Cabin Temperature Sensor / Switch: Testing and Inspection

HEATING / AIR CONDITIONING: ROOM TEMPERATURE SENSOR: INSPECTION

1. INSPECT COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)





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

Standard Resistance:





HINT
As the temperature increases, the resistance decreases (refer to the graph).

NOTICE:
* Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
* When measuring the resistance, make sure the sensor temperature is the same as the ambient temperature.

If the result is not as specified, replace the cooler thermistor (room temperature sensor).
