A method and a device for operating an internal combustion engine, e.g., of a motor vehicle, may permit a most accurate possible determination of a value for the flow-through area, e.g., the effective flow-through area, of a component arranged in a gas channel. The internal combustion engine has an adjustable component through which a gas flows and by whose setting the gas flowing through is influenced. At least one first value representative of a flow-area of the component, e.g., the effective flow-through area, is determined in accordance with a first model as a function of a triggering signal of the component. At least one second value representative of the flow-through area of the component, e.g., the effective flow-through area, is determined in accordance with a second model as a function of at least one performance quantity of the internal combustion engine different from the triggering signal. A resulting value is formed for the flow-through area, e.g., the effective flow-through area, as the mean of the at least one first value and the at least one second value.
