INSPECT NO. 3 COOLER THERMISTOR
Measure the resistance according to the value(s) in the table below.
| Standard Resistance | ||||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
If the result is not as specified, replace the cooler thermistor.
Note
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 the same as the ambient temperature.
Tech Tips
As the temperature increases, the resistance decreases (See the graph).
