Excessive EGR code

After six months, I finally solved my check engine light problem. It went on all of a sudden and stayed on. So, I went to my college and hooked to up to a scan tool and came up with codes for: Execessive EGR, Bank 1 running lean and Ctrl runner Stuck open. I did a pinpiont test and found out that the problem was the EGR pressure feedback sensor. I repalced it this afternoon and havent had a problem yet.
