COOLER THERMISTOR INSPECTION

PROCEDURE


  1. INSPECT COOLER THERMISTOR

    A005JJQE01

    1. Check the resistance.


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

        Text in Illustration
        *a Maximum permissible value line
        *b Minimum permissible value line
        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 10°C (50°F) 9.4 to 10.5 kΩ
        1 - 2 15°C (59°F) 7.5 to 8.3 kΩ
        1 - 2 20°C (68°F) 6.0 to 6.5 kΩ
        1 - 2 25°C (77°F) 4.8 to 5.2 kΩ
        1 - 2 30°C (86°F) 3.8 to 4.2 kΩ
        1 - 2 35°C (95°F) 3.1 to 3.4 kΩ
        1 - 2 40°C (104°F) 2.5 to 2.8 kΩ
        1 - 2 45°C (113°F) 2.0 to 2.3 kΩ
        1 - 2 50°C (122°F) 1.6 to 2.0 kΩ
        1 - 2 55°C (131°F) 1.3 to 1.6 kΩ
        1 - 2 60°C (140°F) 1.1 to 1.4 kΩ

        Note


        • Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.

        • When measuring the resistance, the sensor temperature must be the same as the ambient temperature.

        Tech Tips

        As the temperature increases, the resistance decreases (see the graph).

        If the resistance value is not as specified, replace the sensor.
