Cabin Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: ROOM TEMPERATURE SENSOR:

INSPECTION

1. INSPECT ROOM TEMPERATURE SENSOR






(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:





- Hold the sensor only by its connector. Touching the sensor may change the resistance value.
- When measuring, the sensor temperature must be the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph).
If the resistance is not as specified, replace the room temperature sensor.
