Abstract: A rotary movement position sensor is presented that includes a first sensor output, a second sensor output, a first signal processing unit, a second signal processing unit, a first system output providing the output of the first signal processing unit or of the second signal processing unit, and a second system output providing the output of the second signal processing unit or of the first signal processing unit. A swapping unit that swaps the first signal processing unit between the first sensor output and first system output to the second sensor output and second system output and simultaneously swaps the second signal processing unit from the second sensor output and second system output to the first sensor output and first system output and vice versa. A method for detecting errors in a position sensor system is also presented.
