REAR EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT REAR EVAPORATOR TEMPERATURE SENSOR

    *a

    Component without harness connected

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

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      7 (-) - 8 (+) -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

      If the result is not as specified, replace the rear evaporator temperature sensor.

      Note


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

      • 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).
