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

INSPECTION




1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR
a. Check the resistance.

1. Using an ohmmeter, measure the resistance between the terminals.

Resistance:
20 °C (68 °F): 2.32 to 2.59 kohms
80 °C (176 °F): 0.310 to 0.326 kohms

NOTE: If inspecting the water temperature sensor in water, prevent water from flowing into the terminals. After inspection, wipe the water off the sensor.
