A buddy of mine had that same problem and ended up getting a new EGR valve and swapping out the old one ('94 pickup). Since it needed to get smogged (in CA), he could not have the CEL coming on at random.

I did that test once, and almost killed it, did it again and killed. so it can open. The fact about the carbon maybe true too. when i took it off it look pretty carboned up on the inside of the tube, but not seem out of the ordinary. i might just need to replace the egr valve. probably cheaper than the sensor.....
