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

1. Disconnect the volume air flow sensor connectors.
2. Measure resistance between terminals 5 and 6.

Temperature [°C (°F)] Resistance (K ohms)

0 (32) 5.3 - 6.7
20 (68) 2.3 - 3.0
80 (176) 0.30 - 0.42





3. Measure resistance while heating the sensor using a hair drier.

Higher Smaller

4. If resistance does not decrease as heat increases the resistance remains unchanged, replace the volume air flow sensor assembly.
