Starting last month I had the ecm scanned and it showed 3 codes P0400, P0401, and P0402 so I replaced the DPFE sensor and the next day the Service engine soon Light went out O. K. great it solved the problem!! Wrong roughly 3 weeks later the light came back on and threw Code P1400 also after erasing this code it threw codes P0401 P0402 again but not P0400 witch was DPFE Fault!!! also with my actron scanner its telling me that P1400 witch I beleive to be Ford Specific says Manufacturer Auxillary emissions system and I have no idea what this system consists of the other two codes where EGR Excessive flow also other code was Insufficient flow I tried removing EGR valve and cleaning it out along with the intake port and exhaust tube no improvement as far as codes go its still showing all three engine other than slightly rough idle and almost stalling on occasion when letting off of the gas at a stop light runs great and has no lack of power!! I also checked exhaust flow through EGR tube to valve and seemed unrestricted!!! any and all Info would be greatly appreciated Thank you in advance!!!!
