FRONT EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT EVAPORATOR TEMPERATURE SENSOR (NO. 1 COOLER THERMISTOR)


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

      *c Resistance (kΩ) *d Allowable Range
      *e Temperature (°C (°F)) - -
      Standard resistance
      Tester Connection 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

      If the resistance is not as specified, replace the evaporator temperature sensor (No. 1 cooler thermistor).

      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).
