Abstract
To compensate for possible corruption in exhaust gas recirculation control caused by fuel vapor purging, while still enabling the purging to continue, an engine intake oxygen concentration may be corrected based on a fuel canister vapor purge only during boosted conditions. Responsive to the intake oxygen concentration, exhaust gas recirculation may be adjusted.
