EGR Control Solenoid: Description and Operation
Exhaust Gas Recirculation (EGR) Valve - Description
DESCRIPTION
The Hybrid Electric Vehicle (HEV) uses a High Flow EGR valve. The High Flow EGR valve can only be used on the HEV engine and is not compatible
with any other engine applications. The High Flow EGR valve consists of three components. First, there is the pintle, valve seat, and housing which
contains and regulates the gas flow. Second, there is the armature, return spring, and solenoid coil to provide the operating force to regulate the flow by
changing the pintle position. The solenoid coil assembly is in parallel with a diode and connects the two connectors in the connector assembly. Third,
there is the pintle position sensor which senses pintle position and is connected to the three connectors in the electrical connector assembly.
