Abstract

A method for testing a supercharger actuator for a supercharger of a supercharged internal combustion engine, including adjusting the supercharger actuator from a first position to a second position, determining a rotational speed change information, which is a function of the change of the rotational speed of the supercharger resulting from the adjustment, and establishing a malfunction of the supercharger actuator as a function of the rotational speed change information.
