Abstract
A method of monitoring a position sensor includes calculating an absolute value of a sine signal and an absolute value of a cosine signal from the position sensor. At least one of the absolute value of the sine signal and the absolute value of the cosine signal is compared to a minimum threshold to determine if the at least one of the absolute value of the sine signal and the absolute value of the cosine signal is less than the minimum threshold, or if the at least one of the absolute value of the sine signal and the absolute value of the cosine signal is equal to or greater than the minimum threshold. A fault with the position sensor is indicated when the at least one of the absolute value of the sine signal and the absolute value of the cosine signal is less than the minimum threshold.
