Code: P2C90 - Crankcase Ventilation System - Hose 'A' Disconnected on 2025 Explorer ST with Fen Fab V2 Intake

[BigBenTX]

I'm curious if anyone has seen this code before? I have a 2025 Explorer ST with the Fen Fab V2 Intake, CVFab Intercooler with Hot/Cold Pipes installed as well as the Big Mouth intake.
I looked and don't see any loose connectors that are causing it or anything disconnected as the code says.

I’m having the same code. Have you figured anything out?

Not yet, what modifications have you done? Seeing if we have any common mods. Are you a 2025?

do you know if those things will void the warranty? Have you tried the dealer?

I doubt you would have an issue with just those mods but it's always a risk modifying a car still under warranty.

I’ve got the same except for exhaust. I never got the code until I put the Fen Fav V2 Intake on. Then it pops it occasionally on a long extended pull from a stop to acceleration onto a freeway onramp
