Claim 13:
14. The method of claim 12, wherein the calibration value is determined by:
identifying a pressure sensor calibration equation that includes calibration coefficient values previously determined in a calibration of the pressure sensor;
identifying temperature measurements of the pressure sensor and corresponding sensor error measurements for the pressure sensor, wherein each temperature measurement of the identified temperature measurements was measured when the pressure sensor made a corresponding measurement of pressure that was used to determine a corresponding sensor error measurement of the identified sensor error measurements;
determining calibration coefficient adjustment values by performing a polynomial fit using the identified temperature measurements and corresponding sensor error measurements;
determining an adjusted pressure sensor calibration equation by using the calibration coefficient adjustment values to adjust the previously determined calibration coefficient values of the pressure sensor calibration equation; and
determining the calibration value using the adjusted pressure sensor calibration equation.
