P04DB Code on 2017 f150 3.5L Ecoboost

Post by fosterfreez » Sat Aug 18, 2018 5:41 pm

Hello All,

New here to the forum. i have a 2017 f150 platinum 3.5L ecoboost. I have added 3 mods.
1. S&B CAI
2. UPR Dual catch can
3. MBRP exhaust

Ive had all 3 mods on for over 1,500 miles and i just started throwing a code : p04DB - Crankcase ventilation system disconnected.
I have checked all connections and everything and I cannot find anything!

Can anyone please help?

Re, UPR Dual catch can

Is / was that system installed correctly ??

*** After weeks of trouble shooting the situation it turned it to be my cold air intake that was popping the code. AEM sent me out a 6 inch aluminum tube that gets inserted into one of the hoses for the air intake. (Which came with instructions). Took literally 10 minutes. I reset the code and never had a problem again.
