tire pressure sensor fault. what do i need to do to eliminate this issue? on 2009 Ford F-150

the diagnostic warning display is non-stop. it doesnt say which tire, and all of the tires, including the spare have good pressure, yet the warning light display has a constant display, saying "TIRE PRESSURE SENSOR FAULT'.

Common problem which is one of the tire pressure sensors has failed and needs replaced. Otherwise, the alarm won't go away.
