I have a 2000 Contour SVT and have been getting the P0402 code. I have searched the forums but am a little bit confused. If this is the only code that I have, would the DPFE sensor need replacing? Many of the other threads concerning DPFE replacement have a P0401 code of insufficient flow rather than excessive flow like I have, or am I just mistaken?
Also where can I purchase a new DPFE sensor? The Ford dealership has it for $100, but I tried calling Autozone, Pepboys, and NAPA, all of which did not have it in stock. Do I need to ask for it be a different name at these places, or is it a dealership only part now?
