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