1. A method of increasing a weighting factor of an exponentially weighted moving averaging (“

  • EWMA”

    ) filter, comprising;

    monitoring a data stream containing raw data values and determining an EWMA value based on the data stream by an electronic control module including operative logic;

    determining if the EWMA value is between a predetermined maximum fault threshold value and a predetermined minimum fault threshold value; and

    increasing the weighting factor of the EWMA filter to an adjusted weighting factor to more heavily weigh incoming raw data values of the data steam based on the difference between the first raw data value and a previously calculated filtered data value exceeding the calibration value.
