Description

The Tire Pressure Monitoring System (TPMS) monitors the air pressure and temperature inside the tires to warn the driver of pressure changes that may affect vehicle performance. The TPMS control module analyzes wireless information. In other words, the system determines the tire air pressure and warns the driver if the tire air pressure drops below the standard level. Low tire pressure warning light on the instrument panel.
