Can I replace the batteries in my TPMS sensors?
Yes, you can typically replace the batteries in your vehicle's Tire Pressure Monitoring System (TPMS) sensors. TPMS sensors are designed to have replaceable batteries, allowing you to maintain the system without having to replace the entire sensor unit.
What is a TPMS Sensor?
A TPMS sensor is a small electronic device installed in each of your vehicle's wheels. These sensors monitor the air pressure in your tires and transmit that information to your vehicle's computer system. When the tire pressure drops below a certain threshold, the TPMS warning light on your dashboard will illuminate, alerting you to the issue.
Replacing TPMS Sensor Batteries
Most TPMS sensors use coin cell batteries, such as CR2032 or CR1632, that have a lifespan of 5-7 years on average. When the battery in a TPMS sensor starts to run low, you'll typically see the TPMS warning light come on, indicating that the sensor needs a new battery.
- Locate the TPMS sensor, usually accessible from the inside of the wheel well or behind the tire.
- Use a TPMS sensor tool or a small screwdriver to remove the sensor from the wheel.
- Carefully open the sensor housing and replace the old battery with a new one of the same type.
- Reassemble the sensor and reinstall it in the wheel.
- Reset the TPMS system according to your vehicle's instructions, which may involve driving at a certain speed or using a TPMS reset tool.
It's important to note that some TPMS sensors may be integrated into the tire valve stem, making replacement more complex. In these cases, it's best to have a professional technician handle the battery replacement.
Benefits of Replacing TPMS Sensor Batteries
Replacing the batteries in your TPMS sensors can provide several benefits:
- Maintain Tire Safety: Properly functioning TPMS sensors help ensure your tires are properly inflated, which can improve fuel efficiency, handling, and tire lifespan.
- Avoid Warning Light Issues: A dead TPMS sensor battery can cause the warning light to illuminate, even if your tires are properly inflated.
- Prevent Sensor Replacement: Replacing the battery can extend the life of your TPMS sensors, potentially avoiding the need for more expensive sensor replacements.
By following the proper steps to replace the batteries in your TPMS sensors, you can keep your vehicle's tire pressure monitoring system functioning correctly and maintain the safety and performance of your tires.
Can I drive without TPMS sensors?
If your car has a TPMS sensor but you prefer to drive without one to avoid the inconvenience of a TPMS sensor or warning light malfunctions, then a good alternative for you is to get a TPMS bypass emulator. This is an option for responsible drivers who always check their tire pressure before travelling.
How many years do TPMS sensor batteries last?
5-10 years
TPMS sensors run on batteries that can last anywhere from 5-10 years. Sensor battery life will depend on how much driving you do over time and the conditions that you drive in.
Can I replace my TPMS sensors myself?
In most cases, yes. However, depending on the type of tire pressure sensor system your vehicle has, you may need a special tool to remove and reinstall the sensor. You can purchase a TPMS service kit that includes this tool and replacement sensors at most auto parts stores.
What happens when a TPMS battery dies?
When the battery in a TPMS sensor dies, it will trigger a malfunction warning from the system, indicated by a blinking TPMS light on your dashboard. It may continue to flash, or it may turn solid after 60-90 seconds.
How much does it cost to replace a TPMS battery?
The cost of replacing a TPMS sensor battery varies depending on the make and model of your vehicle, but generally speaking you should expect to pay anywhere from $20-$200 for each replacement battery, plus labor costs if you have it done at an auto repair shop or dealership.
Can I replace the TPMS battery myself?
The potting compound is likely the reason most TPMS sensors don't have replaceable batteries. Potting compound prevents vibration, strain, and shock from damaging electronics. The sensor lives in a wheel that spins fast and rolls over potholes. The potting compound is what keeps it from failing quickly.
How much does it cost to replace all 4 TPMS sensors?
The cost of replacing TPMS sensors can vary greatly depending on several factors, including the type of vehicle, brand, and type of TPMS sensor, location of replacement, and labor cost. On average, replacing a TPMS sensor can range from $50 to $200 per tire, with the average cost being around $100 to $150 per tire.
What happens when TPMS battery dies?
When the battery in a TPMS sensor dies, it will trigger a malfunction warning from the system, indicated by a blinking TPMS light on your dashboard. It may continue to flash, or it may turn solid after 60-90 seconds.
How can I tell which TPMS sensor is bad?
Fill each tire until it reaches its recommended tire pressure. Then, gently release air from each tire and monitor the car display panel. If you release pressure from one tire and it doesn't trigger the system, it might mean that the sensor is defective.
