To be absolutely certain, you should:
* Consult your vehicle's repair manual: This will have a diagram showing the exact location of the EGR valve.
* Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) have diagrams you can search by your vehicle's year, make, and model. Search for "EGR valve" within the diagram.
Visually searching for a small valve with vacuum lines connected to it in that general area should help you locate it once you have a visual reference.
