How to Replace TPMS Sensor Battery?

If you have a car that has a Tire Pressure Monitoring System (TPMS), then you know how important it is to keep the sensors working properly. The sensors help to maintain the correct pressure in your tires, which can improve fuel efficiency and extend the life of your tires. If the battery in one of your TPMS sensors dies, you will need to replace it as soon as possible. In this article, we will show you how to do just that!

1. Locate the Dead Sensor

The first step is to locate the sensor that needs to be replaced. This can be done by looking at the display on your dash. If one of the tire icons is lit up, then that means that particular sensor is not working. You can also use a TPMS tool to scan for sensors that are not functioning properly.

2. Remove the Old Sensor Battery

Once you have located the sensor, you will need to remove the old battery. To do this, you will need a small screwdriver. First, locate the battery cover on the sensor. It is usually black and has a small Phillips head screw in the center. Use the screwdriver to remove the screw and then pry off the cover. Be careful not to damage the sensor as you do this.

Once the cover is off, you will see the battery. It is usually a coin cell battery. Use a small pair of pliers to remove the battery from its holder.

3. Install the New Sensor Battery

Now that you have removed the old battery, it is time to install the new one. Take the new battery and insert it into the sensor. Make sure that the positive side (the side with the + sign) is facing up. Once the new battery is in place, replace the battery cover and screw it back into place.

Congratulations! You have successfully replaced the battery in your TPMS sensor. Be sure to test the sensor to make sure it is working properly before you hit the road. You can do this by starting your car and checking the display on your dash. All of the tire icons should be lit up. If not, then you may need to repeat the steps above. It is also important to note that carrying the right TPMS service tools will make the job easier.
