Abstract

A method of diagnosing a valve is described, which has an electrodynamic actuator, which includes a coil, a movable magnet arrangement for generating a magnetic field, and a movable control element which is coupled to the movably arranged magnet arrangement. At least one electrical variable of the electrodynamic actuator is measured. The electrical variable is evaluated with respect to a reference variable to determine at least one induction-dependent valve variable which is assigned to the motion profile of the electrodynamic actuator. A diagnosis module and a valve are furthermore described.
