The EGR (Exhaust Gas Recirculation) valve opens when vacuum is applied. The EGR vacuum solenoid opens and closes the vacuum supply to the EGR valve when it is commanded to do so by the ECM (Engine Control Module).
an egr valve opens to put inert gases in the combustion chamber to lower the temperature. this is done to reduce NOx emissions that are produced at high temperatures.
There won't be any vacuum to the egr while idling. Engine must be warmed up and under acceleration or cruising before vacuum opens egr valve.

Its inside the egr valve whether digital or conventional, its basically the door that opens up for emmissions and no2 mixtures.
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
It may be a EGR valve issue. This valve is normally closed at idle and opens at about 40mph.
Yes, the EGR valve, or port EGR
There is only one EGR valve on your truck. This is the one you should clean because it is attached to the exaust manifold and is likely to have carbon build up. The other part EGRSOL is a EGR solnoid (valve) that opens at the proper time to allow vacuum to open the EGR valve.
I believe the DPFE is called a Differential Pressure Feedback EGR sensor It has something to do with controlling the amount the EGR valve opens ( P.S. I'm not a mechanic / technician )
It doesn't have an egr valve.
As I recall, that engine does not have an EGR valve.
