Have you ever noticed the TPMS low tire pressure indicator, which is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe) with an exclamation point.
There are several reasons one should pay attention to this tire pressure icon, not the least of which is safety:
- Safety – An underinflated tire is more prone to a tire blowout, which can cause you to lose control of your vehicle. Additionally, underinflated tires don’t deliver traction while cornering, which can also lead to loss of vehicle control. Underinflated tires account for tens of thousands of crashes every year and over six hundred fatalities in the United States.
- Efficiency – Each year consumers in the USA alone consume close to 150 Billion gallons of fuel. It’s estimated that underinflated tires waste about two billion gallons of fuel each year, enough to power the United States’ automobile fleet for five days! On a personal level, this might translate to a few hundred dollars in fuel every year. Fleet operators could save tens of thousands per year.
- Longevity – Underinflated tires will wear unevenly, affecting ride quality and increasing the risk of a tire blowout. Also, underinflated tires wear out faster, which means you’ll replace them more often. You might get less than half the use out of a tire that isn’t inflated properly.
- Ride – Proper tire pressure is an important part of your vehicle’s steering and suspension. Whereas the shock absorbers absorb big bumps, tire pressure absorbs small ones and smooths out your ride. As tire pressure decreases, your ride gets softer, but also less certain, as the tires lose their directional stability.
The answer is the TPMS sensor which is normally installed in your tire.
In the event that the sensor detects that air pressure in a tire has dropped to a dangerously low level—25 percent below the recommended air pressure, according to federal government regulations—a warning message or light will display in the instrument cluster. Inflation pressure recommendations for the tires that originally come on a car can usually be found on a label on the driver's doorsill.
Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. So a TPMS sensor is typically replaced when its battery runs out.
Generally, TPMS sensors can be reset to 0 and recalibrated for your new tires automatically. But in some cases, after you replace some TPMS sensors in your tires you must manually remove the code in your car's computer and replace it with the code from the new sensor.
If you don’t want to do this at the shop, you can use a TPMS reset tool to reset the sensors on your own, like the newly-released X431 TSGUN from LAUNCH.
This is a Bluetooth TPMS add-on module, working together with Launch diagnostic scanners, with extensive vehicle coverage of Euro, Asian and America, to help expand new functions and generate new revenues for X-431 users.
