ROOM TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)


    1. A01MFW3C34
      *a

      Component without harness connected

      (cooler thermistor (room temperature sensor))
      *b Sensing Portion
      *c Resistance (kΩ)
      *d Temperature (°C (°F))

      Check the resistance.


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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        1 - 2 10°C 3.00 to 3.73 kΩ
        15°C 2.45 to 2.88 kΩ
        20°C 1.95 to 2.30 kΩ
        25°C 1.60 to 1.80 kΩ
        30°C 1.28 to 1.47 kΩ
        35°C 1.00 to 1.22 kΩ
        40°C 0.80 to 1.00 kΩ
        45°C 0.65 to 0.85 kΩ
        50°C 0.50 to 0.70 kΩ
        55°C 0.44 to 0.60 kΩ
        60°C 0.36 to 0.50 kΩ

        Note


        • Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.

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

        Tech Tips

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