Claim 10:
11. A method for position sensing and diagnostic comprising:
providing a source current to at least one magneto-sensitive element;
generating at least one analog sensor signal by the at least one magneto-sensitive element;
converting the at least one analog sensor signal or a signal derived from the at least one analog sensor signal into a digital sensor signal;
calculating a position signal as a function of the digital sensor signal or the signal derived from the digital sensor signal;
comparing a magnitude signal that is calculated as a function of the digital sensor signal or the signal derived from the digital sensor signal and/or the position signal with a target signal;
controlling the source current as a function of a stimulus signal that is provided as a function of a stimulus pattern,
wherein the stimulus pattern is a predetermined pattern and wherein the controlling is performed during a diagnostic phase;
setting the source current as a function of a gain control signal that is a function of the comparison of the magnitude signal and/or the position signal and the target signal, wherein the setting is performed during an operating phase for position sensing.
