Front of intake mani there are two sensors. One on right as you view the pic is a coolant temp sensor for the emissions system. What is the other one. It appears to be a coolant temp sensor also but I can't find it in the FSM or the Chilton. Thanks.

 

Could it possibly be for the temperature gauge reading?

 

That's what I'm thinking. I can't find a sensor for the instrument panel anywhere else. I'd feel better if I knew for sure.
