How often should TPMS sensors be replaced?

Direct TPMS sensors typically last about five to seven years due to their built-in battery life, though some may stretch to a decade with favorable conditions. Many drivers replace sensors when tires are changed or if a sensor fails. Indirect TPMS does not use a battery-powered sensor and relies on wheel-speed data, so it does not have the same replacement cycle.

Understanding the replacement timing requires considering the system type, battery health, tire maintenance practices, and climate. This guide breaks down the basics, common timelines, and practical steps to manage TPMS maintenance.

Direct vs Indirect TPMS and replacement implications

Here is a quick distinction and the basic replacement implications for each type.

• Direct TPMS sensors: mounted in the wheel and powered by a battery; their life is finite and battery failure is a common reason for replacement.


• Indirect TPMS: uses ABS wheel-speed data to infer low tire pressure; no physical sensor battery to replace, but the system may still need relearning after tire changes or wheel service.


• Tire service interactions: during tire changes, direct sensors may be reused or replaced depending on age, condition, and shop policy; indirect systems rely on software recalibration rather than new hardware.

Bottom line: Direct sensors have a finite life tied to the battery, while indirect systems rely on software logic and do not require sensor replacements on a fixed schedule.

Factors that influence replacement timing

The following factors can shorten or extend sensor life and influence when you should replace TPMS components.

• Battery degradation in direct sensors: typical lifespan ranges from about 5 to 10 years, with performance gradually diminishing over time.


• Environmental exposure: road salt, moisture, and harsh climates can accelerate corrosion and failure in direct sensors and valve stems.


• Driving patterns and mileage: heavy mileage and frequent tire rotations can impact sensor longevity.


• Tire service handling: improper mounting, puncture repairs, or damage during tire service can harm sensors or valve stems.


• Vehicle make and OEM recommendations: some manufacturers have specific guidelines on replacement intervals or relearn procedures after service.

In practice, sensor life is variable. Battery health and the conditions listed above largely determine when a replacement becomes necessary.

Recommended timelines and practical steps

These baselines reflect common industry practice, but you should confirm with your tire shop or dealer for your specific vehicle.

• Direct TPMS sensors: replacement is often considered around 5–7 years, especially if the battery shows signs of weakness or if tires are due for replacement. Many shops recommend replacing sensors during major tire changes or if the sensor has failed.


• Direct TPMS sensors during tire replacement: some facilities replace all sensors if they are older or if there is a risk of uneven readings; others may reuse if inspection shows the sensors are in good condition.


• Indirect TPMS: no physical sensor replacement is required; perform a system relearn/reprogram as part of tire service if needed.


• Relearn procedure: most systems require a relearn after sensor replacement or tire rotation; the exact method varies by vehicle and may require a dealer or tire shop to perform the procedure.

In short, plan sensor replacement around the five-to-seven-year window for direct sensors, especially when tires are being replaced, and be mindful of potential corrosion or damage that can necessitate earlier action.

Signs that TPMS sensors may need replacement

Look for these indicators that suggest a sensor or the TPMS system may be failing and requires inspection.

• TPMS warning light remains on after tire inflation adjustments or inflates inconsistently across wheels.


• Inability to relearn sensors after tire service or rotation.


• Visible damage to valve stems or rims, or corrosion around the sensor hardware.


• Frequent false readings or sudden, unexplained changes in tire pressures.

If you notice these signs, seek a professional inspection to determine whether sensor replacement, relearning, or system diagnostics are needed.

Summary

Direct TPMS sensors generally require replacement on a five- to seven-year timeline, driven mainly by battery life, while indirect TPMS does not rely on battery-powered sensors and focuses on software calibration. Replacement decisions are commonly tied to tire changes, sensor condition, and the need for relearn procedures. For most drivers, aligning sensor replacement with tire service and monitoring battery health offers a practical path to maintaining accurate tire pressure readings and system reliability.

What is the life expectancy of a TPMS sensor?

TPMS sensors have a lifespan of 5 to 10 years, or approximately 90,000 to 120,000 miles, as their batteries are non-replaceable. When the battery dies, the entire sensor unit must be replaced. Driving habits, such as constant stop-and-go traffic, and environmental factors like road salt can affect their longevity. It is often recommended to replace all sensors at once to avoid future tire mounting fees.
 
Factors affecting lifespan

• Battery life: The internal battery is the most common reason for replacement. 
• Damage: Sensors can be damaged by potholes, curbs, accidents, or from a flat tire. 
• Environmental conditions: Exposure to road salt can cause corrosion. 
• Driving habits: Frequent stop-and-go driving can reduce battery life, while cold temperatures can also impact performance, notes REDI-Sensor and Tadiran Batteries GmbH. 

