Question about 2001 Mercury Sable
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!!! I had the same thing. The car felt out of gear and would not go. I took it to Don Davis Auto Group service department. They said I needed a new transmission. They fixed my transmission and charged me $2000. 00. The check engine light still comes on and the car still has the same symptoms as at the beginning. I have taken it back 3 times and they cannnot duplicate it. I drove it straight there when it had a real bad episode. The service manager put it on the computer and 8 codes appeared. I don't know what they were, however. I am still having the same trouble. I feel that I was charged with a transmission when I didnot need one. Any suggestions?

In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
