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:

NOTICE:
* 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 cooler thermistor (room temperature sensor).
