Abstract: An automotive tire pressure monitoring system is provided including a group of tire pressure monitor sensors each comprising a pressure sensor element, a dual-axis accelerometer, and a transmitter generating a pressure signal including accelerometer information. A front antenna and a rear antenna are both in communication with a tire pressure monitoring receiver. The tire pressure monitoring receiver includes logic adapted to: determine a pressure signals left/right designation from the accelerometer information and determine a pressure signal's front/rear designation using comparative signal strength from the front antenna and the rear antenna.

Abstract: A tire pressure monitor system is provided including a sensor housing forming an internal housing mount chamber. An air inlet port is formed on a housing side surface and is orientated parallel to the wheel rim rotational axis. A sensor assembly including an air pressure sensor element is mounted within the internal housing mount chamber. A filter element and a gasket element are positioned between the air pressure sensor element and the air inlet port. A potting material fills the internal housing mount chamber. The filter element and the gasket element creating an air pressure flow path from the air inlet port to the air pressure sensor element.
