Hey guys I am dealing with the 0411 code, and I have checked everything out. Everything actually checks out fine, so I am circling back to make sure the components are actually good.

I tested the EGR valve, and it is closed without vacuum applied. When I apply vacuum (>20 in Hg) the valve opens and you are able to blow through it. This being said, the amount of flow is small, which makes me concerned that this could be my problem.

Has anybody encountered this issue, or tested a new EGR valve to know what is typical?

 

its possible for the valve to be clogged so cleaning it out with brake clean is an option but the main reason to clean it is to get the carbon out so the valve doesn't intermittently stick... also make sure the vacuum doesn't bleed off

 

I did clean the EGR while I had it out, I didn't have any brake or carburetor cleaner so I'm sure that I could clean it out better if I did it again. My concern is that it is not opening as wide or as easily as it was designed. Other forums and posts concerning EGR's say that it should open under low vacuum.

Mine would not open under low vacuum. However it does hold vacuum fine. I am also planning to do the test where you apply vacuum to the EGR at idle, to see if it chokes the car out and dies. I also have another EGR on order, so I will update you guys when I find out more.
