Tpms Sensor Battery Life

Original equipment manufactured tpms sensors have an estimated battery life of 5 12 years with 7 years being the average.

Tpms sensor battery life.

Tpms sensors are equipped with permanent batteries. If the battery fails its time to replace the sensor unit. Very few sensors come with removable batteries so the lifespan of a tpms sensor is usually equal to its battery life. The lithium ion batteries inside tpms sensors may last anywhere from five to 10 years.

This means that eventually a complete replacement of the system will be necessary. Tpms sensor batteries have an estimated lifespan of 5 10 years or 100k miles. Due to their location tpms sensors can be damaged by flat tires accidents pot holes etc. Tpms sensors may suffer from corrosion typically due to road salt.

Tire pressure sensors are usually powered by 3 volt lithium ion battery or a 1 250 volt nickel metal hydride battery. In this video i ll show you how to replace toyota lexus tire pressure monitoring sensor tpms battery. If tmps battery is low then at the startup of vehicl. A tpms sensor includes the battery pressure sensor wireless transmitter and the fill valve for your tire all in one unit.

However it s important to understand that the service life of the lithium ion batteries inside tpms sensors can be 5 to 10 years. You don t need to replace your tpms sensors when buying new tires but it s often convenient to do so if the. Standardize sensors so they output battery life information and standardize scan tools so they display battery life he says. Mandated tpms systems were phased in from starting from 2007 so some of these vehicles sensors have been in service for five years it is highly likely that many of your factory equipped tpms sensors are running low on battery life and may expire very soon.

Unfortunately you can t just swap out the battery in your tpms sensor. Do i need to replace tpms when replacing tires. Tpms sensors don t broadcast a continuous signal but only broadcast when the vehicle is in motion. Five to six years is a more typical lifespan for older tpms sensors.

Even then the signal is intermittent to conserve battery life. He adds that the industry also should agree that a low or 15 readout is the proper time to recommend to customers that they replace all four tire sensors and recheck the spare if it is tpms equipped.
