Did the scan tell you which corner it is? If it doesn't say which corner, I guess it could be an actual speed sensor on the tranny or diff, but I wouldn't think so.
The "speed sensor" is in the transmission. I know, since Subaru broke mine when they replaced my clutch, and it's popped open a few times (which puts the car into limp mode and the speedo reads 0). It's on the top/passenger side of the tranny just aft of the exhaust mount for the downpipe.

My guess is that it's probably a $100 part or so, and the install probably isn't much more then unscrewing the old one screwing in the new one.
