P04DB Code

[Tracked]

I just installed the Fenfab v2 intake and charge pipe with HKS BOV. My car threw a P04DB code on the 3rd drive cycle. I'm sure I installed the intake lines correctly, but what might cause this?

This connector appears to be unseated.

Good eye. That doesn't appear to be fully seated.

Great eye Wafer! Tracked let us know if that fixes it…

I just went out and re-inserted that connector and it appears to only go in that far before clicking on.

Could something with my evap purge valve be wrong with the intake and/or vacuum line install?

Was that sensor originally closer to the 90° fitting as in this picture?

Your code is a Crankcase Ventilation System Disconnected warning, I've read the sensor also has a hall effect pickup that detects when the Vent hose is moved.

Yeah it was definitely facing in that direction and is no longer. Maybe I need to trim my hose so that it can be repositioned that way as the hose is too long to allow it to go back to that direction?

Yes try to reposition it to face to same direction and at the approximate distance from the fitting, hopefully it will clear the trouble code.

How did this end up? I have the same code....

It went away after ZFG updated my tune. Popped up again maybe 18 months later, I cleared the code, and hasn't popped again in the months since.

Thank you for the response. I took my vehicle into the Ford garage and they found a loose hose leading to my air intake. They only charged me an hour labor and all is good now. So glad it was that instead of something more serious.
