Default EGR Valve frustrations

Hello experts, do I have a problem for you! I have a 2000 Toyota Camry
LE 4cyl auto. The car has 230,000kms on the clock and other than that
stupid EGR valve, runs perfectly. I have been having this problem for
about 8 months now and I can't seem to figure it out. Neither can the

Last May, I was just getting on the highway when my check engine light
came on. Once I reached my destination, I called the dealership to
schedule an appointment to get it checked out. The car had two codes:
1 EGR insufficient and EVAP. The Evap was easy to fix: New filler neck
and no more problems.

They said the EGR problem was not current and that it was probably a
one time deal. I said ok and went on about my day. After a few days,
the light came back on. I took it back in and sure enough, P0401, EGR
insufficient. They tested the EGR valve and it seemed to be working
properly, but the VSV switch was not. I replaced it with the hope of
never seeing the light again. Well, it came back on, on my way home
from the dealer. I turned around. They wanted to take the new part out
and replace it with the old one. I said forget it and demanded my
money back.

After receiving my money, I went to an independent mechanic and he
kept the car for two days while testing the valve and stumped to see
it pass every time.

Here I am now, with a stubborn EGR valve and a more frustrating engine
light. Any help would be greatly appreciated!
