Abstract: A method of testing a sensor device includes a single angle calculator and at least two magnetic sensor elements. The method includes 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; d) applying a second input value IN2 derived from the digitized signal, to the angle calculator, to obtain a second angle value; e) performing a consistency test of the first and second angle value; f) detecting an error of the sensor device or the angle calculator based on an outcome of the consistency test.
