The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Some units also measure and alert temperatures of the tire as well. These systems can identify under-inflation in any combination, be it one tire or all, simultaneously.
A tire pressure monitoring system â called TPMS â consists of sensors on each wheel that measure tire pressure. If tire pressure drops 25 percent below the manufacturerâs recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard.
