What is a Tire Pressure Monitor Sensor and How Does It Work?

A Tire Pressure Monitor Sensor (TPMS) is a device that monitors the air pressure in tires. It alerts the driver when tire pressure falls below a specified limit, enhancing vehicle safety.

According to the National Highway Traffic Safety Administration (NHTSA), TPMS is crucial for reducing tire-related crashes by ensuring proper tire inflation.

TPMS functions by using sensors located within or attached to each tire. These sensors measure tire pressure and send data to the vehicle’s onboard computer. If tire pressure is too low, a warning light illuminates on the dashboard.

The Tire Industry Association defines the two main types of TPMS: direct and indirect. Direct TPMS uses pressure sensors inside each tire, while indirect TPMS estimates pressure through wheel speed data from the anti-lock braking system (ABS).

Factors affecting TPMS performance include temperature changes, tire wear, and changes in load capacity. Unattended, low tire pressure can lead to blowouts, poor fuel efficiency, and increased tire wear.

The NHTSA reports that properly inflated tires can improve fuel efficiency by 0.4% for every 1 psi drop in pressure. Under-inflated tires contribute to about 11,000 crashes annually.

Improperly inflated tires can cause accidents, increase greenhouse gas emissions, and generate more waste from premature tire replacements.

For effective TPMS function, the NHTSA recommends regular tire pressure checks, timely sensor replacements, and ensuring tires are properly inflated.

Implementing tire pressure monitoring systems can reduce accidents, enhance fuel efficiency, and promote environmental sustainability through lower emissions.
