      *a

      Component without harness connected

      (Evaporator Temperature Sensor (No. 1 Cooler Thermistor))
      *b Sensing Portion
      *c Resistance (kΩ)
      *d Allowable Range
      *e Temperature (°C (°F))

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      a1-1 - a1-2 -10°C (14°F) 7.30 to 9.10 kΩ
      a1-1 - a1-2 -5°C (23°F) 5.65 to 6.95 kΩ
      a1-1 - a1-2 0°C (32°F) 4.40 to 5.35 kΩ
      a1-1 - a1-2 5°C (41°F) 3.40 to 4.15 kΩ
      a1-1 - a1-2 10°C (50°F) 2.70 to 3.25 kΩ
      a1-1 - a1-2 15°C (59°F) 2.14 to 2.58 kΩ
      a1-1 - a1-2 20°C (68°F) 1.71 to 2.05 kΩ
      a1-1 - a1-2 25°C (77°F) 1.38 to 1.64 kΩ
      a1-1 - a1-2 30°C (86°F) 1.11 to 1.32 kΩ

      Note


      • Hold the sensor only 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 resistance is not as specified, replace the evaporator temperature sensor (No. 1 cooler thermistor).
