FRONT EVAPORATOR TEMPERATURE SENSOR(for DENSO Made) INSPECTION

PROCEDURE


  1. INSPECT NO. 1 COOLER THERMISTOR


    1. Check the resistance.


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

        A001XM9C01
        *a

        Component without harness connected

        (No. 1 Cooler Thermistor)

        		 *b Sensing Portion
        *c Resistance (kΩ) *d Temperature (°C (°F))
        *e Allowable Range - -
        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 -10°C (14°F) 7.30 to 9.10 kΩ
        -5°C (23°F) 5.65 to 6.95 kΩ
        0°C (32°F) 4.40 to 5.35 kΩ
        5°C (41°F) 3.40 to 4.15 kΩ
        10°C (50°F) 2.70 to 3.25 kΩ
        15°C (59°F) 2.14 to 2.58 kΩ
        20°C (68°F) 1.71 to 2.05 kΩ
        25°C (77°F) 1.38 to 1.64 kΩ
        30°C (86°F) 1.11 to 1.32 kΩ

        If the resistance is not as specified, replace the No. 1 cooler thermistor.

        Note


        • Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.

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

        Tech Tips

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

        If the specified condition is not met, replace the No. 1 cooler thermistor.
