1. INSPECT A/C AMBIENT TEMPERATURE SENSOR


    E106870E03
  1. Remove the A/C ambient temperature sensor.

  1. Disconnect the connector from the A/C ambient temperature sensor.

  1. 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

    NOTICE:
    1. Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
    1. When measuring, the sensor temperature must be the same as the ambient temperature.

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