1. A vehicle tire pressure monitoring system comprising:

  • a tire pressure transducer;

    an electromagnet system supported on a vehicle wheel or tire in electrical communication with the tire pressure transducer, the electromagnet system configured to periodically send single bits of a code representing a tire pressure measured by the transducer;

    a sensor system supported by the vehicle body configured to receive individually the single bits of the code periodically sent from the electromagnetic system; and

    an electronic control unit that receives the code from the sensor system and converts the code into pressure information,wherein only one bit of the code representing the tire pressure measured by the transducer is received by the sensor system upon each revolution of the vehicle wheel or tire.
