Question about 2002 Ford Windstar Cargo
Has anyone had this code PO402 (excess flow egr ) come up and had luck by replacing a part or did you have to go through this process of elimination of replacing everything in the Emissions system just to find it...dont have alot of cash" is it usually the EGR valve itself bad??????????its on a 2002 windstar w. a 3.8
I know this is a old post, but I had the same problem and it was the dpfe sensor. The EGR is almost never the problem with this code
