A tire pressure monitoring system ( 12 ) for a vehicle ( 10 ) has a plurality of tires ( 14 A-D) in respective rolling locations having a respective plurality of tire transmitters ( 16 A-D) that generate a respective plurality of transmitter identification signals. A respective plurality of initiators ( 20 A-D) are fixedly attached to the vehicle at a respective plurality of locations. The initiators may include orthogonal coils ( 112, 114 ). A controller ( 22 ) activates the plurality of initiators using the coils ( 112, 114 ) and receives a plurality of respective sensor signals having respective tire identifications. The activations may occur with a duty cycle of less than about fifty percent.
