EGR Valve: Description and Operation
ENGINE CONTROL COMPONENTSElectric Exhaust Recirculation Valve (EEGR) Valve
The EEGR valve is a water-cooled motor/valve assembly. The motor is commanded to move in 52 discrete steps as it acts directly on the EEGR valve. The position of the valve determines the rate of EGR. The built-in spring works to close the valve against the motor opening force.
