounce.

How much does it cost to rebuild a speedometer?

Begin by cleaning and lubricating the cable, but you probably have a combination of issues. On average, a speedometer rebuild runs $150. If you can purchase a guaranteed speedo for less than that by all means do so. Just keep in mind that the old lubricants, even in an NOS unit, dry up over time.
