CLT / CTS | Coolant Temperature Sensor


A variable resistance thermistor that changes resistance as the engine's coolant temperature changes. The sensor's output is monitored by the engine computer to regulate ignition timing, injector duty cycle and to regulate the radiator-cooling fan. Resistance goes down as heat goes up.

CLT Resistance

To check, unplug the sensor and place the Multimeter leads across the terminals of the sensor. Check for resistances below.

Temp Nominal Range
25*C(77*F) |9K-11K Ohm
100*C(212*F) |600-800 Ohm
