Abstract
Systems are provided for EGR mass and air mass estimation during steady state and transient operations. By utilizing a combination sensor comprising of a manifold absolute pressure sensing element and a differential pressure sensing element sharing a common pressure chamber with connections to the intake manifold, errors in EGR mass estimation may be reduced.
