Modern vehicles equipped with a tire pressure monitoring system, or TPMS for short, are an increasingly common sight these days. In fact, your Toyota or Scion model likely has one installed at the factory. Their role is to relay real-time tire pressure information to the driver, whether through a gauge, low-pressure warning light, or display.

A tire pressure monitoring system improves your driving in many ways. First, they help limit the increased tire wear that can come about due to under-inflated tires. Second, they improve fuel economy. Lastly, and most importantly, they help to prevent accidents caused by improperly inflated tires.

Before TPMS became commonplace, drivers had to get out of their vehicle, crouch down, unscrew the stem cap, and use a tire gauge to check their tires' air pressure. Not only is that inconvenient, but it's also messy work. A tire pressure monitoring system cuts down on the number of times you need to do that, since it's designed to alert you once the tire pressure gets low. You only need to check the pressure once that warning light triggers.

How To Spot A Failing Tire Pressure Monitor System

Early warning is the best way to avoid a flat tire or significant rim damage. Unfortunately, sometimes even the best TPMS can go bad. Signs of trouble include:

The dash warning light comes on, flashes repeatedly, and then turns off

Uneven tire wear

Strange noises coming from your wheels

Your steering wheel jerks from one side to the other

Worsening fuel economy, even those the TPMS light did not come on
