15. EVAPORATOR TEMPERATURE SENSOR
The evaporator temperature sensor detects the temperature of the cool air immediately through the evaporator in
the form of resistance changes, and outputs it to the A/C amplifier.
16. ROOM TEMPERATURE SENSOR
The room temperature sensor detects the cabin temperature based on changes in the resistance of its built-in
thermistor and sends a signal to the A/C amplifier.
17. AMBIENT TEMPERATURE SENSOR
The ambient temperature sensor detects the outside temperature based on changes in the resistance of its built-in
thermistor and sends a signal to the A/C amplifier.
18. SOLAR SENSOR (AUTOMATIC LIGHT CONTROL SENSOR)
The solar sensor (automatic light control sensor) detects the changes in the amount of sunlight and outputs it to
the A/C amplifier in the form of voltage changes.
19. A/C PRESSURE SENSOR
The A/C pressure sensor detects the refrigerant pressure and outputs it to the A/C amplifier in the form of
voltage changes.
