Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
Outside Temperature Sensor
Outside Temperature Sensor Location
1.
Remove the temperature sensor from the windshield wiper bracket.
2.
Place the sensor next to an accurate temperature gauge (thermometer) and allow enough time for the sensor and the gauge to adjust to the ambient
temperature.
3.
With a suitable ohmmeter, check the resistance of the sensor.
4.
Compare the readings with the temperature chart.
If the resistance is not within the specified range, replace the outside temperature sensor.
