INSPECTION

1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR






(a) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance:





If the result is not as specified, replace the sensor.
NOTE: In case of checking the water temperature sensor in the water, do not allow water to go into the terminals. After checking, dry the sensor.
