Intake Air Temperature Sensor

Disconnect airflow sensor connector. Check intake air temperature sensor by measuring resistance at terminals No. 2 and 4. See Fig 1 . See INTAKE AIR TEMPERATURE SENSOR SPECIFICATION table. Replace airflow sensor assembly if readings are not to specification. Using a hair dryer, heat sensor. As temperature increases, resistance of the sensor should decrease. If not, replace sensor.
