Abstract
A method for diagnosing errors in the correct operation of a sensor system. A positive signal amplifier saturation threshold value and a negative signal amplifier saturation threshold value less than the positive signal amplifier saturation threshold value are provided, and at least one signal comparator threshold value. A current value of a first amplified input signal at a first time is provided and a current value of a second amplified input signal obtained at a second time later than the first time, but in the same measurement cycle. The measured values of the first and second amplified input signal are compared to the current signal comparator threshold value. A new output state is determined via the measured first and second amplified input signals. From a previous comparison of the first and second amplified input signal a current output state is provided, from which an expected new output state is determined.
