Abstract: A system and method for monitoring vehicle tire pressure. A tire monitor for each tire includes a pressure sensor for sensing tire pressure and a transmitter for transmitting a signal representative of the sensed tire pressure. A receiver for mounting on the vehicle receives the tire pressure signals. The transmitters and the receiver utilize code division multiple access (CDMA) for the tire pressure signals so that tire pressure signals transmitted simultaneously by the transmitters can be received by the receiver. A controller for mounting on the vehicle communicates with the receiver and collects and processes the tire pressure signals, and generates control signals for use in conveying tire pressure information to a vehicle occupant.
