A TPMS, or Tire Pressure Monitoring System, is an electronic system employed in most modern vehicles to monitor the air pressure inside your tires. This system is vital in ensuring the safety and maintenance of tires. In fact, Congress implemented the TREAD Act in 2000 to ensure that all vehicles made in 2006 and after that are equipped with TPMS. How Does TPMS Operate? There are two main types of systems used in vehicles today: Direct TPMS and Indirect TPMS Direct TPMS - This type uses sensors within each tire that monitor specific pressure levels, not from the anti-lock brake system. When air pressure falls 25% under the manufacturer's recommended level, the sensor transmits the data to your vehicle's computer system and triggers your dashboard TPMS light to come on. Indirect TPMS - This type of system works with your vehicle's Anti Lock Braking System's (ABS) wheel speed sensors. If a tire's pressure is down, it will roll at a different wheel sp ... read more
