There "is" a chance that a wire that is rubbed-through and grounding out "can" blow this fuse. The EFI fuse covers a few different things (click here for an image) including "engine controls", of which, the Oxygen Sensor would be in that system. It "is" possible that the wire only grounds out while the vehicle is in motion and the body moves to contact the wire. HOWEVER, as you can see in the image I sent, this fuse also covers items in the Transmission Systems and the Engine Immobilizer (part of the anti-theft system) as well. So if you find the problem only happens while driving, there's a chance the problem lies in a transmission-related area. Might be a good idea to have a second opinion, and preferably from a shop that has experience in automotive electrical systems as opposed to a general shop.
