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

INSPECTION





E.F.I. ENGINE COOLANT TEMPERATURE SENSOR
a. Resistance inspection.
1. Using an ohmmeter, measure the resistance between terminal 1 and 2.
Resistance:
Approx. 20°C (68°F) 2.29-2.6 kOhms
Approx. 80°C (176°F) 0.300 - 0.327 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, wipe out the sensor.
