Just as the rubber valve is renewed during tire service, individual components must be replaced with new ones for the tire pressure monitoring system sensor (TPMS sensor). Each time the tire is changed, the appropriate parts kit must be used to replace the wearing parts (nut, sealing ring, nickel-plated valve insert, dust cap). This is for safety, prevents failures and prevents larger and more costly consequential damage (e.g. complete replacement of sensor due to corroded valve insert). The TPMS service kits contain the necessary spare parts.
CAUSES OF FUNCTIONAL FAILURES
Corrosion of metal parts
Brittleness of the rubber seal
POSSIBLE CONSEQUENCES OF FUNCTIONAL FAILURES
Damage and replacement of the complete sensor
Loss of pressure in the tire
Flat tire
Loss of vehicle control
According to the specifications of the automobile manufacturers, the TPMS components must be checked and replaced every time the tires are changed.
