BATTERY THERMOMETER SENSOR INSPECTION

PROCEDURE


  1. INSPECT THERMISTOR ASSEMBLY


    1. A01MJ01C19
      *a

      Component without harness connected

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

      Check the resistance.


      1. Measure the resistance according to the value(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 sensor only by its connector. Touching the sensor may change the resistance value.

        • When measuring, 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 result is not as specified, replace the thermistor assembly.
