      *a

      Component without harness connected

      (No. 1 Cooler Thermistor)
      *b Sensing Portion
      *c Acceptable Range
      *d Resistance (kΩ)
      *e 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
      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


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