Default engine sensor fuse question

If you blow an engine sensor fuse, will the car still run? or will it run poorly? will it always set off a SEL?

Yes it will give you an SES code. The car will run but basically be in a "limp" mode because I'm pretty sure that fuse powers the MAF and all four 02's. You have any idea what's causing it to blow?

i had this exact problem on my car, and yes it will light the ses light b/c the maf, o2's and a couple other things are on that circuit i'm willing to bet one of your o2 sensor wires burned on the header or is rubbing somewhere thats what mine was anyways.
