Cabin Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: ROOM TEMPERATURE SENSOR (for Automatic Air Conditioning System): INSPECTION

1. INSPECT ROOM TEMPERATURE SENSOR





(a) Measure the resistance of the sensor.

Standard resistance:





NOTICE:
* Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
* When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
HINT
As the temperature increases, the resistance decreases (see the graph).

If the result is not as specified, replace the room temperature sensor.
