DISCHARGE TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT DISCHARGE TEMPERATURE SENSOR


    1. A003L1CC02
      *a

      Component without harness connected

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

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (SEG1) - 2 (TCHT) 10°C (50°F) 166.5 to 222.7 kΩ
      15°C (59°F) 131.8 to 174.5 kΩ
      20°C (68°F) 105.0 to 137.7 kΩ
      25°C (77°F) 84.1 to 109.4 kΩ
      30°C (86°F) 67.8 to 87.5 kΩ
      35°C (95°F) 55.0 to 70.4 kΩ
      40°C (104°F) 44.9 to 57.0 kΩ
      45°C (113°F) 36.9 to 46.4 kΩ
      50°C (122°F) 30.4 to 38.0 kΩ
      55°C (131°F) 25.2 to 31.3 kΩ
      60°C (140°F) 21.0 to 25.9 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.

      Tech Tips

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


      • If the result is not as specified, replace the discharge temperature sensor.
