FRONT EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 1 COOLER THERMISTOR


    1. B004THHC04
      *a

      Component without harness connected

      (No. 1 Cooler Thermistor)
      *b Sensing Portion
      *c Resistance (kΩ)
      *d Temperature (°C (°F))

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 -10°C (14°F) 7.30 to 9.10 kΩ
      -5°C (23°F) 5.65 to 6.95 kΩ
      0°C (32°F) 4.40 to 5.35 kΩ
      5°C (41°F) 3.40 to 4.15 kΩ
      10°C (50°F) 2.70 to 3.25 kΩ
      15°C (59°F) 2.14 to 2.58 kΩ
      20°C (68°F) 1.71 to 2.05 kΩ
      25°C (77°F) 1.38 to 1.64 kΩ
      30°C (86°F) 1.11 to 1.32 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, there may be a malfunction in the No. 1 cooler thermistor.
