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

      Note


      • As the front evaporator temperature sensor cannot be reused if it is removed, perform the inspection with the thermistor installed to the cooler evaporator.

      • Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.


      • When measuring the resistance, make sure the sensor temperature is almost 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 front evaporator temperature sensor.
