Chevrolet Traverse TPMS Sensor

For what is known as the Tire Pressure Monitoring System (TPMS), tire pressure sensors are important to. A tire-pressure sensor is a small programmable electronic device located in a wheel and tire pressurised pocket which constantly measures the air pressure inside the tire. If air pressure drops 25 per cent below the prescribed level of the manufacturer, the sensor transmits this information to the onboard computer of the vehicle via low-frequency radio and displays it in the cluster of instruments. It reads in pounds per square inch (psi) and alerts an amber warning light when one or more tires are low on air. TPMS notifies when there is low or flat tire pressure in the vehicle. By helping to maintain proper tire pressure, TPMS can improve road safety by improving handling of the car, decreasing tire wear, reducing braking distance and improving fuel economy. TPMS-equipped tires cost slightly more to maintain than unequipped tires, as proper care requires additional parts and labour. The valve service package, which contains the valve heart, cap, nut and o-ring (seal), should always be replaced when a tire is removed for repair or replacement purposes. It also takes a special TPMS tool and additional time to inspect and reset the sensor system. A second type of tire-pressure monitoring system exists, which works completely differently. It does not use tire-pressure sensors in the tires, but relies instead on wheel-speed sensors from the anti-lock-breaking system to determine if the rotational speed of any particular tire is out of sync with the others. This indicates that the circumference of the suspect tire has changed, and that the air pressure could have been lost.

To help drivers understand the value of protection and maintenance at tire pressure. TPMS notifies when there is low or flat tire pressure in the vehicle. By helping to maintain proper tire pressure, TPMS can improve road safety by improving handling of the car, decreasing tire wear, reducing braking distance and improving fuel economy.

Tire-pressure sensors are typically attached to each tire's valve-system assembly and powered by batteries.
