Understanding Tyre Pressure Monitoring Systems

Tyre pressure monitoring systems (TPMS) are key to vehicle safety. They use sensors to check tire pressure and temperature. This gives drivers real-time data to avoid accidents.

Proper tire pressure lowers the chance of blowouts and flats. It also boosts fuel efficiency and car performance.

There are two main types of TPMS: direct and indirect. Direct TPMS has sensors inside the tire for pressure checks. Indirect TPMS uses the car’s ABS to guess tire pressure. Direct TPMS is more accurate but costs more than indirect TPMS.

What is a TPMS?

A TPMS is an electronic system that watches tire pressure. It warns the driver if pressure gets too low. This stops underinflation, which harms safety, fuel use, and tire life.

How TPMS Technology Works

TPMS technology uses sensors to keep an eye on tire pressure and temperature. These sensors send data to a control unit. The unit shows the info on a dashboard screen.

If tire pressure drops too low, the system alerts the driver. This is done with a warning light or message.

Types of TPMS Available

There are several types of TPMS, including:

  • Direct TPMS: uses sensors inside the tire to measure pressure
  • Indirect TPMS: uses the vehicle’s ABS to estimate tire pressure
  • Hybrid TPMS: combines elements of both direct and indirect TPMS

Regular TPMS calibration is key and done during vehicle service. Sensors need replacing if they run out of battery, malfunction, or get damaged. Knowing how TPMS works and the different types helps drivers see its importance. It ensures their system is working right.
