Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
AMBIENT TEMPERATURE SENSORON-VEHICLE INSPECTION
1. INSPECT A/C ROOM TEMPERATURE SENSOR
a. Remove the A/C room temperature sensor.
b. Disconnect the connector from the A/C room temperature sensor.
Part 1:
Part 2:
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 value is not as specified, replace the sensor.
