1. A method for determining an operational state of a fifth wheel, the method comprising:
sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component that moves as the fifth wheel locks onto a kingpin of a towed vehicle;

comparing the position vector to a threshold position; and
determining the operational state of the fifth wheel based on the comparison of the position vector to the threshold position.
