        *a

        Component without harness connected

        (Engine Coolant Temperature Sensor)

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 Approximately 20°C (68°F) 2.32 to 2.59 kΩ
        Approximately 80°C (176°F) 0.310 to 0.326 kΩ

        CAUTION:


        • Do not put your hands into the water that has been heated for the inspection.

        • Touching the heated water could result in burns.

        Note


        • When checking the engine coolant temperature sensor in water, keep the terminals dry.

        • After the check, wipe the engine coolant temperature sensor dry.

        If the result is not as specified, replace the engine coolant temperature sensor.
