The output of a wheel speed sensor is sampled at dithered time intervals and the samples used to construct a pair of histograms representing high and low sample values. A minimum voltage threshold is determined as a. function of the output voltage associated with the dominate histogram value for the low sample values. The output voltage associated with the dominant histogram value for the high sample values is compared to the minimum voltage threshold to determine whether a potential sensor wiring problem is developing.
