The Tire Pressure Monitoring System, which notifies you when a tire is dangerously low on air, typically uses TPMS sensors embedded in the tires to detect low tire pressure. The majority of TPMS sensors use internal batteries that cannot be changed to power them.
The lithium ion batteries in a TPMS sensor have a lifespan of 5 to 10 years. The duration of the TPMS sensor batteries is difficult to predict because it depends on how many radio frequency broadcasts the sensors send out. The amount of driving you perform over time and the conditions you drive in will affect the sensor battery life. The TPMS battery life is less affected by cold conditions than by warmer ones. When compared to continuous pace, stop-and-go traffic has a greater effect on TPMS battery life. This is due to the fact that sensors send out more radio frequency broadcasts as a vehicle changes its speed.
The system will issue a malfunction warning when a TPMS sensor’s battery runs out, which will be visible as a blinking TPMS light on your dashboard. After 60 to 90 seconds, the light may either continue to flash or turn solid. Be a repair appointment as soon as you can if you receive this warning, but also check the tire pressure in each tire right away to make sure you have safe inflation all around.
You can change each individual TPMS sensor separately if one of them malfunctions and needs to be replaced. The other sensors, on the other hand, are probably on the verge of failing as well if the failure was brought on by a dead sensor battery. You might wish to proactively replace all the sensors so you have brand-new sensor batteries all around when you take into account the time and hassle of taking your car off for a sensor replacement.

Toyota tire pressure sensors: how long do they last?
The TPS batteries last between three and five years, according to our experience here at the Lake Charles Toyota Service Center. If any of your sensors malfunction within the first three years, the manufacturer’s guarantee can still apply, according to service manager Kenny Guillory.
How much does a Toyota TPMS sensor replacement cost?
Tire pressure sensor replacement for a Toyota Corolla typically costs $99, which includes $4 for components and $95 for labor. Prices may change based on where you are.
Where do I get TPMS service?
Certified technicians should inspect and maintain the TPMS system. Modern cars come equipped with tire pressure monitoring systems as standard equipment, thus reputable tire shops employ technicians who have received specialized training in TPMS evaluation and repair. If you require TPMS service, contact your neighborhood Tirebuyer installer.
How often do TPMS sensors need to be replaced?
TPMS sensors are made to last for a long time. A lifespan of 510 years is likely. Given their price, most drivers will opt to replace TPMS sensors “as needed,” or only when their batteries run out of power or other TPMS components malfunction. (The onboard computer in your car ought to react and issue a warning of a TPMS issue or failure.)
Typical TPMS issues that necessitate sensor replacement include:
- TPMS sensor battery failure
- broken TPMS sensors
- Gaskets and/or seals for the TPMS sensor are worn out.
- The TPMS sensor doesn’t send a signal (many possible causes)
- The TPMS valve cores or caps seize up.
Replacing TPMS sensors
For replacement sensors, we advise going to a Tirebuyer installation or a car dealership. To avoid complications, make sure you are purchasing exact OE replacement sensors or an equivalent aftermarket part, regardless of the supplier.
Be aware that some vehicles might need to have new TPMS sensors programmed by the dealership in order for them to work along with the vehicle. Others can be encouraged to accept the new sensors using an onboard command, such as a simple “reset TPMS button on the dashboard, or within the onboard computer. Some vehicles adapt to the new sensors automatically after some time of driving. To learn the method for your car, consult the owner’s manual or speak with your service shop.
Do you need new TPMS sensors when replacing tires?
Not necessary, I say. It is absolutely good to leave the same set of TPMS sensors placed with the wheels when fitting a new set of tires because they can outlast a set of tires, sometimes even many sets.
The TPMS sensors should be examined while the tires are being serviced. Ask the technician to inspect the TPMS sensors and system when you are getting new tires put.
Rebuilding TPMS sensors
It takes specialized equipment and knowledge to maintain a vehicle’s TPMS. The valve stem where the air is injected typically has a TPMS sensor attached to it on each wheel. A rubber grommet that seals the air in the tire and shields the sensor from the elements is located between this stem and the wheel.
The rubber grommet needs to be changed, along with the nut that holds the stem and the nickel-plated valve core in the stem, just like the rubber valve stem that was replaced at every tire change for years since the weather and other conditions caused wear.
The internal parts of the caps are protected by moisture seals because moisture and corrosion eat away at the stem. All of these parts should be changed when replacing the tires to prevent the development of a leak (or in tire lingo, the TPMS sensor needs to be rebuilt). For providing this service, your installer will often charge a little additional price.
There may also be a tiny additional cost while rotating tires, depending on the generation and kind of TPMS, as some cars need to “relearn the position of each sensor once the tires have been relocated.” To ensure that the system is functioning effectively, the technician needs specialized knowledge, tools, and time. Each vehicle make and model has its own distinct relearning technique.
