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.
Evaporator Temperature Sensor Inspection [Manual Air Conditioner]
NOTE:
Inspect the evaporator temperature sensor when it is installed to the A/C
unit.

Handling Insufficient Refrigerant Level
If an insufficient refrigerant level is detected at troubleshooting, do
not charge (add) the refrigerant. Because an accurate amount of refrigerant
cannot be determined from the pressure indicated on the manifold gauge, never
charge the refrige ...
Tcs Off Switch Inspection
1. Remove the TCS OFF switch..
2. Verify that the resistance between the TCS OFF switch terminals B and C is
as indicated in the table.
If not as indicated in the table, replace the TCS OFF switch.

Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.
