Abstract
A method for avoiding misdetection in a diagnosis of a tank venting system for a motor vehicle includes deriving a statement about a fill level of a fuel tank by evaluating a signal of a pressure sensor in the tank venting system. To that end, prior to the diagnosis of the tank venting system, the pressure fluctuations are detected and compared with a threshold value. If the pressure fluctuations exceed the threshold value, then a conclusion is drawn that the fuel tank is full, and the diagnosis is not enabled.
