FRONT EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE

  1. INSPECT NO. 1 COOLER THERMISTOR

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

      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:

      • 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.

      Tip:

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

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