Ambient Air Temperature Sensor

Hi All:

On Saturday I was out for a ride. There was a wee rain shower of not overly hard intensity and I went through some standing water on the road. Before the rain the ambient air temperature was 8C. Just afterwards and after a few puddles the temperature displayed was 1C. It was definitely NOT 1C. Within 3 minutes or theres about the I saw the temperature change from 1C to 8C. Just lucky on that one.

Soooo .... where is the ambient air temperature sensor located on the bike? Would water on the sensor cause it misread? Or could water seeping into a electrical connection or the sensor itself to cause it to misread?

When I took the front fairing off to fit an oil cooler guard there was a wire attached to a sensor within the fairing - I assumed that was the temperature sensor.

Great thanks for that ... going to the parts catalogue .. in the picture below it is part number 21.

Now the question still stands. Does water on the sensor make it misread? Anyone else observe this?

Don't know for sure but water falling as rain from a significant altitude is likely to be at a lower temperature than ambient air temperature so it would seem logical that if it gets on the sensor it would read lower.

I always thought the air sensor was in the airbox and was more important for the ECU and injection system. The dashboard display is just a by-product. There is another air temperature sensor in the airbox but why the bike needs two 
I've been through some pretty horrific downpours on the bike and don't recall seeing a big temperature change. Usually the temperature reading goes the other way (higher) if it's left standing - like filling up with fuel or such.
