A TPMS sensor is a device that measures tire pressure. It is usually mounted on the wheel, transmits data to a receiver, and then displays the information on a dash-mounted readout. In this article, you learn about how to test the TPMS sensor battery.
The battery in a TPMS sensor needs to be tested because it powers the sensor and helps it transmit data accurately. A dead or dying battery can cause the TPMS sensor to stop working properly, leading to inaccurate tire pressure readings.
Let’s get started with detail about how to test the TPMS sensor before installing it and the preventions before testing the TPMS sensor battery.
How To Test TPMS Sensor Battery
It is important to know how to test the TPMS sensor battery. It can last 5 to 10 years, but if it starts to fail, you’ll need to replace it. Here’s how to test your TPMS sensor battery:
Step 1: Remove The Sensor From The Tire
The first step is to remove the sensor from the tire. Use a flat-head screwdriver to unscrew the sensor from the valve stem at the tire’s end. Then remove the sensor’s battery cover, which is usually a small plastic cap on the back.
Step 2: Use A Multimeter To Test The Voltage Of The Battery
A multimeter is an important tool for testing the health of your TPMS sensor battery. To test the voltage of your battery, follow these steps:
- Set your multimeter to the DC voltage setting.
- Touch the multimeter’s positive lead to the battery’s positive terminal.
- Touch the negative lead of the multimeter to the negative terminal of the battery.
- Check the reading on the multimeter. If it reads 12 volts or higher, your battery is in good shape. If it reads below 12 volts, your battery may need replacement.
Step 3: Interpret The Results Of The Test
After checking the sensor and ensuring there is no blockage, the next step is to interpret the test results. If the light on the dash does not come on or blinks rapidly, it indicates a problem with the sensor. If the light is on steady, the sensor is functioning properly.
If the light on the dash is off, this could mean a few things. First, check to see if the fuse for the TPMS system has blown. If it has, replaces it and then test the system again. If the fuse is not blown, then there may be a problem with the TPMS module itself.
Step 4: If The Battery Needs To Be Replaced, Do So
If the battery needs to be replaced, follow the manufacturer’s instructions. Make sure to follow all safety procedures when working with batteries.
When replacing the battery, it is important to clean the contact points and apply a thin layer of grease before reconnecting the sensor to the vehicle. It will help ensure the connection is good and will help prevent corrosion.
Once the new battery is in place, test the sensor to see if it is functioning properly. If not, another issue with the sensor may need to be addressed.
This way, you get the answer of how to test the TPMS sensor and troubleshoot the TPMS light on the dashboard.
Preventions Before Testing TPMS Sensor Battery
As the weather gets colder, it’s important to ensure your car is prepared for changing conditions. One thing you should check is the battery in your TPMS sensor. These sensors tell you when your tire pressure is low, so it’s important to have them working properly. Here are a few tips before the test the battery in your TPMS sensor:
- Ensure the sensor is properly mounted on the wheel and the tire pressure is at the correct level.
- Check the condition of the battery and clean any corrosion from the terminals.
- Test the battery’s voltage to see if it needs to be replaced.
By following these simple steps, you can ensure that your TPMS sensor is working properly and that you won’t have any trouble down the road.
What Happens When The TPMS Battery Dies
When the TPMS sensor battery dies, the sensor will no longer be able to transmit a signal to the TPMS control unit. It can cause the TPMS system to malfunction and may trigger a warning light on the dash. If the battery is not replaced, the TPMS system will not be able to monitor tire pressure levels properly, which could lead to unsafe driving conditions.
How Do TPMS Sensors Get Power?
For most of us, our car is one of the most important pieces of equipment we own. It gets us to and from work, helps us run errands, and sometimes even serves as our office away from home. So, it can be a major inconvenience when something goes wrong with our car.
One problem that can occur is a dead TPMS sensor battery. TPMS sensors are located in each tire and monitor the air pressure. If the pressure gets too low, the sensor sends a signal to the car’s computer, which then alerts the driver. TPMS sensors get power from batteries, which will eventually die and need to be replaced.
How Long Do TPMS Sensor Batteries Last
Batteries in TPMS sensors can last anywhere from five to ten years. However, battery life will vary depending on the make and model of the sensor, as well as the driving habits of the vehicle owner.
For example, if a TPMS sensor is regularly exposed to high temperatures or frequently goes through potholes, its battery life will be shorter.
To test the battery in a TPMS sensor, use a multimeter to check the sensor’s voltage output. The ideal voltage range for most TPMS sensors is between 2.5 and 3.6 volts. If the voltage output is lower than this range, it’s time to replace the battery in the TPMS sensor.
Do TPMS Sensors Have Batteries
When it comes to your car’s tire pressure monitoring system (TPMS), you may be wondering if the sensors have batteries. The short answer is: yes, they do! Here’s a quick look at how TPMS sensors work and how to test the battery life on yours.

Your car’s TPMS is made up of sensors that are mounted inside each tire. These sensors constantly monitor the air pressure in your tires and send a signal to your car’s computer when the pressure gets too low.
To test the battery life on your TPMS sensor, you’ll need a special tool that can be purchased at most auto parts stores. With this tool, you can check the voltage output of each sensor. If the voltage is below 2.0 volts, then it’s time to replace the sensor battery.
Benefits Of TPMS Sensor Battery
As the seasons change, it’s important to ensure your car runs smoothly. One way to do this is by testing your TPMS sensor battery. It may seem like a daunting task, but it’s actually quite simple.
There are many benefits to having a TPMS sensor battery.
- It can help you save money on gas. With the rising cost of gas, any little bit helps.
- It can help extend the life of your tires. By keeping an eye on your tire pressure, you can avoid flat tires and other problems down the road.
- It can help reduce the risk of accidents. If your tires are overinflated or underinflated, you can be more likely to get into an accident.
So don’t wait until there’s a problem with your car before you test your TPMS sensor battery. A little preventative maintenance now can save you time and money later on.
What Causes The TPMS Low Battery?
The main cause of a TPMS low battery warning is a weak or dead battery in one of the sensors. The battery may be weak due to age, corrosion, or simply because it was not designed for long-term use. In some cases, the sensor may be damaged and need to be replaced.
Another cause is the load and configuration of the sensors connected to the vehicle. If a sensor is defective and has an incorrect load or configuration, it can cause the system to shut down.
Conclusion – How To Test TPMS Sensor Battery
On various types of vehicles, tire pressure monitoring systems (TPMS) monitor the air pressure inside pneumatic tires. TPMS sensors are mounted onto each tire and wheel assembly and wirelessly transmit data regarding the tire’s air pressure to a central receiver in the vehicle.
It is important to regularly test your TPMS sensor battery because if one of your tires loses air pressure, you want to be sure that your TPMS sensor will be able to send a signal to your vehicle’s computer so that you can be alerted.
I hope you enjoyed this article on how to test the TPMS sensor battery and found it helpful.
