This video for a Rodeo, it's basically the same procedure for a VX except that the throttle on the Rodeo is electric, and ours is mechanical, so you'll have to disconnect the bike-shifter-style mechanical throttle lines (it should be obvious looking at them, but if you need help I can take pictures). I kept cleaning the manifold EGR tube from the valve side (using carb cleaner and a trombone brush), but I could only get it in a few inches before it couldn't make the bend, this video was what I needed to get at the rest of the tube. By taking off the throttle in the front and getting at the EGR tube from the other direction, I managed to get the whole tube cleaned. Also, I managed to get at the EGR tube without disconnecting the coolant from the throttle (the tricky bit in the video where he used a couple of bolts to plug the holes). Instead, I just let the throttle assembly hang there... unbolting it and moving it out of the way gave me enough room to see the hole and what I was doing. I'm praying my P0401 code has been put at bay for a while now, I'm pretty hopeful given the gunk I saw come out of there.
One more helpful hint... I forget who mentioned this, but you can tell if your EGR tubes are clean or not by taking the EGR off and running the engine: The bigger, more rearward hole under the EGR valve should be shooting out exhaust, and the small one in the front should have enough suction to grab hold of your finger if you place it there. If either thing isn't happening, then the respective tubes need cleaning.
