      *a

      Component without harness connected

      (Room Temperature Sensor)
      *b Sensor Area
      *c Resistance (kΩ)
      *d Temperature (°C (°F))

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (+) - 2 (-) 10°C (50°F) 3.00 to 3.73 kΩ
      1 (+) - 2 (-) 15°C (59°F) 2.45 to 2.88 kΩ
      1 (+) - 2 (-) 20°C (68°F) 1.95 to 2.30 kΩ
      1 (+) - 2 (-) 25°C (77°F) 1.60 to 1.80 kΩ
      1 (+) - 2 (-) 30°C (86°F) 1.28 to 1.47 kΩ
      1 (+) - 2 (-) 35°C (95°F) 1.00 to 1.22 kΩ
      1 (+) - 2 (-) 40°C (104°F) 0.80 to 1.00 kΩ
      1 (+) - 2 (-) 45°C (113°F) 0.65 to 0.85 kΩ
      1 (+) - 2 (-) 50°C (122°F) 0.50 to 0.70 kΩ
      1 (+) - 2 (-) 55°C (131°F) 0.44 to 0.60 kΩ
      1 (+) - 2 (-) 60°C (140°F) 0.36 to 0.50 kΩ

      Note


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


      • When measuring the resistance, make sure the sensor temperature is the same as the ambient temperature.

      Tech Tips

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

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