摘要： In a method for testing the functional reliability of a fuel-tank venting valve which is provided in a tank system of a motor vehicle in particular, is connected to an intake manifold and is triggerable by a control unit, a pressure source is provided for testing the tank system for leaks by using excess pressure or a vacuum, and the test of the functional reliability of the fuel-tank venting valve is performed on the basis of at least one performance quantity of the pressure source. In order to achieve a short diagnostic time and a high degree of diagnostic certainty, the fuel-tank venting valve is triggered to open or close, and a certain change in pressure is implemented. The at least one performance quantity of the pressure source is detected, and a properly opening and closing fuel-tank venting valve is determined from the performance quantity thus detected.
