Abstract

A method for testing the operability of a tank shutoff valve of a fuel tank system which is controlled by valves includes performing defined triggering of the tank shutoff valve and simultaneous introduction of an overpressure or partial vacuum into the fuel tank system via a pressure source, and the operability of the tank shutoff valve is determined on the basis of a variable which characterizes the introduction of the overpressure or partial vacuum.
