Abstract

A fuel tank system has a fuel tank and a storage element. In monitoring the fuel tank system, to check the sealing action of the fuel tank system at regular intervals during driving of the motor vehicle, a first valve is arranged in the first line upstream of the storage element as viewed in the direction of the fresh-air flow, an air pump is arranged between the first valve and the storage element, and a second valve is arranged in the second line between the storage element and the intake line. A mass flow sensor is arranged in the first line between the first valve and the storage element.
