Intake Air Temperature Sensor
- Sensor is incorporated in airflow sensor assembly inside air filter housing. Disconnect airflow sensor connector. See Fig 1 .
- Measure resistance between terminals No. 4 and 6 of airflow sensor connector (sensor side of connector).
- Replace airflow sensor assembly if air temperature sensor resistance is not within specification. See INTAKE AIR TEMPERATURE SENSOR RESISTANCE
