I went to AutoZone this morning and they read my CEL code. It was PO401 and the definition was too little flow on the EGR system and follows;
1. Blocked passage on EGR system.
2. Failed EGR valve.
3. Failed EGR pressure sensor where applicable.
4. " " position " " " ......
Has anyone run into this problem, ( the car runs great and MPG are great ),and if so , any suggestions ? Has anyone used Seafoam in the intake and would this possibly take care of this problem.
thanx for any help,
