The CTS is a device that monitors the coolant temperature. On the '91 and later Jeep 4.0L engine, it is mounted in the thermostat housing (see photo below). As the coolant temperature increases, the resistance of the sensor decreases, providing a varying output voltage to the ECU. The ECU uses information from the CTS to adjust air/fuel mixture, ignition timing, and to switch on the electric cooling fans.
The electric fans are programmed to switch on when the coolant temperature reaches ~105*C (~220*F) and off again when it falls back to ~95*C (~200*F). The ECU can be tricked into switching the fans on at ~100*C (~210*F) and off at ~85*C (~185*F) by splicing in a 4.0kohm resistor across the two wires going to the CTS.
