Speedometer Not Working? Here’s What Might Be Wrong
If you’re experiencing this issue, it could be caused by several factors, such as a faulty sensor, electrical glitches, or issues with an electronic speedometer.
Common Causes of the Speedometer Not Working
Before we go to fixing this issue, let’s learn what causes the problem that leads to your vehicle’s speedometer not working.
- Faulty Speed Sensor: The role of this sensor is to transmit data to the speedometer. If your car’s sensor malfunctions, it may cause the speedometer to stop working or give out inaccurate speed readings.
- Electrical or Technical Issues: A broken fuse or a loosened or damaged cable can result in the speedometer not functioning properly. This is why it is essential to check the fusebox, cable, and wires in the system to be assessed properly if you face this issue.
- Malfunctioning Electronic Speedometer: In modern vehicles, a glitch or failure in the systems can result in this problem, too. So you need to make sure that the software of your car is well-configured and updated regularly.
How to Fix a Speedometer
If you ever run into this issue, don’t worry. Just follow this simple step-by-step guide—it’ll help you figure out what’s going on and maybe even fix it yourself.
Step 1: Run a Diagnostic Scan
If your car’s speedometer isn’t working, you can use a tool called an OBD2 scanner. Plug it into the port under your steering wheel. It will display error codes related to your car’s system. If you’re unsure what the codes mean, refer to the scanner’s manual or look them up online.
This scan is essential as it assists in indicating the exact problem. It will tell you whether it is the sensor or the wires, just through a quick scan.
Step 2: Check the Fuse
If the OBD2 scanner identifies that your system has a blown fuse, then this problem is relatively easier to fix. What you can simply do is try to look for the fuse box in your vehicle. Don’t panic if you are unable to locate it; just use your vehicle’s panel or ask a friend who has a better understanding of cars. From there, the work gets simpler, you can replace the fuse and get your speedometer to work.
If it happens again, that means the problem runs deeper.
Step 3: Inspect the Wiring
Next, check for any loose or damaged wires. This could be why your speedometer isn’t working, because power may not be reaching the system. Inspect the front of your car and inside the dashboard for any worn-out wires or disconnected plugs.
When you find any, please be careful when fixing them. Take all the safety precautions and involve someone who knows it. Otherwise, this is a good time you visit a professional who can help to solve the issue.
Step 4: Replace the Speed Sensor
The sensor is the last part that you have to go through. It plays a huge role by sending data to the speedometer, which helps it to function properly.
Step 5: Repair the Speedometer
If you’ve ruled out sensors, wiring, and fuses, the issue might be with your speedometer dial itself. You can take the car to a professional, who might repair the part of the speedometer or suggest that you replace it altogether. You must understand the issue and then decide accordingly.
When to Seek Professional Help
If you enjoy working on cars, it makes sense to try fixing the problem yourself. Basic checks and simple repairs can be satisfying to handle on your own.
