EGR Control Solenoid: Description and Operation

PURPOSE
The Exhaust Gas Recirculation (EGR) Control Solenoid Valve, located at left front strut tower, regulates vacuum to the EGR valve and is controlled by the Programmed Fuel Injection Electronic Control Module (PGM-FI ECM).

OPERATION
Upon receiving electrical signals from the PGM-FI ECM, the EGR Control Solenoid Valve sends a variable vacuum signal to the EGR valve. This opens the EGR Valve a specific amount allowing exhaust gas to flow through the EGR valve.
