Cabin Temperature Sensor / Switch: Testing and Inspection
ON-VEHICLE INSPECTION
1. INSPECT REAR A/C ROOM TEMPERATURE SENSOR
a. Remove the rear A/C room temperature sensor
b. Disconnect the connector from the rear A/C room temperature sensor.
c. Measure the resistance according to the value (s) in the table.
NOTE:
-
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).
If the resistance is not as specified, replace the rear A/C room temperature sensor.
