The TPMS sensor battery is one of the most important parts of your car. It monitors the air pressure in your tires and sends that information to your dashboard display. If the TPMS sensor battery dies, you will not be able to get accurate information about your tire pressure. In this article, we will discuss how to know when the TPMS sensor battery is dead.
What is the TPMS Sensor Battery?
The TPMS sensor battery is a small, round, silver button cell battery that is located in the center of your car’s dashboard. It sends information about your tire pressure to your car’s computer system. If the battery dies, you will no longer be able to get accurate information about your tire pressure. Thus, it is important to know when the TPMS sensor battery is dead.
How to Know if the TPMS Sensor Battery is Dead
There are a few signs that will indicate that your TPMS sensor battery is dead. Here are some of the most common signs:
1. Your Tire Pressure Light is On
If your tire pressure light is on, it means that the TPMS sensor battery is dead. The tire pressure light is located on your dashboard. It looks like an exclamation point inside of a circle. If you see this light, it means that your car’s computer system is not receiving information from the TPMS sensor. Several things can cause this, but the most common cause is a dead TPMS sensor battery.
2. Your Tire Pressure Display is Blank
If your TPMS system is working properly, you’ll see the tire pressure readings of all four tires on your dash display. If one or more of the tire readings is missing, it could be a sign that the sensor battery is dead. To check if this is the case, look at the display when the car is first turned on. If the reading is there initially and then goes blank, it’s likely that a sensor battery is dead.
Another way to tell if a sensor battery is dead is by the position of the tire on display. If the display shows the tire in the correct position, but the pressure reading is missing, it’s a good indication that the sensor battery is dead.
3. The Tire Pressure Reading is Incorrect
If you know your tire pressure is correct, but the reading on display says otherwise, it could signify that the sensor battery is dead. Inaccurate readings can also be caused by environmental factors such as extreme cold or heat, so if the reading is far off from the actual pressure, it’s best to check the sensor battery.
To test if the sensor is working properly, use a tire pressure gauge to measure the tire’s pressure. If the reading on the gauge is different from what’s displayed on your dash, the TPMS sensor battery is likely dead. You must also make sure that your TPMS repair kit is with you so that you can easily fix the problem.
With the help of this guidance, you will now be able to tell when the TPMS sensor battery is dead. Keep in mind that it is important to have a working TPMS sensor battery to get accurate information about your tire pressure and to avoid any potential problems.
