Inspection [12/2019 - ]: Procedure

  1. INSPECT NO. 1 COOLER THERMISTOR 
    1. Measure the resistance according to the value(s) in the table below.

      *a Component without harness connected
      (No. 1 Cooler Thermistor)      		 *b Sensing Portion
      *c Resistance (kΩ) *d Temperature (°C (°F))
      *e Allowable Range - -

      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 sensing portion may change the resistance value.
      • When measuring, the sensor temperature must be the same as the ambient temperature.

      HINT: 

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

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