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 k Ohm [at 20°C (68°F)]
0.30 - 0.42 k Ohm [at 80°C (176°F)]





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

Normal condition:





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