Abstract

A method and device for self-test of a sensor. The method includes stimulating the sensor with signals that generate sensor outputs at a frequency that differs from the frequency of expected sensed parameter signals. The sensor output is filtered to remove the effects of the stimulation inputs, generating a sensed parameter signal. The unfiltered sensor output is compared to the expected output of the sensor with the stimulus input. A malfunctioning sensor may be detected by the comparison and appropriate action may then be taken.
