Airflow Sensor
Measure voltage between terminals No. 3 (Green/White wire on 1.5L and 2.4L, Red/Green wire on 3.0L) and No. 6 (Brown wire) of airflow sensor connector. See Fig 1 . Warm engine to normal operating temperature and slow idle, while measuring voltage between terminals No. 3 and 6. With engine at idle and at 3000 RPM, 2.7-3.2 volts should be present. If voltage is not within specification, replace airflow sensor.
