DUCT TEMPERATURE SENSOR(w/ Heater) INSPECTION

PROCEDURE


  1. INSPECT DUCT TEMPERATURE SENSOR

    A01X19NE01
    *a Component without harness connected: (Duct Temperature Sensor)
    *b Resistance (kΩ)
    *c Maximum permissible value line
    *d Temperature

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 at 10°C (50°F) 9.4 to 10.5 kΩ
      1 - 2 at 15°C (59°F) 7.5 to 8.3 kΩ
      1 - 2 at 20°C (68°F) 6.0 to 6.5 kΩ
      1 - 2 at 25°C (77°F) 4.8 to 5.2 kΩ
      1 - 2 at 30°C (86°F) 3.8 to 4.2 kΩ
      1 - 2 at 35°C (95°F) 3.1 to 3.4 kΩ
      1 - 2 at 40°C (104°F) 2.5 to 2.8 kΩ
      1 - 2 at 45°C (113°F) 2.0 to 2.3 kΩ
      1 - 2 at 50°C (122°F) 1.6 to 2.0 kΩ
      1 - 2 at 55°C (131°F) 1.3 to 1.6 kΩ
      1 - 2 at 60°C (140°F) 1.1 to 1.4 kΩ

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

      Note


      • Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.

      • When measuring the resistance, the sensor temperature must be the same as the ambient temperature.

      Tech Tips

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