How Do Tire Pressure Monitoring Systems Operate?
A tire pressure monitoring system, also known as a tire pressure indication system (TPIS) is an electronic system that measures the air pressure in tires. The tire pressure monitoring system send the information about air pressure to a gauge or display on the dashboard, alerting the driver to a potential safety hazard. Tire pressure monitoring systems are common in American tires, especially in more modern cars. There are two types of tire pressure monitoring systems: direct and indirect. A direct sensor tire pressure monitoring system checks the pressure inside each tire with a pressure sensor that is attached to the tire’s air chamber. The direct sensor tire pressure monitoring system can gauge the amount of inflation in each individual tire. A direct sensor tire pressure monitoring system is built to take into account changes in pressure because of weather and road temperature changes. Car manufacturers set the systems to what they call a “cold placard inflation pressure.” Direct se
