Can I still drive my car if the speedometer doesn’t work?

By not knowing your speed, you may put yourself at increased risk for citation by police officers. Being unable to determine speed could also increase the potential for an accident. You should stop driving a vehicle with a non-functioning speedometer until it can be checked by a mechanic.
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.
A faulty speed sensor will result in the inability to measure the tire speed which then affects the information given to the engine control unit such that the speedometer does not function, rather, it stays in place at 0 MPH, while the odometer is 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.

What fuse is used for speedometer?
What is a Fuse? Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent. They consist of a low-resistance metal or wire that is used to close a circuit.
What sends signal to the speedometer?
This signal source is generally a speed sender (sometimes called a pulse generator or electonic speedometer pickup) located in the transmission, the vehicle’s PCM (power train control module , ECM, computer) or a GPS sender (which can be mounted in the vehicle or the gauge itself).
How do you tell if a fuse is blown?
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.

What happens if you drive with a blown fuse?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won’t start.
How do you know if your car needs a new fuse?
The blown fuse will be apparent because the wire element within will have melted or burned from the higher electrical current. You can also use a test light or a multimeter to identify the dead fuse without having to pull it out. Both tools are affordable and easy to use.
