1. An automotive tire pressure monitoring assembly (10) for use in an automobile (12) including at least one noise generating assembly (12) actively radiating a spectral noise signal comprising:

  • at least one tire pressure sensor (34) generating a pressure signal (50) based on the pressure of air within a tire (14), said tire pressure sensor (34) including a sensor receiver (68) in communication with a sensor control logic (38), said sensor control logic (38) adapted to receive the spectral noise signal (20) from the at least one noise generating assembly (18);

    a controller assembly (52) positioned within the automobile (12) and in remote communication with said at least one tire pressure sensor (34); and

    a positioning logic adapted to determine the position of said at least one tire pressure sensor (34) based on the strength of the spectral noise signal (20).
