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







INTAKE AIR TEMPERATURE SENSOR CHECK
1. Disconnect the volume air flow sensor connectors




2. Measure resistance between terminals 5 and 6.




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