Abstract
A method and a device for pressure sensor diagnosis in a tank venting system of a motor vehicle operated by an internal combustion engine is disclosed. The tank venting system includes an activated carbon filter, a purge line arranged between the activated carbon filter, and an intake tract of the motor vehicle. A tank venting valve is arranged in the purge line and a pressure sensor is arranged in the purge line. The method includes measuring a pressure prevailing in the purge line by way of the pressure sensor to determine a starting pressure, classifying the starting pressure into one of a plurality of pressure ranges depending on the amplitude of the starting pressure, and carrying out a pressure sensor diagnosis using a diagnosis algorithm which is associated with the pressure range in which the starting pressure lies.
