Understanding TPMS Sensors

TPMS stands for Tire Pressure Monitoring System, a crucial safety feature in modern vehicles that continuously monitors the air pressure in the tires. Properly inflated tires are essential not just for tire longevity but also for optimal car performance and safety.

TPMS uses sensors located within each tire to measure the air pressure and send real-time data to the vehicle’s onboard computer. If the tire pressure drops below a certain threshold, the system alerts the driver through a warning light on the dashboard. Understanding how TPMS sensors work and their components is vital for every car owner.

How Do TPMS Sensors Work?

There are two types of TPMS sensors: Direct and Indirect.

• Direct TPMS: This type uses pressure sensors mounted inside the tire to measure the pressure directly. They provide real-time data and can accurately trigger warnings for low tire pressure.
• Indirect TPMS: Instead of using pressure sensors, this system relies on the anti-lock braking system (ABS) to measure the rotational speeds of the wheels. A decrease in tire size, due to low pressure, results in a change in the wheel speed that triggers a warning.

Key Features of TPMS Sensors
