Can you replace the battery in a Toyota TPMS sensor?
As a car owner, understanding the components of your vehicle can save you time and money. One such component is the Tire Pressure Monitoring System (TPMS) sensor, which plays a crucial role in maintaining tire safety and performance. In this article, we will explore whether you can replace the battery in a Toyota TPMS sensor and the steps involved in the process.
Understanding TPMS Sensors
TPMS sensors are designed to monitor the air pressure in your tires and alert you when the pressure falls below a certain threshold. In Toyota vehicles, these sensors are typically mounted inside the tire, attached to the valve stem. Over time, the battery within the TPMS sensor can deplete, leading to malfunctioning sensors and warning lights on your dashboard.
Can You Replace the Battery?
In most cases, the battery in a Toyota TPMS sensor is not designed to be replaced. The sensors are usually sealed units, meaning that when the battery dies, the entire sensor must be replaced. This is a common practice across many vehicle manufacturers, including Toyota.
Steps to Replace a TPMS Sensor
If you find that your TPMS sensor is malfunctioning due to a dead battery, here are the steps you should follow to replace it:
- 1. Gather Necessary Tools: You will need a tire jack, lug wrench, and a new TPMS sensor compatible with your Toyota model.
- 2. Lift the Vehicle: Use the tire jack to lift the vehicle and remove the wheel where the faulty TPMS sensor is located.
- 3. Remove the Old Sensor: Unscrew the valve stem nut and carefully detach the old TPMS sensor from the wheel.
- 4. Install the New Sensor: Attach the new TPMS sensor to the valve stem and secure it with the nut.
- 5. Reinstall the Wheel: Place the wheel back onto the vehicle and tighten the lug nuts securely.
- 6. Reset the TPMS System: After replacing the sensor, you may need to reset the TPMS system using a diagnostic tool or by following the vehicle's manual instructions.
Conclusion
While you cannot replace the battery in a Toyota TPMS sensor, replacing the entire sensor is a straightforward process that can be done with basic tools. If you're unsure about performing this task yourself, it's always a good idea to consult with a professional mechanic to ensure your vehicle remains safe and roadworthy.
Frequently Asked Questions
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 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.
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.
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 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.
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 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.
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.
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.
