INSPECTION

PROCEDURE

1. INSPECT NO. 1 COOLER THERMISTOR

(a) Check the resistance.

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

Component without harness connected

(No. 1 Cooler Thermistor)

Sensing Portion

Resistance (kΩ)

Temperature (°C (°F))

Allowable Range

Standard Resistance:

Tester Connection	Condition	Specified Condition
h5-1 - h5-2	-10°C (14°F)	7.30 to 9.10 kΩ
h5-1 - h5-2	-5°C (23°F)	5.65 to 6.95 kΩ
h5-1 - h5-2	0°C (32°F)	4.40 to 5.35 kΩ
h5-1 - h5-2	5°C (41°F)	3.40 to 4.15 kΩ
h5-1 - h5-2	10°C (50°F)	2.70 to 3.25 kΩ
h5-1 - h5-2	15°C (59°F)	2.14 to 2.58 kΩ
h5-1 - h5-2	20°C (68°F)	1.71 to 2.05 kΩ
h5-1 - h5-2	25°C (77°F)	1.38 to 1.64 kΩ
h5-1 - h5-2	30°C (86°F)	1.11 to 1.32 kΩ

NOTICE:

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.

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