How does a speedometer cable work?

The cable is a bit like a mini driveshaft: if one end of the cable rotates, so does the other—even though the cable is long and bendy. At the top end, the cable feeds into the back of the speedometer. When it rotates, it turns a magnet inside the speedometer case at the same speed.

How do I choose the best speedometer for my car?

You can consult the parts department at a certified dealer to ensure that you order a speedometer that will fit properly into your instrument panel. The gauge won’t just need to meet dimension specifications, but you also have to consider what all connects to your specific vehicle’s speedometer.

Are speedometers Universal?

The dimensions of a speedometer vary from vehicle to vehicle and after-market products are most certainly not universal. You can consult the parts department at a certified dealer to ensure that you order a speedometer that will fit properly into your instrument panel.

Why is my speedometer not working after an odometer repair?

The answer depends on the make and year model of the vehicle; however, the most likely cause of the speedometer/odometer not working subsequent to some unrelated repairs would be the inadvertent disconnecting of the speed sensor during the repair work. Thanks!

How does a speedometer work?

How speedometers work—a closer look. When the engine turns over, the driveshaft turns to make the wheels spin round. The speedometer cable, powered by the driveshaft, turns as well. The cable spins a magnet around at the same speed inside the speed cup. The magnet rotates continually in the same direction (in this case, counter-clockwise).

How does the Speedo cable work?

Linked to this gear wheel, and driven by it, is a small pinion gear , the speedometer chive pinion, which links in turn to the speedometer cable that runs up to the speedometer itself. The speedo cable consists of an inner cable running inside a protective outer sheath.

Where does the speedometer cable go on a car?

The speedometer cable is driven from the gearbox, and curves smoothly up through the engine compartment and the bulkhead to connect with the back of the speedometer. Speedometer failure is likely to be caused by a fault in the cable that runs from the gearbox to the back of the speedometer gauge.

How does the speedometer work on a Volkswagen Beetle?

The early Volkswagen Beetle and many motorcycles, however, use a cable driven from a front wheel. When the vehicle is in motion, a speedometer gear assembly turns a speedometer cable, which then turns the speedometer mechanism itself.

Why does my speedometer stop working?

The speedometers in modern vehicles use speed sensors to calculate the speed while the older models make use of gears and wires for the same purpose. The speedometer stops functioning when the sensors don’t work, dials malfunction, or the wiring becomes bad.

How much does it cost to replace a speedometer on average?

The most common issues related to speedometers not working in a vehicle can be traced back to the failure of speed sensors. Most shops ask between $100 to $250 for speed sensor replacement (in-house). However, the costs are significantly lesser for DIY repairs, as the driver will be absorbing only the price of the sensor itself.

Why is my odometer not working on my Honda Civic?

How does the speedometer work in a car?

The speedometer determines the vehicle’s speed by drawing information from the transmission and driveshaft. The ECU (engine control unit) converts the driveshaft’s rotation speed to the vehicle’s linear speed and then passes the information to the speedometer.
