FRONT EVAPORATOR TEMPERATURE SENSOR INSPECTION

PROCEDURE


  1. INSPECT NO. 1 COOLER THERMISTOR


    1. Disconnect the connector from the No. 1 cooler thermistor.

      *a

      Component without harness connected

      (No. 1 cooler thermistor)

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

    2. 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


      • 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).

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