IF you have a 2004-2010 5.4 L 3V engine, you do NOT have an EGR system, or ANY of it's ancillary components.
It is ALL handled via the PCM - VCT control.
If you insist on believing otherwise, I/we cannot help you.
I challenge you to find an EGR valve or DPFE device on yer 5.4 3V engine.
I WILL eat my Depends - soiled or otherwise - IF you can provide definitive proof.
Be advised - I HAVE already exhaustively surveyed my entire engine compartment and ALL relevant factory documentation regarding this and have confirmed my findings.
Be prepared to eat Caca , lol. J/K
Papa Tiger nailed it, in essence
