Why won’t my tire pressure light go off?
If your TPMS light remains on after inflating the tires to the proper pressure, try these steps: Drive the car at 50 mph for about 10 minutes. This should reset the tire sensors, and the next time you start the car the TPMS light should be off.
How do I clear the tire pressure light?
You should only attempt to reset the light after first addressing the tire pressure in every tire. Once your tires are at the appropriate pressure, the light may go off on its own. If it doesn’t go off right away, driving at 50 mph for about 10 minutes should help the tire pressure sensor reset.

How does TPMS know which tire is which?
These sensors measure the rate of revolution each wheel is making and can be used by on-board computer systems to compare with each other and to other vehicle operation data such as speed. Based on the rate of revolution of each wheel, the computer can interpret the relative size of the tires on your vehicle.
