Hey all just thought I would let you know, I had my check engine light come on so I took it into my brother In law(mechanic), He scanned it and it came up egr valve, checked some online program and it turns out there is a flash out for the EGR to expand its parameters(or something like that...lol). Any way took it into the dealer and they flashed it, no problems since. If you get an EGR code, most good scanners will moniter it and if the valve is working then it might just need the flash.....

 

I've got a 2007 Aspen with the 5.7L. Saw the post on the location of the PCV but must be blind or not looking hard enough around the back of the intake manifold, does anyone have a picture of the location?
Also looking for the location of the EGR. Got a PO406 code the other day. Cleared it with my code reader but have read that cleaning or replacing the EGR is the thing to do. A picture of the location would be great as well as anyone else's experience with these two items.
Thanks.
