Abstract

The invention relates to a diagnostic method for an electromechanical actuator, particularly for a piezo actuator of an injector of an injection system, comprising the following steps:at least one operating variable of the actuator is determined and a parameter of the actuator is determined according to the electric operating variable, said parameter being dependent upon the force acting upon the actuator. According to the invention, the electric operating variable is the effective electrical resistance of the actuator.
