A mechanic I deal with told me that there are two temp sensors that are connected with the amount of fuel that is required for vehicle to run properly. One is on drivers side of block and is easy to find. The other one he says is behind the motor. Is he correct in telling me this? If so where is it and what is the name of it so I can buy one? Thanks for your time. Saturnsw1

In 1996 and up the saturn S model cars only had one sensor that runs the temp gauge and the ecm coolant temp its located below the upper radiator screwed into the head. ALso inspect the inside of the connector if the terminals are blue or green instead of silver you will need a new connector also.
