Abstract
Various methods for determining the fully closed position of a wastegate valve are provided. In one example, a non-closed position command for a wastegate valve in a low-lift region relative to a valve seat is received. Prior to executing the position command, the wastegate valve is only temporarily closed to thereby determine a fully closed position.
