Abstract
A system module is provided for recirculating exhaust gases from an internal combustion engine to an intake manifold of the internal combustion engine. The module includes a body () including a passageway () between an exhaust gas inlet () and an exhaust gas outlet (). An orifice () constricts the flow of exhaust gases proximate the exhaust gas outlet. A differential pressure sensor () is constructed and arranged to sense differential pressure across the orifice. A manifold absolute pressure sensor () is constructed and arranged to sense vacuum pressure associated with the exhaust gas outlet. A first hose () is coupled with the body and provides the differential pressure sensor with vacuum pressure on a first side of the orifice. A second hose () is coupled with the body and provides the manifold pressure sensor with vacuum pressure. The first and second hoses are integral with the system module.
