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

Plenty of 2025 cars with no issues and that CAI…same goes for 20-24 cars.
It’s been proven about 99% of the time it’s an installer error somewhere along the way. Rarely has it been a part issue. Double and triple check every aspect of your install…even if it “looks” good…get hands on and make sure it IS good.
