Best Answer

If the light is flashing, then you have a problem with one of your sensors (the computer is not receiving a sensor signal), then you'll have to take your car to any Toyota dealer to check/repair your tire pressure sensors.

If the tire light keeps coming on constantly, it's probably because at least one of your tires has a leak, take your vehicle to a tire shop to check/fix/replace your tires.

Those sensors are very sensitive, so even if the tire had lost just a little air the light could come on, don't freak out you should be okay, but the light is very annoying!
