Inspection INSPECTION PROCEDURE

1. INSPECT COOLER THERMISTOR SENSOR

(a) Check the resistance.

(1) Measure the resistance and check the results in accordance with the values in the table below.

Standard:

Tester Connection

Condition

Specified Condition

1 - 2

-10°C (14°F)

7.40 to 9.20 kΩ

1 - 2

-5°C (23°F)

5.65 to 7.00 kΩ

1 - 2

0 °C

4.35 to 5.40 kΩ

1 - 2

5 °C

3.40 to 4.20 kΩ

1 - 2

10 °C

2.68 to 3.30 kΩ

1 - 2

15 °C

2.10 to 2.60 kΩ

1 - 2

20 °C

1.66 to 2.10 kΩ

1 - 2

25 °C

1.32 to 1.66 kΩ

1 - 2

30 °C

1.05 to 1.35 kΩ

If the result is not as specified, replace the cooler thermistor sensor.

NOTICE:

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

HINT:

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