REAR EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 2 AIR CONDITIONING HARNESS ASSEMBLY (REAR EVAPORATOR TEMPERATURE SENSOR)


    1. A01IIHRC02
      *a

      Component without harness connected

      (No. 2 Air Conditioning Harness Assembly (Rear Evaporator Temperature Sensor))
      *b Sensing Portion
      *c Resistance (kΩ)
      *d 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
      -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 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 result is not as specified, replace the No. 2 air conditioning harness assembly (rear evaporator temperature sensor).
