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.

3.05 to 2.95 kΩ |
|
|
30°C (86°F) |
2.46 to 2.37 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.
