I am getting a P0401 code.

What is your question?

I am getting a P0401 code. My EGR checks out as well as the DPFE (new). No blockages in passages. Recently my fuel rail pressure damper diaphram broke and released fuel into my vacuum lines. Could the EGR vacuum solenoid be damaged due to the fuel, and therefor throw a P0401, or do you have any other suggestions?

Maybe, or one of the vacuum lines now has a hole in it due to the fuel that went through.
