The round end of the sensor, where the thermistor is, sticks out the front of the grill, exactly where the water would spray.It was a brand new car wash and the water was very forceful I wonder if some water kind of got behind the grill and cooled down the sensor? Thanks for the pic!
The reading on the center screen is also a damped average, over some length of time, to avoid rapid swings in the reading you see. In Torque Pro, you can see that reading,and several undampended readings too. In reality, the air temperature at the front of the car can swing all over. If you've ever ridden a bike, you know the air temperature swings from hill to gully, over a creek, etc.
