Does anybody know if a blocked off EGR valve will fail an emissions test? I will be going in next week and I have no idea what to expect.

does it throw any codes? newer j's don't have an egr valve i believe. i only have to take one vehicle ever in for emissions (others are registered in counties away from Milwaukee/Racine area), but they plug in to the obd2 and read it and thats it. by the time they have me sit down they're already done.

Ugh dammit thats what I figured. I throw the code. I do have an obd II scanner, so if I just erased the code when I got there, would it still fail if the code is pending?

i would think they would be smart enough to look at freeze frames and determine that you have a pending egr code and no egr flow.

No, all the flags in the ECM have to set for it to go though the test....

take the plate off, or get HPT.

Simple.
