Crankcase Ventilation System Disconnected Engine Code

[Busser48]

So I installed the UPR dual valve catch can, and after around 100 miles or so I got the same code. I doubled checked the pcv hose that connects to the intake and made sure it was clicked in place. The ecu was reset and all was good until about another 100 miles. I got the the same code again. Any ideas on what I should be checking?

I'm going to double check the connections when I perform a boost leak test but I'm just curious on why its happening. Thanks!

Check the tsb bulletin we were taking about in the other post you might have the old PCV system and need the updated one, gutting the PCV is not the best thing to do anymore st this point until you update to the new parts and computer update.

This is a common (P04DB) code. It just needs to be disabled by your tuner. When you gut your PCV and add a catch can you are lowering the amount of flow the passenger side crank case sensor sees. It goes below the threshold and throws a code. Disable it and you are good to go.

Mine and a bunch others got the code on and off after an intake install, prior to any catch can install.
