Abstract
An oxygen sensor pressure compensation system includes a static pressure compensation module to receive an oxygen sensor signal from an oxygen sensor and a pressure signal from a pressure sensor and to perform static pressure compensation. A dynamic pressure compensation module receives the oxygen sensor signal and the pressure signal and to perform dynamic pressure compensation. A summing module generates a compensated oxygen signal based on the static pressure compensation and the dynamic pressure compensation.
