EGR Valve vacuum

[90_ACCORD]

well i mean the egr valve is good. there is nothing wrong with it. its not even a year old.

i dont know if it is actually working while i drive. no check engine light comes on or anything.

i took the hose off to test if there was a vacuum and when i reved the engine i felt no vacuum occur in the hose.

It's only gonna produce no more than 2-5 inches of vacuum so naturally, you won't feel it. Are you failing emissions? If not, don't worry about it.

yeah i failed thats the whole reason im messing with it.

the only thing it failed was the NOx. i took it to a mechanic and they said i had to much carbon build up and that was my main problem so i cleaned everything out tonight and thats when i checked for the vacuum and didnt feel any.
