1. A method for identifying a sensor location in an initiator based tire pressure monitoring system, the method comprising the steps of:
- activating at least one initiator directed to at least one sensor in a known tire location;
counting the number of transmissions sent during a predetermined period of time for each sensor responding to the at least one initiator;
ranking a plurality of potential sensor identifications based on the number of counted transmissions for each sensor in response to the at least one initiator;
assigning the potential sensor identification having the highest number of transmissions to the at least one sensor in the known tire location.

Abstract
A method and system for eliminating cross talk in a tire pressure monitoring system that ranks potential sensor identifications based on the number of times the sensors respond to an initiator. Upon determination of a sufficient separation between second and third ranked sensors, an assignment of the first and second ranked potential sensor identifications is made to the tire locations expected to respond to the initiator signal.

7. A method for identifying a sensor location in an initiator based tire pressure monitoring system for a vehicle having front right, front left, rear right, rear left tires and a spare tire, the method comprising the steps of:
-
activating at least one initiator directed to pressure sensors in predetermined tire locations; counting the number of transmissions sent in a predetermined period of time for each pressure sensor responding to the at least one initiator; establishing a potential sensor identification for each pressure sensor responding to the at least one initiator; ranking the potential sensor identifications based on the number of counted transmissions for at least first, second and third ranked potential sensor identifications, the potential sensor identifications being ranked based on the number of transmissions counted for each pressure sensor responding to the at least one initiator; assigning the first and second ranked potential sensor identifications to the locations associated with the predetermined tire locations. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A system for eliminating cross-talk among sensors in a tire pressure monitoring system when determining sensor locations in a vehicle, the system comprising:
-
a plurality of tire pressure monitoring sensors wherein each sensor is associated with a respective tire location on the vehicle; at least one initiator associated with at least one sensor for a tire in a predetermined location on the vehicle, the initiator for initiating a response from at least one sensor associated with the at least one tire; a control algorithm for assigning a potential sensor identification to a respective tire location on the vehicle, wherein the algorithm counts the number of times each of the plurality of sensors transmits a signal in response to the at least one initiator for a predetermined period of time, creates a ranking of potential sensor identifications according to the number of times each sensor responds to the initiator wherein each ranked sensor is assigned a potential sensor identification, and assigns a respective tire location to each potential sensor identification based on its rank. - View Dependent Claims (15, 16, 17, 18)
