ABSTRACT:
A method of altitude compensation of exhaust gas recirculation in an intake manifold for an internal combustion engine includes the steps of calculating vacuum at sea level, calculating vacuum at present altitude of the engine, determining whether the calculated vacuum at sea level is equal to the calculated vacuum at present altitude, and correcting the exhaust gas recirculation in the intake manifold if the calculated vacuum at sea level does not equal the calculated vacuum at present altitude.
