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

1. Disconnect air flow sensor connectors.
2. Measure resistance between terminals 4 and 6. Ohmmeter should indicate the following values:
a. At 32°F, ohmmeter should indicate 6.0k ohms.
b. At 68°F, ohmmeter should indicate 2.7k ohms.
c. At 176°F, ohmmeter should indicate 0.4k ohms.
3. If resistance values are not as specified, or resistance values do not change, replace air flow sensor.
