Abstract
A method for diagnosing a sensor unit of an internal combustion engine, in which an output signal of the sensor unit is compared to a setpoint value which is specified independently from the output signal. The setpoint value relates to a periodic characteristic, and the variation over time of the value of the output signal of the sensor unit or a variable which is derived from the value variation over time is analyzed with regard to this periodic characteristic.
