Abstract
A method of checking the functional reliability of a pressure sensor, the air pressure being detected inside a vehicle body part, the vehicle having at least one additional pressure sensor for detecting the air pressure. With the help of the method, it may be possible to determine the integrity of the sensor without requiring any additional auxiliary equipment. To do so, the measured values of the pressure sensor and the measured values of the at least one additional pressure sensor are compared over a defined observation period. The pressure sensor is recognized as being defective if its measured values deviate by more than a predefined amount from the measured values of the at least one additional pressure sensor.
