Cabin Temperature Sensor / Switch: Testing and Inspection
Room Temperature Sensor
ON-VEHICLE INSPECTION
1. INSPECT A/C ROOM TEMPERATURE SENSOR
a. Remove the A/C room temperature sensor.
b. Measure the resistance according to the value(s) shown 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 value is not as specified, replace the sensor.
