    CAUTION:
    1. Do not put your hands in the water warmed up during the inspection.
    2. Touching the hot water may result in burns.
    NOTICE:
    When checking the engine coolant temperature sensor in water, do not allow water to contact the terminals. After completing the check, dry the engine coolant temperature sensor.
    If the result is not as specified, replace the engine coolant temperature sensor.
