Abstract
A system and method is provided for calibrating a position sensor having a variable output corresponding to the variable position of a movable member. The system and method establishes for the position sensor a first output corresponding to a first given position of the movable member. The system and method stores the first output from a first operating session in memory to use in establishing the first output for a second operating session. The system and method may also use a biasing factor in establishing the first output for a second operating session. The system and method may also establish a second output corresponding to a second given position of the movable member as a function of a second output from a previous operating session or as a function of a biasing factor. The system and method may be used to control an internal combustion engine.
