ABSTRACT:
A method and a device are proposed for controlling and/or diagnosing a control system influencing a mass flow. In this context, a correction value is calculated, which corrects the controlling, or is evaluated for diagnostic purposes. The correction value, in this context, is derived from the line resistance of the mass flow line.
