Zusammenfassung:Method of testing a sensor device that comprises a single angle calculator and at least two magnetic sensor elements, comprising the steps of: a) obtaining signals from the sensor elements; b) amplifying and digitizing the signals from the sensor elements; c) applying a first input value (IN1) derived from the digitized signal, to the angle calculator, to obtain a first angle value (α); d) applying a second input value (IN2) derived from the digitized signal, to the angle calculator, to obtain a second angle value (β); e) performing a consistency test of the first and second angle value (α, β); f) detecting an error of the sensor device or the angle calculator based on an outcome of the consistency test.
