In a method for checking the tightness of a tank-venting system of a vehicle, one tightly closes the tank by means of a blocking device after shutting off the vehicle. Thereafter, one detects the pressure, which develops in the tank system, with a pressure sensor and draws a conclusion as to a leak based on the pressure trace over time. An arrangement for checking the tightness in accordance with this method is suggested.
