ROOM TEMPERATURE SENSOR(for Rear) INSPECTION

PROCEDURE


  1. INSPECT COOLER (NO. 2 ROOM TEMP. SENSOR) THERMISTOR


    1. B005N25C02
      *a

      Component without harness connected

      (Cooler (No. 2 Room Temp. Sensor) Thermistor))
      *b Resistance (kΩ)
      *c temperature (°C (°F))
      *d Allowable Range

      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 sensing portion may change the resistance value.

      • When measuring, the sensor temp. 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 (No. 2 room temp. sensor) thermistor.
