Lone Star Stangs | The Texas Mustang Club - View Single Post - 02 F-150 DTC p0401

**lazer96gt** · 04-20-2008, 04:22 PM

I'm helping a friend with an EGR issue on his 4.6 F-150. So far based on the TSB on the DPFE I've swapped the DPFE, Solenoid/Regulator, EGR Valve, checked the passage on the intake, the evasporator tube, and the two tubes on the evasporator that the DPFE connects to. After clearing the MIL code p0401 comes back. I need some more help. What is left to check?

BTW I have search engined the DTC and have been going in circles.
