Engine Bay Fuse number 12

[Catlicker1989]

Hi,

im new here and purchased a 22 bronco sport big bend 1.5 to fix up! I was wondering if someone had a diagram on everything that’s powered by Fuse 12 in the engine bay fuse box. Looks like there is a dead short either by a sheared wire or a bad component. Before I start going thru the harness the hard way I figured I’d start here! I’m also looking for the wiring diagrams for the boost control solenoid, the oil pressure solenoid and the evap systems but fuse 12 is my main concern at the moment

thank you and happy holidays!

no warranty so there’s nothing I can void!

Trust me you are going to have to do it the hard way..... a dead short popping the fuse is going to be noticeable. The distance between the ECU and a fuse box isn't far. I rebuilt a 2005 Mustang and did a v6 to v8 swap. The most valuable thing I purchased that helped me during the project was the factory wiring diagram book from Ford. If your rebuilding a Bronco Sport GET THAT BOOK right now!

Yeah I seen that in the owners manual, I currently have a few codes related to mostly evap and was thinking it’s partly something to do with the that system.

Unfortunately that’s probably the case. It’s a salvage car, and just tring to keep the cost low and the downtime to the minimum. I just don’t feel like going through the harness and finding out it was a short in one of the sensors or connectors haha. Plus it’s easier to sort through the harness in sections that may have the issue and not mess with the rest.

Replaced a bunch of stuff so far and everything has been working good in my favor. Could have been an electrical grimlin that caused the accident the way it’s looking.

If you still have the vehicle I suggest you pull the connectors to the ECU module(s) located under felt at drivers front fender - there’s the ECU located there and a module on the other side with at least one connector - if these 2+ connectors show signs of water intrusion - that has been a reported cause of the blown fuse and / or wiring short (I don’t know however if it was F12)

Oh without a doubt. It's highly probable the damage to the harness is in the location of the wreck. Keep it simple at first. Look for places that the loom to the wire harness was pinched or smashed. This a a dead short and until you find the damage and repair it don't keep putting fuses in it, you don't want to send voltage through a wire that can cause damage to a component or module. And whatever you do don't put a larger fuse than whats called for in that location. That will definitely cook something.

LOL, I currently have 4 cats in my household. I found this avatar about 20 years ago and I have been using it ever since. I have no clue who Luis Beretta is.

Exactly. I took the car for a drive after replacing the endlinks, steering column, tierod ends and inner tie rods. Replaced passenger wheel and liner. Drives nice overall and everything seems to function. Seen that a few codes were for the evap. Removed the undercover driverside and the canister and lines / wires looked alright from a quick inspection. So I opened up the fuse box and found that fuse had no continuity so I knew it was dead before I even pulled it.

I have the diagram from a 2022 escape with the 1.5 so I know it’s not the same. But I used it to kind of see if 2 of the solenoids that codes come up with are on the same circuit just for the heck of it and they are.
