MASS AIR FLOW (MAF) SENSOR INSPECTION [L3 R.H.D.]

Note

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

Visual Inspection

1. Visually inspect the MAF sensor for the following:

• Damage, cracks

• Rusted sensor terminal

• Bent sensor terminal

- If there is any malfunction, replace the MAF/IAT sensor.

Voltage Inspection

1. Remove the MAF/IAT 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 MAF sensor of the MAF/IAT sensor.

• If it cannot be verified even though the related wiring harnesses have no malfunction, replace the MAF/IAT sensor.
