The battery in the tire push sensors commonly last 7-10 year or 100,000 miles.

An exact tire push gauge and also manual air press checks should be part of a routine, and the TPMS alert regarded as a warning because that a serious condition. 

Other TPMS Considerations

Direct TPMS sensor batteries ultimately die and aren’t replaceable. Tire sealants and corrosion indigenous a weak or dead battery can likewise force a replacement. This sensors should be serviced through a professional due to the fact that the car must it is in programmed to acknowledge the new sensors.

Internal tire pressure fluctuates with temperature. A weather change may reason enough of a press drop to trigger the TPMS light. A TPMS warning because of a tiny temperature drop deserve to indicate the the tires is close to the reduced limit that the recommended pressure.
