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

1. Disconnect the volume air flow sensor connectors.




2. Measure resistance between terminals 5 and 6.

Standard value:
2.3-3.0 kOhms @ 20°C (68°F)
0.30-0.42 kOhms @ 80°C (176°F)




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.
