SENSOR INSPECTION

Intake Air Temperature Sensor:

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 or the resistance remains unchanged replace the volume air flow sensor assembly.
