How often should I replace my TPMS sensors?
Direct TPMS sensors do not have a fixed replacement schedule. In practice, you replace them when they fail or when you install new tires, and the sensor battery typically lasts around 5 to 7 years, sometimes longer depending on usage and environment.
TPMS, or Tire Pressure Monitoring System, helps monitor tire inflation to improve safety, fuel economy, and tire wear. There are two types: direct TPMS sensors placed in each wheel that measure actual pressure, and indirect TPMS that infers pressure from wheel-speed data. Understanding which system you have informs your maintenance plan and replacement timing.
Direct TPMS sensors: lifespan and replacement expectations
It's important to know how long direct sensors last and what factors influence their life. Here is a quick guide to typical lifespans and the practical replacement timeline.
- Battery life is a major factor. Direct TPMS sensors contain a non-replaceable battery that commonly lasts about 5 to 7 years, though some may go 5 to 10 years or longer with light use and favorable conditions.
- Sensor durability varies by climate and road exposure. Extreme temperatures, salt, potholes, and corrosion at the valve stem can shorten service life.
- Most manufacturers require replacing the sensor when you install new tires or when the sensor is damaged during tire service. The battery in OEM sensors is not typically replaceable, so the entire sensor is replaced rather than serviced.
- Aftermarket sensors exist with replaceable battery designs, but these are less common on vehicles from some brands and may affect warranty.
In short, plan on sensors lasting several years, with replacement likely tied to tire service or failure rather than a fixed calendar interval.
When to replace TPMS sensors
Next, consider concrete scenarios that trigger a replacement decision. This list helps you decide when to replace the sensors rather than just monitoring the warning light.
- The TPMS warning light is on or readings are inconsistent across wheels, suggesting a failed sensor or a dead battery.
- You are replacing tires or wheels. Most shops replace sensors when tires are changed, because reusing a dead or near-dead sensor is inefficient and can lead to inaccurate readings.
- Visible damage or corrosion around the valve stem or wheel mounting area, which can compromise the seal and sensor integrity.
- The sensor was damaged in an accident or during tire service and cannot be reset or relearned properly.
- You are performing a tire replacement on a vehicle whose sensors are near the end of their expected life (roughly 5–10 years). A shop may recommend replacement to avoid repeated service calls.
These are the most common triggers for replacing TPMS sensors. If you’re unsure, a quick diagnostic from a tire shop or dealer can confirm whether a sensor is failing.
Relearn and calibration steps
After you replace sensors, most modern vehicles require a TPMS relearn procedure so the system recognizes the new sensor IDs. Procedures vary by make and model, but common methods include driving for a set period, using the vehicle’s onboard menu, or visiting a service center for a relearn. Check your owner's manual or ask your tire shop for the exact steps.
Cost considerations and long-term maintenance
Costs vary by vehicle and region. A direct TPMS sensor typically costs around $60–$100 per wheel, plus installation fees of roughly $10–$50 and a relearn charge if applicable. Labor adds another $20–$50 per wheel in many shops. Expect total per-wheel costs in the ballpark of $100–$250, with higher prices for premium OEM sensors or complex wheel configurations.
Maintenance tips: Regularly check tire pressures monthly, inspect valves for corrosion, and ensure proper tire sealing during replacements to maximize sensor life. When in doubt, have a professional inspect the TPMS after tire work or if warning lights illuminate.
Summary
TPMS sensors do not require annual replacement. They typically last several years, with direct sensors having a battery life around 5–7 years on average. Replace sensors when tires are replaced, when a sensor fails, or when the battery is near the end of its life. A relearn after installation ensures accurate readings. Planning for replacement based on tire service intervals and sensor condition can help avoid unexpected warning lights and keep tires properly inflated.
