FRONT EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 1 COOLER THERMISTOR


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

      A005HEQE01
      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

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

      Note


      • Touching the sensor even slightly may change the resistance value. Hold the sensor connector.

      • When measuring the resistance, the temperature of the sensor and the cooler thermistor must be the same.

      Tech Tips

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


      • If the result is not as specified, replace the No. 1 cooler thermistor.
