I have a 2001 Sable V-6 (69,000 miles) with a check engine light and had a friend run a diagnostic on it. It came back with 2 codes PO401 & PO402, which is an EGR flow code. My buddy said he checked and reset the codes and $65 and about 5 hrs. later the check engine light is back on. Any suggestions on this. Should I just go for a new valve ($$$$) or is there a sensor or vacum leak????? If this has a common fix let me know or should I take it back into the shop??? If it is an easy fix I'd like to try it myself!!!
