Question Error Code P0401 (Replaced EGR Valve and DPFE Sensor)

After doing some routine maintenance and having flow-master put on my little pick up, the check engine light popped on. Got the codes P0401, did some research, replaced the egr valve, DPFE sensor, checked the rubber hoses (Great Condition), checked the pipe(No cracks) and could not find any buildup inside the tubes or pipe. Put everything back together, reset the computer via negative battery terminal and the light came back on within two days. I'm pissed and will take any advice given. The only other thing i can think to check is the damn wiring.

Did you check for codes since the CEL came back on?

What brand DPFE did you get?

I am going to auto-zone during my lunch hour and have it scanned again.

Unfortunately i bought the cheaper MasterPro one, i could not afford the forty dollar difference for the motorcraft.

Just got back from auto-zone, the only code that came up was P0401. I fiddled with the connection on the DPFE a little and reset the computer. Lets see how long it takes for the ENGINE LIGHT to come back on. I don't know, i think i should have paid the extra forty bucks for the motorcraft part.
