How To Test Tpms Sensor Battery

Playing an important role in tire pressure monitoring system tire pressure sensors help you to warn about the under inflated or over inflated tires in your vehicle there are basically two kinds of tire pressure monitoring system direct tpms dtpms and indirect tpms itpms.

How to test tpms sensor battery.

Put the key in the ignition and turn it to the on position but do not start the car. These sensors collect information and send it to the car s on board computer. This tpms sensor uses a lithium battery with a five to 10 year. The battery is encased in the sensor s molded plastic housing.

Each tire has a sensor. First the system. When this warning lamp illuminates on your instrument panel at least one of your tires is 25 percent below its correct pressure. A battery that is running low on or is depleted requires the replacement of the entire tpms sensor assembly.

Rigney cautions that it s difficult to interpret the scanned data because the readout could be a battery life percentage or a one. Tire pressure monitoring sensors are usually powered by a 3 volt lithium ion battery. Use your vehicle s tpms reset button. There are a couple of ways to check the system.

However the direct tpms is most likely to malfunction due to bad weather conditions. Some tpms sensors use a 1 250 volt nickel metal hydride battery. It is usually found in cars in the united states. The indirect tpms has sensors placed on the car s abs brakes and or the speed sensors on each wheel.

Tire pressure sensors work with the tire pressure monitoring system on many passenger vehicles. Sometimes the sensor system simply needs resetting.
