Abstract
A soot sensor system and a method of sensing soot in a vehicle soot sensor system. The soot sensor system and method includes providing a soot sensor having at least one trace of conductive material in a continuous loop on a surface of a substrate, applying an alternating current (AC) input voltage to the at least one trace of conductive material to establish an AC sense current through the at least one trace of conductive material, and generating, using a peak detector, a peak detector output voltage representative of a peak value of the AC sense current and of an amount of soot accumulated on the soot sensor.
