TPMS – Tire Pressure Monitoring System –

TPMS directly measures tire pressure using hardware sensors. In each wheel, most often on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit which reports it to the vehicle’s onboard computer. Some units also measure and alert temperatures of the tire as well. These systems can identify under-inflation for each individual tire. Although the systems vary in transmitting options, many TPMS products (both OEM and aftermarket) can display realtime, individual tire pressures whether the vehicle is moving or parked.
