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

COMPONENTS INSPECTION







E.F.I. ENGINE COOLANT TEMPERATURE SENSOR

Resistance inspection.
Using an ohmmeter, measure the resistance between each terminal.

Resistance:
At 20 °C (68 °F)........................2.32 - 2.59 Kohm
At 80 °C (176 °F)......................0.310 - 0.326 Kohm

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