P04F0 CODE LARGE LEAK

[SPLMAVERICK]

So I'm an original owner of a 2022 Ford Maverick 2.0 ecoboost truck. It has been a great truck untill this morning on my way to work a P04F0 popped up so I turned around and headed back home. 9nce there was light out ( I leave at 5 in the morning California) I started doing my research on the code. Looked at chaffed wire under the driver side seat( under the truck and the mesh covering) no signs of broken wires and all connections are soild both electrical and fuel. Nothing loose or anything like that. Check ylunder the hood all good. Read about evap lines rubbing towards the back driver side wheel. Found my problem the clip that separates the 2 lines has been vibrating and rubbing to the point that it destroyed bothe line causing my P04F0 code. There is no tsb and my local dealer wanted my truck over the weekend to figure it out. Not falling for that trick. Didn't want to take the risk of them having it and telling g me its other parts that are wrong at that they are not covered by warranty and having it for a week and a $1000 dollar bill for what I can fix foe 20 dollars. My truck is garage kept its whole life with no rodents. At work I park in. A concrete parking lot with no rodents either.

Point of the story is Check your ecoboost for this problem you don't even have to remove anything just kinda push to the side the covering and thro some light in there. Hope this helps any body's who has had this issue. In the last picture you will see the clip that causes all this damage.

Are you leaking gas?

 

[SPLMAVERICK]

No leaking gas its vapor return lines so I just bought some fuel lines and clamps for now. Going to see what the dealer says about covering it under warranty. Chances are I'll be replacing the lines myself. For now it works fine. I also put some tap on the electric wire because it was showing signs of wear. I don't go off roading or anything like that either. Just highway miles mostly.

No

My guess would have been rodents. Was the damage under that piece that holds the two lines apart? The gas lines AND the nearby wire...coincidence? The way the lines are shredded just doesn't look like damage from mechanical abrasion.

That underside is clean.

never saw rodents leave long strands like that. maybe someone with a knife

Did your fix clear the code?

A rubbing clamp would leave smooth marks. This is anything but smooth. Definitely rodents. Good fix though. Probably last the life of the vehicle.
