Claim Text:
1. An oxygen sensor pressure compensation system, comprising a static pressure compensation module configured to (i) receive an oxygen sensor signal from an oxygen sensor and a pressure signal from a pressure sensor, (ii) retrieve a correction factor based on the pressure signal, and (iii) apply the correction factor to the oxygen sensor signal to generate a static pressure compensation signal, wherein the static pressure compensation signal corresponds to a static pressure as measured by the pressure sensor; a dynamic pressure compensation module configured to (i) receive the pressure signal, (ii) generate a dynamic pressure compensation signal based on the pressure signal, wherein the dynamic pressure compensation signal corresponds to a change in the pressure signal from a previously received pressure signal; and a summing module to configured to combine the static pressure compensation signal and the dynamic pressure compensation signal to generate a compensated oxygen signal.
