Abstract

A method and a device are provided for operating an internal combustion engine, which make possible an improved characteristics curve correction of an actuator in an air supply of the internal combustion engine. In the process, an air mass flow supplied to the internal combustion engine is influenced via the actuator in an air supply. For the setting of an actuating position of the actuator having a specified, e.g., minimum, air mass flow, starting from a specified actuating position, the actuator is moved by an offset value of the actuating position. The offset value of the actuating position is corrected as a function of an offset value for the air mass flow.
