A vehicle wheel hub assembly includes an outer member configured to be mounted to a non-rotatable portion of the vehicle and an inner member rotatably supported in the outer member by a bearing and configured to support a vehicle wheel. A first target member is coupled with the inner member, and a first sensor is fixed to the outer member and positioned to sense an angular displacement of the first target member relative to the outer member and to produce a first output signal. A second target member is coupled with the inner member and is spaced axially from the first target member, and a second sensor is fixed to the outer member and positioned to sense an angular displacement of the second target member relative to the outer member and to produce a second output signal.
