The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.

Can a blown fuse cause my speedometer to stop working?
Faulty Fuse/Bad Wiring: In very wet conditions, it is possible for exposed wires to get wet and short out, causing a fuse to blow. When the fuse for your speedometer stops working, it can cause the speedometer to drop to zero.
Where is the speedometer sensor located?
Why is my speedometer and odometer not working?
If both your odometer and speedometer are not working, then it’s likely your speed sensor needs to be replaced. These are easily installed and located near the back of your transmission. If only your odometer is busted, then it’s likely the gears that turn the odometer have broken.
How do you fix a speedometer that is not working?
What sensor controls the speedometer?
The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.
Can ABS sensor cause speedometer to stop working?
signs of a failing abs speed sensor it may also turn on the traction and stability control warning lights, if the car has those systems. occasionally, the speedometer may stop working, as well.
Is it expensive to fix speedometer?
Because the cost of repairing a broken speedometer averages around $200, you’ll likely want to replace it with a new one. This can run you about $250, but you’ll have an entirely new unit. The most common cause of a malfunctioning speedometer is a problem with the speed sensor.
How much does a speed sensor cost?
Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45.
How do I reset my speed sensor?
What happens when a speed sensor is faulty?
So, for those asking, “Can a bad speed sensor cause rough idle?” A bad speed sensor will cause rough idle and make a vehicle burn excess fuel than expected. The wrong signals sent from the speed sensor area to the vehicle’s fuel system can also cause other engine issues like reduced acceleration and so on.
Can you drive with a faulty speed sensor?
If the speed sensor has become faulty, it will not immobilise your car, meaning you will still be able to drive it. However, that’s no excuse not to replace a transmission speed sensor as soon as possible.
Does speedometer have fuse?
As such, because odometers and speedometers use the same fuse, the most likely outcome is that your speedometer will also stop working if the odometer stops working due to a blown fuse.
How much does it cost to replace a speedometer cable?
If you’re doing this with a mechanic, they will usually charge you around $100 to $250. Issues with your sensors or your actual speedometer do not cost much but, if the issue lies deeper and requires additional diagnostics, you can expect to pay between $200 and $400.
How do you test a speedometer sensor?
How do you tell if your speedometer is broken?
- Speedometer Does Not Move At All. If the pointer on your speedometer does not budge during acceleration, it’s plausible that the speedometer cable and housing have already failed.
- Speedometer Needle Jumps and Skips.
- Squealing Noises.
How do you troubleshoot a speed sensor?
- 1.) Check Sensor Connection.
- 2.) Check Gap.
- 3.) Resistance Measurement (two wire plug only)
- 4.) Check Power (three wire plug only)
- 5.) Check Wiring (three wire plug only)
How do I know if my speedometer cable is bad?
- Speedometer needle wavers.
- Squealing noises behind dashboard.
- Speedometer needle does not move.
- Check Engine Light comes on.
Does the speedometer affect the transmission?
The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the vehicle speed sensor is faulty, however, at times, the driven gear inside the transmission is at fault.
Can ABS module affect speedometer?
Does ABS sensor affect speedometer? No effect unless you are braking and the speedometer indicates a corresponding reduction in speed. Motorcycles with an ABS system use the ABS wheel speed sensor on the front wheel to calculate and display the road speed of the vehicle.
How do you know if your ABS speed sensor is bad?
- Sign #1: The ABS Light Stays On.
- Sign #2: Traction and/or Stability Control is Disabled.
- Sign #3: It Takes Longer to Stop Your Vehicle.
- Sign #4: Your Vehicle Becomes Unstable During Braking.
- Sign #5: ABS Works Erratically.
How much does it cost to replace an ABS speed sensor?
It will cost between $200 and $400 to replace an individual speed sensor, and there is one for each wheel. Typically, they should be replaced every 30,000 to 50,000 miles.
Is it safe to drive a car without a speedometer?
It is an offence to drive a vehicle that does not have a fully functional speedometer which shows both mph and kmph readings.
What is a speed sensor on a transmission?
The speed sensor detects a gear or target wheel in the transmission and generates an electric digital signal proportional to the speed of rotation. The transmission controls use this information to modify various transmission functions such as shift points and perform diagnostic tests.
How much does it cost to get a speedometer calibrated?
Most speedometer calibrations will cost about $50-100 but some places charge more. You do not necessarily get what you pay for when it comes to calibrations. Calibrations checks should not take a lot of time. The auto body shop will hook your vehicle up to the dynamometer, and measure the accuracy of your speedometer.
