I know JTIS says cover must be removed, but it would be nice if that could be avoided. Has anyone done this?

Have a look at the above.

 

It's not that hard to get the cover off. Well, the front at least, I haven't had the back off yet but it shouldn't be too hard.

 

I replaced one of my rear sensors pretty easily. Didn't need to remove the whole bumper, I just undid all the fasteners on the back of it, and the one side I needed off. Pulled it back far enough to reach in there and get the job done. In my case it was an outside sensor, but I imagine one of the inner sensors would be about the same. Removing the whole bumper isn't that much more work so really IMHO you can do it either way.

 

I accessed my RR sensor by removing the tail light assembly. You can't see it from above directly but with a mirror I believe you can. I found my "bad" sensor was merely disconnected so I still have a spare I purchased on eBay in not quite the same color. Folks say the rear bumper cover is not that hard, but I bet removing the tail light is easier, and checking and re-seating the lamps in mine eliminated a code I was getting for the RR stop lamp.

 

Ah yes I forgot to mention I had to take out my left tail light to get better access to the sensor. Bumper still attached on the right side of the car.
