If your speedometer isn’t working properly, it can be a problem if you need to drive home in the middle of the city. Luckily, there are some simple steps that you can take to fix this problem yourself and get your speedometer working again.

Symptoms

If your Nissan Sentra speedometer is not working properly, you may experience problems with the gas gauge, odometer, or tachometer.

The electrical connections to these devices may be loose or corroded. This could cause the speedometer to not work properly.

Causes

Your speedometer is a very important part of your car and it will give you an accurate reading of how fast you are going. If your speedometer is not working properly, then you cannot get accurate readings of how fast you are going. You can check the most common problems below.

Faulty Speed Sensor – The speed sensor is in the engine bay of your car and it uses a magnet to determine how fast your car is going. If this magnet becomes damaged, then it cannot tell the car’s computer what speed it should run at. To fix this, you will need to replace the speed sensor with a new one.

Wiring Problem – If you have a problem with your car’s wiring, you will not be able to turn on any of your car’s electronic systems or even turn on the lights in your car. It is very common with older vehicles and is caused by many different things like a short circuit in the wiring or a faulty fuse.

For this to be fixed, you will need to take apart your entire car and examine all of the electrical wirings to see if there are any problems or damage that have occurred over time. You may want to consult with a mechanic to see what is wrong with your car.

Procedures

Here are some simple steps that you can take to fix the speedometer on your Nissan Sentra:

Open the hood of your car and locate the speedometer in the center of the dashboard. You will see two cables attached to it that have an arrow printed on them.

Use a flathead screwdriver to pry them off with your fingers and take out any debris or dirt that may be inside of them.

Unplug both cables from the speedometer, then plug them back in one at a time and test each one by placing it on a dashboard surface or a flat surface in front of you, then see if it works.

You should now be able to turn on your speedometer and use it as normal. If you are still having problems with your speedometer, then you may want to consider taking it to a mechanic for further inspection.
