I recently had a Ducati Performance air filter and the Termignoni cans put on. My shop sent my ECU out for a reflash and when it came back, a new indicator was available as one of the view options in the cluster (in addition to the time, trip, odo, etc).
"T. Air"
I assumed it was some sort of air temperature and Google only shows a link on the other Ducati forum saying it's the ambient air temp. Makes sense, however mine starts low when you start riding but keeps going up slowly until it's around the 118-120 mark. On hot days, once it passes 123F, it goes to "---F" like it's maxed out or something. This initially led me to believe it was intake temp? Not sure.
What is it exactly? I was going to call my Ducati shop, but they're not open yet.
1st guess, ambient air temp sensor as well.
Is the air temp sensor where it should be? I'm wondering if it got moved and is now dangling near the head and reading elevated temps as a result
It's possible. Strange that this just popped up though. 25K miles of riding and I never see this indicator before.
The ambient temperature sensor is located in the V and measures intake air temprature which is pretty darn warm.

Should I be worried that it's going above what's numerically indicated? It goes to "---F" after 123F. I know it's not VERY high, since it goes down to 120F after I start moving again.

No. The temperature sensor is there to tell the computer what the intake air temperature is so fueling can be appropriately corrected.
Since you never saw this indication before, and now do, you might consider inspecting the sensor harness, connector, and sensor housing integrity in case it is an intermittent condition. I believe it is located on the vertical intake.
Since the lack of the air temperature display was not a concern previously, and since you were surprised when it did appear, would that mean that you do not have an owner manual.....or?

Yes, I will take a look this weekend, thanks.
I do have an owners manual, and I admit I was being lazy, but:
* I'm at work. Manual is at home.
* Manual is still wrapped nicely and binded in plastic like from the dealer. Didn't want to remove it. :P
So he never saw this indicator before he had the ecu reflashed. The first 25k is irrelevant.
I remember reading about the first new Monster years having this info, but it was misleading so they took it off the instrument display.
... and/or changed the sensor position... or something like that..

AFAIK, no read out on 796 or 1100, remains on 696. Not positive though.

There is a read out on the +2012 1100 Evo.
+1 2009 1100S Got it but not on the DP ECU only on the Std and Remapped (Rexxer ECU)???
Pretty sure my 2013 696 has it when I flip to it. Per the 696 manual:
Air temperature indicator
Shows the outside air temperature.
Display limits: -39°C ÷ +124°C.
In the event of a sensor FAULT (-40°C,+125°C or
disconnected), a string of dashes "- - -" (not flashing)
is displayed and the "Vehicle/Engine diagnosis -
EOBD" light comes on (8,Fig. 8) .

True dat on 1100 Evo. Don't know why they don't display it on the DP tune.......oh yeah, I do. [evil]

Interesting. I don't have a CEL though. Weird. I'm going to call the shop and see.
Update...
Appears to be a faulty air temp sensor. Took it to my shop and the guy will replace it for me and see what happens. He happened to have that part on hand. He was initially worried that these bikes were similar to the newer ones with combo pressure/air temp sensors (that would be more pricey). And he was actually surprised that my 2012 had a separate one since this part failed somewhat often.
I'll update when I have more news.
