The control and/or diagnosis method provides a correction value for correcting the control of the mass flow and/or for providing a fault indication, obtained from the calculated line resistance of the mass flow line (50). Also included are Independent claims for the following: (a) a device for control and/or diagnosis of a mass flow control system; (b) a computer program for control and/or diagnosis of a mass flow control system; (c) a computer program product for a program for control and/or diagnosis of a mass flow control system Es werden ein Verfahren und eine Vorrichtung zur Steuerung und/oder Diagnose eines einen Massenstrom beeinflussenden Steuersystems vorgeschlagen. Dabei wird ein Korrekturwert gebildet, welcher die Steuerung korrigiert bzw. zur Diagnose ausgewertet wird. Der Korrekturwert wird dabei aus dem Leitungswidertstand der Massenstromleitung abgeleitet.
