Air Temperature Sensor ( Ambient / Intake ): Testing and Inspection

Intake Air Temperature Sensor Inspection:

1. Disconnect the connectors on the combination Volume Air Flow Sensor/Intake Air Temperature Sensor.





Sensor Specifications:






2. Measure resistance between terminals 5 and 6.






3. Measure resistance while heating the sensor using a hair drier.
As the temperature increases, the resistance should decrease.
4. If resistance does not decrease as heat increases the resistance remains unchanged, replace the volume air flow sensor assembly.
