The CTS is what measures the coolent temperature and kicks off the fans at HIGH speed when needed. It's not a level sensor. Might also be known as the water temp sensor. Actually, my CTS looks exactly like what the "A/C ACC Temp Sensor" looks like for your car.

Do a search on "sensor" in fastlane for your vehicle. You'll see pictures of most all of the sensors in your vehicle.
