2000 accord ULEV
Now before we get in to this, I know what the P0401 is and I know that the EGR valve is ok. I Ohm'd the EGR valve and got 1.7k ohms from pins 1 & 2 and 3.7k ohms from 1 & 3. The snap-on scanner said that if it was over 100k ohms suspect the EGR valve but since those numbers seem to be ok I figured the passages need a good cleaning. I have read some of the other threads and i'm aware that you need to take the intake off to do the cleaning correctly. I have also seen that you need to drill and tap in tubes in the clogged passages. Im wondering if anyone has performed this and what procedures where used and what you used as tubes to tap in... thanks for the advise!
