Description
The no. 1 Cooler thermistor (evaporator temperature sensor) is installed on the evaporator in the air conditioning unit to detect the temperature of the cooled air that has passed through the evaporator and to control the air conditioner. It sends signals to the air conditioning amplifier. The signals change in accordance with the resistance of the no. 1 Cooler thermistor (evaporator temperature sensor). As the temperature decreases, the resistance increases. As the temperature increases, the resistance decreases. The air conditioning amplifier applies a voltage (5 v) to the no. 1 Cooler thermistor (evaporator temperature sensor) and reads voltage changes as changes in the resistance of the no. 1 Cooler thermistor (evaporator temperature sensor). This sensor is used for frost prevention.

Inspection procedure
Ok: the display is as specified in the normal condition column.
Standard resistance
Notice:
Hint:
As the temperature increases, the resistance decreases (see the graph).
Replace air conditioning harness assembly
Using the “setup” menu (“bluetooth*” menu)
Registering a bluetooth® device in the system allows the system
to function. The following functions can be used for registered
devices:

Read data list
Hint:
Using the intelligent tester's data list allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshooting is one way to save time.

Reassembly
Install evaporator temperature sensor
Notice:
If reusing the evaporator, do not insert the sensor to
a location where the sensor was previously inserted.
Insert the sensor within range c shown in the
illustration.
Install the evaporator temperature sensor as shown
