A system for determining vehicle direction includes an active wheel speed sensor (aWSS), an exciter ring for inducing a change in a signal from the aWSS and a controller. The controller receives a first series of signals from the aWSS, compares them to an array of predefined signals and determines the direction of travel based on the first series of signals matching the array. The controller receives a second series of signals and determines the exciter ring has an anomaly in response to at least one signal in the second series of signals having a first variance. The controller updates the array of predefined signals to include a representation of the first variance to create an array of updated signals. The controller determines the direction of travel based on a subsequent series of signals matching one of the array of predefined signals and the array of updated signals.
