AMBIENT AIR TEMPERATURE SENSOR
The ambient air temperature sensor is used to detect the ambient temperature. It is always possible to detect an accurate temperature under the severe use as the thermistor element is protected with plastic case.
I would have to say it wouldn't hurt if you moved it some where in the general area. So that it would still be getting close to accurate readings of the intake air temp.
I started to wonder the exact same thing when I read that explanation. Since it is enclosed in plastic I don't think water would be an issue at all and worth a shot. Thanks for the idea, gonna try it this weekend.
