Chevrolet Equinox TPMS Sensor
About TPMS Sensor
Tire-pressure sensors are small programmable electronic devices that are an integral part of the Tire Pressure Monitoring System (TPMS). A tire pressure sensor is located in the pressurized pocket made by a wheel and tire, which constantly measures the tire's air pressure. The sensor transmits when air pressure drops 25% below the manufacturer's recommended level through low-frequency radio to the vehicle's onboard computer and display the tire pressure on the instrument in psi alerting with an amber warning light about tires with low air. TPMS helps to maintain tire pressure and notifies the low or is going flat of the vehicle's tire pressure, increasing safety on the road. TPMS improves vehicle's handling, decreases tire wear and tear, reduces braking distance, and increases fuel economy. TPMS installed tires are more expensive and require more maintenance. Replace the valve service kit, which includes valve core, cap, nut, and o–ring (seal), must be replaced when a tire is replaced for service or replacement. To check and reset the sensor system requires a special TPMS tool and additional time. The second type of tire-pressure monitoring system works entirely adversely, which is not equipped with tire-pressure sensors in the tires. This type relies on the anti-lock-braking system's wheel-speed sensors to determine if any particular tire's rotational speed is out of sync, indicating the change in tire's circumference and loss of tire's air pressure.
What is the purpose of TPMS Sensor?
To help drivers recognize the importance of securing and maintaining tire pressure. TPMS notifies when there is low or flat tire pressure on the vehicle. Through helping to maintain proper tire pressure, TPMS can boost road safety through improving the handling of the car, decreasing tire wear, reducing braking distance and increasing fuel economy.
How TPMS Sensor Works?
A tire-pressure sensor is a small programmable electronic device located in a wheel and tire pressurized pocket, which constantly measures the air pressure inside the tire. When the air pressure drops by 25 percent below the recommended 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 if one or more tires are low in air.
Where is TPMS Sensor Located?
Tire-pressure sensors are normally mounted on each tire's valve system assembly and powered by batteries.
