In this video i ll show you how to replace toyota lexus tire pressure monitoring sensor tpms battery.

Tpms sensor battery life.

Tire pressure sensors are usually powered by 3 volt lithium ion battery or a 1 250 volt nickel metal hydride battery. Due to their location tpms sensors can be damaged by flat tires accidents pot holes etc. The lithium ion batteries inside tpms sensors may last anywhere from five to 10 years. Tpms sensor batteries have an estimated lifespan of 5 10 years or 100k miles.

However it s important to understand that the service life of the lithium ion batteries inside tpms sensors can be 5 to 10 years. Even then the signal is intermittent to conserve battery life. If tmps battery is low then at the startup of vehicl.

If the battery fails its time to replace the sensor unit. Here s what an average tpms sensor looks like. Unfortunately you can t just swap out the battery in your tpms sensor.

Very few sensors come with removable batteries so the lifespan of a tpms sensor is usually equal to its battery life. Standardize sensors so they output battery life information and standardize scan tools so they display battery life he says. A tpms sensor is typically replaced when its battery runs out. Tpms sensors are equipped with permanent batteries.

Five to six years is a more typical lifespan for older tpms sensors. Do i need to replace tpms when replacing tires.
