1999 Isuzu Trooper EGR Tube

I have a 1999 Isuzu Trooper with 3.5L engine. Got a check engine light and had the code checked to find it was a P0401. Bought a new EGR valve and replaced only to have the code reappear after 30 miles. Now it seems I need to clean the EGR tube behind the throttle body. I have seen other posts saying all I need to do is open the butterfly and clean the tube with cleaner and I wire brush.

I have taken the air induct tubing off but still cannot seem to locate the tube behind the butterfly.

Any suggestions? A pic would be helpful!
