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

    Standard resistance:
    Tester Connection
    Condition
    Specified Condition
    e1-5 - e1-6
    -10°C (14°F)
    7.30 to 9.10 kΩ
    e1-5 - e1-6
    -5°C (23°F)
    5.65 to 6.95 kΩ
    e1-5 - e1-6
    0°C (32°F)
    4.40 to 5.35 kΩ
    e1-5 - e1-6
    5°C (41°F)
    3.40 to 4.15 kΩ
    e1-5 - e1-6
    10°C (50°F)
    2.70 to 3.25 kΩ
    e1-5 - e1-6
    15°C (59°F)
    2.14 to 2.58 kΩ
    e1-5 - e1-6
    20°C (68°F)
    1.71 to 2.05 kΩ
    e1-5 - e1-6
    25°C (77°F)
    1.38 to 1.64 kΩ
    e1-5 - e1-6
    30°C (86°F)
    1.11 to 1.32 kΩ
    NOTICE:
    1. Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
    2. When measuring, the sensor temperature must be the same as the ambient temperature.
    HINT:
    As the temperature increases, the resistance decreases (see the graph).
    If the resistance is not as specified, replace the evaporator temperature sensor.
