MASS AIR FLOW (MAF) SENSOR INSPECTION [AJ (3.0L Duratec)]

Note

• Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See Troubleshooting Procedure.)

Visual Inspection

1. Verify the following items of the MAF sensor.

• Damage, cracks

• Rusted sensor terminal

• Bent sensor terminal

- If there is any malfunction, replace the MAF sensor. (See MASS AIR FLOW (MAF) SENSOR REMOVAL/INSTALLATION [AJ (3.0L Duratec)].)

Voltage Inspection

1. Remove the MAF sensor with the connector still connected.

2. Turn the ignition switch to the ON position.

3. Verify that the MAF sensor output voltage (WDS monitor item: MAF) changes when wind is introduced gradually to the sensor part of the MAF sensor.

• If it cannot be verified even though the related harnesses have no malfunction, replace the MAF sensor. (See MASS AIR FLOW (MAF) SENSOR REMOVAL/INSTALLATION [AJ (3.0L Duratec)].)
