1. A non-transitory, machine-accessible storage medium having computer instructions and wherein the instructions are configured, when executed by a controller, to cause the controller to:
measure a first resistance of a first resistor associated with a first position sensor;
based upon the measured first resistance, select a first delta curve, the first delta curve describing differences between a nominal fuel valve position and a first measured fuel valve position associated with the first position sensor;
measure a second resistance of a second resistor associated with a second position sensor;
based upon the measured second resistance, select a second delta curve, the second delta curve describing differences between the nominal fuel valve position and a second measured fuel valve position associated with the second position sensor;
receive a first fuel valve position (FVP) from the first position sensor, and apply the first FVP to the first delta curve to obtain a first compensated FVP;
receive a second FVP from the second position sensor, and apply the second FVP to the second delta curve to obtain a second compensated FVP;
correlate the first compensated FVP and the second compensated FVP to obtain a final compensated FVP;
apply the final compensated FVP to a desired fuel valve position to obtain a final fuel valve position and apply the final fuel valve position to a fuel valve to control an operation of the fuel valve.
