Vehicles with the tire pressure monitoring system (TPMS) may experience a situation where the warning light is on, yet the tire pressures are correct. One possibility is that the pressure sensors have "gone to sleep" and need to be reset. There is a reset tool available, or you can have a shop reset the sensors. Have the shop refer to the Ford TSB-06-3-7.
