Cabin Temperature Sensor / Switch: Testing and Inspection

AIR CONDITIONING: ROOM TEMPERATURE SENSOR: INSPECTION

1. INSPECT ROOM TEMPERATURE SENSOR






(a) Remove the A/C room temperature sensor.
(b) Disconnect the connector from the A/C room temperature sensor.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:





NOTICE:
- Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
- When measuring, the sensor temperature must be the same as the ambient temperature.
HINT:
As the temperature increases, the resistance decreases (see the graph).
