Abstract

A method for detecting a jammed charge movement flap of an internal combustion engine, a volumetric air flow of the internal combustion engine being ascertained as a measured volumetric air flow and as a modeled volumetric air flow. In the event of a deviation of the measured volumetric air flow from the modeled volumetric air flow which is greater than a predefined value, a jammed charge movement flap is automatically detected.