The final word on TPMS
The performance and safety of your vehicle’s tires are largely dependent on its tires, and the performance of tires depends on maintaining adequate tire pressure.
In terms of safety and long-term savings, TPMS offers enticing advantages. The advantages of TPMS, in our opinion, clearly outweigh the disadvantages. Maintaining the TPMS system in excellent working order is essential if your car has one. If your car lacks an original equipment TPMS system, an aftermarket system is unquestionably something to think about.
What is the price of replacing all TPMS sensors?
Replacement of a TPMS sensor typically costs between $203 and $245. While parts are priced between $149 and $177, labor costs are predicted to be between $54 and $68. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account. There might be more repairs required.
Can I change the TPMS sensors on my own?
Older Corvettes and Cadillacs with run-flat tires have had tire pressure monitor systems since the 1990s, and since the model year 2008, they are required on all passenger cars and light trucks.
Unless a sensor malfunctions and needs to be replaced, TPMS systems require little to no maintenance. The typical lifespan of the tiny lithium ion button batteries found inside TPMS sensors is 5 to 10 years, with an average lifespan of 7 years for many. Driven miles affect battery life. The more signals a vehicle’s TPMS sensors transmit while it is being driven, the more miles it travels each year. In order to preserve battery life, the sensor only produces a signal at predetermined intervals (30 to 60 seconds or longer). As a result, sensors in vehicles with high annual mileage typically malfunction before those in vehicles with low annual mileage.
Additionally, TPMS sensors may stop working at any time due to corrosion or physical harm. Some original equipment TPMS sensors on Asian-made vehicles have a serious issue with aluminum stem corrosion. The valve stem may abruptly fall off after a few years of exposure to road salt deterioration.
A TPMS sensor battery has a service life that is typically equivalent to the wear life of the tires that came with the vehicle. A good pair of tires should last between 60,000 and 80,000 miles, thus even if the original sensors are still in good condition, the car will require new TPMS sensors by the time it needs new tires.
Since the sensors are likely to fail before the next tire replacement, they should be replaced whenever a new pair of tires is mounted. They could continue for another year or two, or they could stop. They probably won’t last for another 5 to 7 years, though.
If a TPMS sensor is harmed during tire removal or rim mounting, it might also need to be replaced. If a clamp-on style sensor with a hex nut and grommets at the base is temporarily removed from a wheel for tire maintenance or put in a different rim, a replacement nut and grommets must be used to minimize the danger of air leakage. For this purpose, service kits that include fresh grommets, hex nuts, valve cores, and caps are offered.
With a plethora of various sensor designs and types, vehicle manufacturers did their best to make the aftermarket’s job extremely difficult when TPMS was first introduced. Aftermarket vendors have solved this problem in recent years with a variety of “universal sensors that work in a wide range of applications. This significantly lowers the number of SKUs required to serve the market and makes replacement for installers simpler.
Many TPMS systems require programming with a special TPMS tool once sensors have been replaced so the TPMS control module will know which wheel sensor is which, even though some TPMS systems can self-learn the position of the individual wheel sensors. On vehicles that actually show individual tire pressure readings on the instrument panel, this is crucial. Sensor locations typically don’t matter on vehicles that merely provide a generic low tire pressure alert (no specific tire pressure readings or placements). By using a pressure gauge to check each tire, the driver must determine which tire is low.
Rubber-stemmed, snap-in TPMS sensors are just as simple to change as regular valve stems. No unique equipment is required. Hex nut stems must, however, be meticulously tightened to a precise value using a TPMS valve stem tool or an exact inch-pound torque wrench.
How can I tell which TPMS sensor is malfunctioning?
Reading the trouble codes with an OBD2 Scanner is the simplest approach to determine which TPMS sensor is defective.
You can also check there to see if any pressure is unnecessary if your automobile has a dashboard display showing the tire pressure for each wheel.
The majority of cars require a diagnostic scan tool that can read both the TPMS system and the ECU from your car. You may either visit a mechanic shop to get it done for you or check out our post on the Best OBD2 Scanners to locate a scanner to do it.
If you purchase new tires, should you replace the TPMS?
When a TPMS sensor’s battery dies, it is routinely changed. The lifespan of a TPMS sensor is typically equal to its battery life because very few sensors have detachable batteries.
Do I need to replace TPMS when replacing tires?
Although you don’t have to replace your TPMS sensors when you get new tires, doing so if the sensors are more than a few years old is frequently convenient. Older sensors might not live as long as your new tires because the majority of TPMS sensor batteries only last five to 10 years. The trouble of upgrading TPMS sensors in the middle of the tire lifecycle is something that many drivers would rather avoid.
A TPMS Service Kit is advised by Midas while changing tires. To guarantee a proper fit with your new tires, this package includes replacement components for the valve stem seals and nuts on the sensor.
Based on the expected lifespan of your new tires, your neighborhood Midas specialist may assist you in determining whether to update your TPMS sensors. When that time comes, we’ll be there to repair your sensors.
