ROOM TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)


    1. Check the resistance.


      1. A005Q29C01
        *a

        Component without harness connected

        (Cooler Thermistor (Room Temperature Sensor))
        *b Sensing Portion
        *c Resistance (kΩ)
        *d Temperature (°C (°F))
        *e Allowable Range

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 10°C (50°F) 3.00 to 3.73 kΩ
        15°C (59°F) 2.45 to 2.88 kΩ
        20°C (68°F) 1.95 to 2.30 kΩ
        25°C (77°F) 1.60 to 1.80 kΩ
        30°C (86°F) 1.28 to 1.47 kΩ
        35°C (95°F) 1.00 to 1.22 kΩ
        40°C (104°F) 0.80 to 1.00 kΩ
        45°C (113°F) 0.65 to 0.85 kΩ
        50°C (122°F) 0.50 to 0.70 kΩ
        55°C (131°F) 0.44 to 0.60 kΩ
        60°C (140°F) 0.36 to 0.50 kΩ

        Note


        • Hold the cooler thermistor (room temperature sensor) only by its connector. Touching the sensing portion may change the resistancevalue.

        • When measuring, the cooler thermistor (room temperature sensor) temperature must be the same as the ambient temperature.

        Tech Tips

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

        If the result is not as specified, replace the cooler thermistor (room temperature sensor).
