Hi Folks, I have a '99 Contour SE with a 2.5 liter Duratec and auto transmission. I was getting an EGR insufficent flow(p401) code. We replaced the EGR valve, the vacuum regulator solenoid and the pressure feedback sensor. The code is now a "P1408-EGR Flow out of Self-Test Range" Any ideas? Thanks in advance.



If the cleaning does not fix it try the hoses that lead to the DPFE sensor. the parts guy told me those hoses can become brittle and clog. I have seen this code on a 2001 windstar and my 2001 explorer and both were just a matter of replacing the DPFE sensor. my truck has 135,000 miles and the windstar has 113,000 miles. Both same code. Ford told me they replace these parts all day long.
