Zusammenfassung:	A method for controlling a valve including a spring, an actuator having an actuator force opposing the spring, and a pin actuatable by the actuator. To open the valve, in a first operating mode a current having a predefined curve is applied to the actuator, starting from a starting value of the current at which the pin is positioned to allow the valve to close, measured values of the current are determined chronologically sequentially, a reference value of the current takes on the current measured value of the current when the measured current deviates from the applied current by a predefined degree. In a second operating mode, a current having a predefined curve is applied to the actuator, starting with the starting value of the current to a final value of the current at which the pin is in a position that prevents the valve from closing.
