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

INSPECTION

INSPECT ENGINE COOLANT TEMPERATURE SENSOR




Resistance inspection.

Using an ohmmeter, measure the resistance between each terminal.

Resistance:
2.29 to 2.60 kOhms at 20°C (68°F)
0.301 to 0.327 kOhms at 80°C (176°F)

NOTE: In case of checking the engine coolant temperature sensor in water, be careful not to allow water to go into the terminals, and after checking, dry the sensor.
