How long do factory TPMS sensors last?
Factory-installed Tire Pressure Monitoring System (TPMS) sensors typically last between 5 to 10 years, depending on various factors. TPMS sensors are designed to monitor the air pressure in a vehicle's tires and alert the driver when the pressure drops below a certain threshold.
What is TPMS and How Does it Work?
TPMS is a safety feature that has been mandatory in all new passenger vehicles sold in the United States since 2008. The system consists of sensors installed in each tire that measure the air pressure and transmit the data to a central control unit. When the pressure in one or more tires drops below the recommended level, the TPMS warning light on the dashboard illuminates, alerting the driver to check and inflate the tires.
Factors Affecting TPMS Sensor Lifespan
The lifespan of a TPMS sensor can be influenced by several factors:
- Battery Life: TPMS sensors are powered by small batteries that have a limited lifespan, typically around 5 to 10 years.
- Environmental Conditions: Extreme temperatures, moisture, and exposure to road debris can all contribute to the degradation of TPMS sensors over time.
- Driving Conditions: Frequent high-speed driving, heavy loads, and rough roads can put additional stress on TPMS sensors, potentially shortening their lifespan.
- Maintenance: Regular tire rotations and wheel alignments can help extend the life of TPMS sensors by ensuring they are not subjected to excessive wear and tear.
It's important to note that the lifespan of TPMS sensors can vary depending on the specific make and model of the vehicle, as well as the individual sensor's quality and manufacturing.
Replacing TPMS Sensors
When a TPMS sensor fails, it will need to be replaced. This can be done by a professional mechanic or, in some cases, the vehicle owner. Replacement sensors can be purchased from the vehicle manufacturer or aftermarket suppliers. The cost of a TPMS sensor replacement can range from $50 to $150 per sensor, depending on the vehicle and the source of the replacement part.
It's important to note that TPMS sensors are an essential safety feature, and it's crucial to maintain them in good working order to ensure the proper functioning of the tire pressure monitoring system.
