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.
*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.
NOTICE:
HINT:
As the temperature increases, the resistance decreases (see the graph).
If the specified condition is not met, replace the No. 1 cooler thermistor.
