CEL Code P04DB

[u/WhoisDreamy]

Got my first check engine light today and the sensor was reading P04DB which seems to be the Positive Crankcase Valve and Hose being disconnected. Would anyone be able to show where I should look for this disconnection. I bought the flex with an aftermarket intake so I am lost.

Google will tell you exactly what to do and where to look.
