Abstract
A method for diagnosing a malfunction of a sensor system in an air system of an internal combustion engine, said sensor system comprising a first air state sensor, a second air state sensor and a third air state sensor, wherein a first value and a second value of a first comparison variable are ascertained in two different ways in an overall calculation step such that the result of a comparison between the first value and the second value is a function of each of the output variables of the first, second and third air state sensors and wherein in a fault detection step, said method recognizes as a function of the comparison between said first value and said second value of the comparison variable that a fault exists in the sensor system.
