PO4DB code w banks ram air

As title states I've had the banks ram air on the truck for 10K miles, yesterday I popped the crank case ventilation disconnected.....which was not true dealer was attributing the code to the banks CAI? Any thoughts?

Does the CAI have a crankcase hose installed on it? If yes it may very well be the CAI.

Check connections at red arrows.

Thanks for the info, I ended up calling banks to see if they had heard of the code popping and they had. They reengineered the intake tube at some point to fix the problem and I had the old version so we'll see how it works out as they are currently shipping out the new version. Great customer service as always from Banks Power!

So it obviously flows different than the stock system and is fooling the crankcase pressure sensor.

Stick with stock intake and air filter and enjoy!
