Mazda CX-5 Service & Repair Manual: Evaporator Temperature Sensor [Full Auto Air Conditioner]

Purpose

• The evaporator temperature sensor detects the airflow temperature passing through the evaporator.

Function

• The evaporator temperature sensor converts the detected temperature to an electric signal.

Construction

• A thermistor-type evaporator temperature sensor has been adopted.

• A fin-thermo-type sensor has been adopted to the sensor area of the evaporator temperature sensor which inserts between the evaporator fins.

• The evaporator temperature sensor is installed to the A/C unit.

Operation

• The thermistor changes the resistance according to the surrounding temperature.

• The resistance decreases if the temperature increases, and conversely increases if the temperature decreases as shown in the figure.

Fail-safe

• Function not equipped.
