Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
ENGINE COOLANT TEMPERATURE SENSORINSPECTION
1. INSPECT E.F.I. ENGINE COOLANT TEMPERATURE SENSOR
a. Resistance inspection.
1. Using an ohmmeter, measure the resistance between each terminals.
Resistance:
Approx. 20 degree C (68 degree F):
2.32 to 2.59 KOhms
Approx. 80 degree C (176 degree F):
0.310 to 0.326 KOhms
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, dry the sensor.
