What is a Tyre Pressure Sensor?
A tyre pressure sensor is a gadget that monitors the air pressure in a tyre. It is part of the Tyre Pressure Monitoring System (TPMS) that reports to the driver when a tyre pressure is low. When the pressure drops to a pre-set level, for example, 25% less than the minimum required tyre pressure, the sensor sends signals to alert the driver. The driver receives the message on the dashboard as a low-pressure warning light, a pictogram display, gauge reading or a warning beeping sound.
