Anybody know what this is on my EV1100??

That is a temperature sensor.  It can be used for ambient air temp or crankcase internal oil/air temp.  The computer needs to know this data in order to 'compute' and dictate the amount of fuel required for each propulsion cycle.  If you suspect it is faulty there are test procedures for it.

What year EV??
Since it is dry, I presume it is the ambient air temp.  Probably should be located in the frame, somewhere up near the steering head?  So, it probably doesn't matter too much where  you reinstall it.  Try to keep it away from engine  heat and in a nice aerodynamic flow of ambient cooling air.
'98EV had an identical sensor embedded in the left valve cover to measure internal air/oil temp.  But that would be oily upon removal.  Later years had a better cylinder head metal temp sensor.

Did some of the early 1100s have the temp sensor in the airbox somewhere?

IIRC My '98 V11EV put that sensor in the air path just ahead of the right side combustion air intake horn so it was monitoring what went into the air box.

Yep. Winterized my 98EV today. Pulled the tank to check the air filter and took a pic.
