    AFE Intake 2017 EcoDiesel throwing P04DB

    Never thrown this code. Owned my truck for 6 weeks. Constantly checking codes to see if anything is wrong, and has not thrown codes yet. Relatively new to the ECO Diesel 3.0. Put an AFE full intake on it with open box and filter. Only sensor I had to unplug was the MAF, so I could bolt it to the new AFE Lid. Drove about 5 miles right after install to see if had any codes, and nothing. Today I went and drove 40 Miles, and when I got home, threw my scanner on it just to double check if there was anything lying in wait, and sure enough P04DB was there. This intake replaces the upper lid, with AFE open lid, and hard pipe to oval connection just on top of the turbo...

    Any thoughts or suggestions?

    Curious, on the situation now that I thought about it, but with every other vehicle I have ever added a cold air intake or hard pipe, I have always gone in and scaled the MAF.... Thoughts on if this might fix the issue?
