Gina,

To the best of my knowledge (meaning my Bently is not here in front of me),
Temp. sensor #1 is in the airbox and measures the air temp entering the
airbox, and Temp. sensor #2 is in the thermostat housing, and measures the
water temp.

I'm sure that if I am wrong someone will correct me, but I do believe this is
correct.
