Abstract: A method is provided for cancellation of error between digital electronics and a non-ratiometric sensor. The method includes the steps of reading a voltage from a non-ratiometric sensor by digital electronics on a periodic basis for a predetermined time period, determining whether the voltage reading is between a predetermined range, and calculating a calibration (CAL) value based on the voltage reading if the voltage reading is between the predetermined range. The method also includes the steps of ending the previous steps when the predetermined time period has elapsed. The method further includes the steps of delaying for another predetermined time period after the step of ending and adjusting subsequent voltage readings from the non-ratiometric sensor based on the CAL value.
