Abstract
A system is provided for calibrating a position sensor having a variable output corresponding to the variable position of a movable member. The system establishes, for the position sensor an original assumed output corresponding to a given position of the movable member, establishes for the position sensor a maximum output corresponding to the given position, the maximum output being greater than or equal to the assumed output, establishes for the position sensor a minimum output corresponding to the given position, the minimum output being less than or equal to the assumed output, determines an actual output of the position sensor and, if the actual output is between the maximum output and the minimum output, the system reestablishes the assumed output as being a function of the original assumed output and the actual output.
