Abstract
A tire inflation pressure monitoring system ( ) and a method for monitoring air pressure within a tire ( ) are provided. The system ( ) includes a tire based unit ( ) for sensing air pressure within the tire ( ) and for transmitting a pressure signal indicative thereof. The system ( ) also includes a vehicle based unit ( ) for receiving the pressure signal and for comparing the pressure signal to a predefined pressure range. The vehicle based unit ( ) is operable in one of (i) a normal operating mode that outputs an alert signal in response to the air pressure within the tire ( ) being outside of the predefined pressure range and (ii) a pressure gauge operating mode that outputs an in-range signal in response to the air pressure within the tire ( ) being within the predetermined pressure range.
