An angular position sensor is provided by disposing two sensors proximate a rotatable member. A stationary sensor is located in a fixed position and a movable sensor is pivotable about the center of rotation of the rotatable member. A software routine uses a first output signal from the stationary sensor to calculate the rotational speed of the rotatable member. The software also determines a time offset between the receipt of a signal pattern by the stationary sensor and a subsequent receipt of the same pattern by the movable sensor. Using this time offset and the rotational speed of the rotatable member, the angular difference between the positions of the movable and stationary sensors can be developed. This angular difference is equivalent to the throttle position.
