Can you replace the battery in a Toyota TPMS sensor?
Yes, it is possible to replace the battery in a Toyota Tire Pressure Monitoring System (TPMS) sensor. The TPMS sensor is responsible for monitoring the air pressure in your vehicle's tires and transmitting that information to the dashboard display. While the sensor itself is not designed to be user-replaceable, the battery that powers it can be replaced in most cases.
Understanding Toyota TPMS Sensors
Toyota TPMS sensors are typically located inside the tire, mounted on the wheel rim. They are sealed units that contain a small battery, a pressure sensor, and a radio transmitter. The battery powers the sensor and allows it to continuously monitor the tire pressure and send that data to the vehicle's computer system.
Over time, the battery in the TPMS sensor will eventually die and need to be replaced. This is a common issue that Toyota owners may face, as the sensors are designed to last for several years but not indefinitely.
Replacing the TPMS Sensor Battery
To replace the battery in a Toyota TPMS sensor, you will typically need to follow these steps:
- Locate the TPMS sensor, which is usually accessible from the inside of the tire.
- Remove the sensor from the wheel rim, being careful not to damage the valve stem.
- Identify the type of battery used in the sensor, which is usually a small coin cell battery.
- Purchase a replacement battery that matches the specifications of the original.
- Carefully remove the old battery and replace it with the new one, making sure the polarity is correct.
- Reinstall the TPMS sensor on the wheel rim, ensuring it is properly secured.
- Reset the TPMS system, either through the vehicle's menu or by driving the car for a short distance.
It's important to note that the process for replacing a TPMS sensor battery may vary slightly depending on the specific model of Toyota vehicle and the type of TPMS system used. It's always a good idea to consult your owner's manual or a professional mechanic for specific instructions.
Considerations and Precautions
When replacing the battery in a Toyota TPMS sensor, there are a few important things to keep in mind:
- Be careful not to damage the sensor or the valve stem during the replacement process.
- Make sure to use the correct replacement battery, as using the wrong type can damage the sensor.
- After replacing the battery, be sure to reset the TPMS system to ensure it is functioning properly.
- If you are not comfortable performing the replacement yourself, it's best to have a professional mechanic handle the task.
By following these guidelines, you can successfully replace the battery in your Toyota TPMS sensor and keep your vehicle's tire pressure monitoring system functioning correctly.
Is it worth it to replace TPMS sensors?
You should think twice if you are looking for a cheap replacement TPMS sensor. Usually, replacing all sensors is the ideal option. If your sensor fails, it will affect not only the safety of your vehicle but also its performance. It is better to spend on quality instead of opting to buy cheap.
How long does a TPMS battery last on a Toyota?
7 years
TPMS Life Expectancy
The estimated life expectancy of an OE TPMS sensor is 5 to 12 years, with the average lifespan being 7 years.
How much does it cost to replace 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.
How much does Discount tire charge for TPMS sensors?
$60.00 each
The TPMS sensors cost will depend on the vehicle, however sensor pricing typically starts at $60.00 each and includes the cost of installation. Most of the sensors we offer are also backed with a 6 year/72,000 mile warranty.
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.
Are TPMS sensor batteries replaceable?
The Tire Pressure Monitoring System that alerts you when one of your tires is dangerously low on air usually relies on TPMS sensors in the tires to tell the system the tire pressure is low. Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable.
Can a Toyota TPMS battery be replaced?
Toyota TPMS sensor battery replacement
The battery is covered with potting compound, just like every TPMS sensor, but it's fairly soft and flaky compared to some potting compound. The potting compound is likely the reason most TPMS sensors don't have replaceable batteries.
Can you replace TPMS sensor without removing tire?
You can change a tire while working around a sensor and not removing it. However I recommend doing a 'rebuilt kit' for your sensor. It involves putting on a new rubber grommet, washer and retaining nut. Its good assurance over valves leaking.
How do I know if my Toyota TPMS sensor is bad?
If you notice that your tires have low air pressure and there was no warning from the system, it is most likely due to a failure of a TPMS sensor. Using a tire pressure gauge indicates a problem with the sensor or a tire. Another noticeable side effect is when steering becomes tight.
How much does it cost to replace a tire pressure sensor 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.
