Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection

INSPECT ENGINE COOLANT TEMPERATURE SENSOR




a. Resistance inspection.
1. Using an Ohmmeter, measure the resistance between terminals.

Resistance:
2.32 - 2.59 Ohm at 20 °C (68 °F)
0.310 - 0.326 Ohm at 80 °C (176 °F)

NOTE: When inspecting the water temperature sensor in water, prevent water flow into the terminals. After inspection, wipe the water off from the sensor.
