    The CTS is usually located in the lower intake somewhat close to the thermostat. Since the coolant temp is usually the same or higher then then temp of the lower intake the sensor is fairly accurate. on most body platforms there is seperate CTS sensor that runs the dash coolant temp guage.

    The sensor is a thermosistor, as the coolant temp gets higher the resistance drops. The ECM supplies the sensor +5V and measures the voltage drop through the thermosistor to determine temperature. Some resistance vs temperature values follow:

    *F--------Ohms
    210----------177
    158----------467
    104----------1459
    68------------3520
    32------------9420
    -4-------------28680
    -40-----------100,700

    The sensor is used for open/closed loop operation and is used in the calculation for fuel and ignition.
