General Information

TOC

The EGR valve differential pressure sensor has two ports that sense a pressure drop across the EGR gas entrance to the intake connection. The ECM uses this pressure drop to calculate the amount of EGR gas entering the intake. This calculation helps to determine the commanded position of the EGR valve (and VG turbocharger) that will control the amount of EGR gas flow into the engine.

The EGR valve differential pressure sensor is mounted on the side of the intake air horn.
