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

If not within specifications, replace the volume air flow sensor.




3. Measure resistance while heating the sensor using a hair dryer.
4. If resistance does not decrease as heat increases, replace the volume air flow sensor assembly.
