1. INSPECT FRONT EVAPORATOR TEMPERATURE SENSOR (NO. 1 COOLER THERMISTOR)


I103750E06
  1. Measure the resistance according to the value(s) in the table below.

    2.14 to 2.58 kΩ
    1 - 2
    20°C (68°F)
    1.71 to 2.05 kΩ
    1 - 2
    25°C (77°F)
    1.38 to 1.64 kΩ
    1 - 2
    30°C (86°F)
    1.11 to 1.32 kΩ

    NOTICE:
    1. Touching the sensor even slightly may change the resistance value. Hold the sensor connector.
    2. When measuring the resistance, the temperature of the sensor and the cooler thermistor must be the same.

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

    If the operation is not as specified, replace the front evaporator temperature sensor.
