Claim 6:
7. A system for diagnosing a sensor, comprising:
a positive voltage and a negative voltage, wherein the sensor comprises a circuit comprising a plurality of Wheatstone bridge circuit elements and is powered by the positive voltage and the negative voltage and reacts to at least one condition by a first sensor signal and a second sensor signal, wherein the sensor is powered with elevation to avoid a saturation, wherein the first sensor signal and the second sensor signal provide a corresponding an amplitude with respect to the at least one condition, and wherein a plurality of sensor signals is output from the sensor, the plurality of sensor signals including at least the first sensor signal and the second sensor signal, the at least one condition comprising at least one of a first condition, a second condition or a third condition among a plurality of conditions, wherein a first Wheatstone bridge element among the plurality of Wheatstone bridge elements is most sensitive to the first condition, a second Wheatstone bridge element among the plurality of Wheatstone bridge elements is most sensitive to the second condition; and a third Wheatstone bridge element among the plurality of Wheatstone bridge elements is most sensitive to the third condition;
an analog-to-digital converter that receives the plurality of sensor signals output from the sensor;
a microcontroller that communicates electronically with the analog-to-digital converter and which differentiates from among the plurality of sensor signals to distinguish inequalities in the plurality of sensor signals for an indication of a potential fault in the sensor;
wherein the microcontroller is configured to:
identify a smaller sensor signal with respect to a larger sensor signal among the first sensor signal or the second sensor signal of the plurality of sensor signals for the indication of the potential fault in the sensor; and
differentiate the smaller sensor signal from the larger sensor signal to indicate a large difference between the plurality of sensor signals to render detection of the potential fault in the sensor.