What to do when a sensor fails

• Replace all sensors: It is cost-effective to replace all four sensors at the same time, as the others are likely nearing the end of their life as well. 
• Recognize the warning signs: A blinking TPMS warning light indicates a system malfunction, say DensoProducts.com and TPMS Direct. The light will typically blink for 60-90 seconds before turning solid. 

Do I need to replace all 4 TPMS sensors?

You do not have to replace all four TPMS sensors, but it is highly recommended, especially if the failure is due to a dead battery. The other sensors are the same age and will likely fail soon, so replacing them all at once is more efficient and can save you money and time on future appointments. 
Reasons to replace all four

• Batteries are short-lived: TPMS sensor batteries typically last 5 to 10 years and are not user-replaceable. If one has failed, the others are likely close to failing as well. 
• Cost-efficiency: It is more efficient to replace all four at once. You will save money on labor costs by having the tire removed only once for all sensors, rather than paying for labor four separate times. 
• Convenience: It prevents multiple future appointments, as each sensor will need to be replaced as its battery dies. 
• Timing: If you are replacing your tires anyway, now is the perfect time to replace the TPMS sensors, as the tire is already off the wheel. 

When you might replace only one

• If the sensor failed for a different reason: If a sensor fails due to physical damage (like hitting a curb) instead of a dead battery, the other sensors might still be good. 
• If you are on a tight budget: You can technically replace just the one that failed and wait to replace the others as they fail, but this is not the most efficient long-term solution.

Is it worth replacing TPMS sensors?

Yes, replacing tire pressure sensors is worthwhile for safety and efficiency, especially if they are 5–10 years old, have dead batteries, or are damaged. However, some drivers replace them only when a sensor fails, while others, especially those with seasonal tires, choose to bypass replacement to save on costs, though this may lead to the warning light remaining on. 
Reasons to replace tire pressure sensors

• Safety: Proper tire pressure is crucial for safe handling and to prevent blowouts. 
• Fuel efficiency: Underinflated tires can negatively impact your gas mileage. 
• Tire wear: Maintaining correct pressure extends the life of your tires. 
• Sensor lifespan: TPMS sensors have a lifespan of about 5 to 10 years, after which the internal battery may die or other components can fail. 
• Damage: Sensors can be damaged by corrosion or during tire changes. 

When to replace

• Warning light: If the TPMS warning light stays on even after you've inflated your tires to the correct pressure. 
• Inaccurate readings: If you're getting inconsistent or incorrect pressure readings. 
• Age: When the sensors are 5 years or older, as the battery life is likely ending. 
• During tire service: It's a good idea to have them inspected and potentially replaced when you get new tires to prevent future issues. 

Alternatives and considerations

• TPMS light on: If you don't replace the sensors, you will have to drive with the warning light on. Some regions may fail vehicle inspections if the light is illuminated. 
• Cost savings: You can save money by not replacing sensors, especially for seasonal tires. For example, some drivers skip replacement on their winter tires. 
• DIY vs. Professional: You can replace a single sensor if that's the only one that failed. If you're not comfortable doing it yourself, take your car to a professional. 

What is the average cost to replace TPMS sensors?

The average cost to replace TPMS sensors is between $\$50 and $200$ 200$200 per sensor, including parts and labor, but this can vary based on the vehicle, the type of sensor, and the service location. A full set of four sensors can cost between approximately $314$ 314$314 and $368$ 368$368, depending on the specific vehicle, with some estimates reaching over $900$ 900$900 at dealerships for all four. 
Factors influencing cost

• Vehicle: The make, model, and year of your vehicle affect the price. 
• Sensor type: You may pay more for specialized or OEM (Original Equipment Manufacturer) sensors, which are found at dealerships, compared to aftermarket sensors offered by independent shops. 
• Labor rates: Dealerships generally have higher labor rates than independent mechanics or tire shops, so a single sensor replacement at a dealership could cost $100−$300$ 100 minus $ 300$100−$300, while independent shops may charge $50−$200$ 50 minus $ 200$50−$200. 
• Installation: Some shops include installation with the sensor price, while others charge separately. The process involves removing the tire, installing the new sensor, and programming it to your car's system. 

Where to get a replacement

• Dealership: Expect higher prices, but you'll get OEM sensors and guaranteed compatibility. 
• Independent mechanic: Prices are often more competitive than at a dealership. 
• Tire shops: Many tire retailers offer a package that includes parts and labor, often with a warranty. For example, one tire shop quoted a price of around $60$ 60$60 per sensor, including installation. 

Is it necessary to replace all four?

• TPMS sensors are designed to last for several years, but their batteries can die, or they can be damaged over time. 
• If a sensor fails, it is often recommended to replace it while the tire is off the wheel to avoid having to pay for labor multiple times. 
• You can choose to replace only the failed sensor, but if other sensors are approaching their lifespan, replacing all four may be a good long-term investment.
