+1 on air temperature sensor.
It's held to the inner part of the right front cowl (in the space between the inner and outer cowls) with a small self-tapping screw of the type used for plastic or sheet metal- the kind with a fairly coarse thread and a tapered point. IIRC, the head is a #1 cross point with an integrated "washer" or flange.

The bright spot for you is that reinstallation does NOT require you to go through the full tupperware removal and reinstallation process. Let's see now:
* 2 push rivets at the top, on the inside of the right side cowl (inboard of the right side hot pocket). Use your stubby cross point screw driver to push the button into the body of the fasteners so you can pull them out.
* 4 push rivets of a different style (I think Honda actually calls them "clips") down the front of the inner cowl. Pull the heads (a flat-blade screwdriver or needle nose pliers help with the grip here) and the clips will follow after you hear the "click"
* 1 machine screw right at the top front of the inner cowling panel
You may also need to pull the four clips at the bottom front of the lower / middle cowlings and then the two screws and two clips that hold the triangular engine guard in place, so that you can pull said guard to get at that inner cowling piece.
Once all that is done, screw the sensor back into place (there's an opening in the cowling for the sensor itself to stick through) then reinstall the inner cowling, engine guard, and all clips.
Sounds like a lot of work but it is really only a few minutes- maybe fifteen total even if you get into a wrestling match trying to get the upper edge of the cowl properly aligned with and seated against the mounting / connecting spot next to the hot pocket.
