Air Flow Meter/Sensor: Testing and Inspection

MASS AIR FLOW (MAF) SENSOR INSPECTION [MZR 2.0, MZR 2.5]

Visual Inspection

1. Remove the battery cover. Removal and Replacement

2. Disconnect the negative battery cable. Removal and Replacement

3. Disconnect the MAF/IAT sensor connector.

4. Remove the MAF/IAT sensor. Service and Repair

5. Visually inspect the MAF/IAT sensor for the following:

- Damage, cracks, soiling
- Rusted sensor terminal
- Bent sensor terminal

- If there is any malfunction, repair or replace the MAF/IAT sensor. Service and Repair

Voltage Inspection

1. Remove the battery cover. Removal and Replacement

2. Disconnect the negative battery cable. Removal and Replacement

3. Remove the MAF/IAT sensor without disconnect the MAF/IAT sensor connector. Service and Repair

4. Reconnect the negative battery cable. Removal and Replacement

5. Connect the M-MDS to the DLC-2.






6. Switch the ignition to ON.

7. As the air gradually approaches the MAF detection part of the MAF/IAT sensor, verify that the MAF sensor output voltage (PID: MAF) varies. On-Board Diagnostic Test

- If not as verified, replace the MAF/IAT sensor. Service and Repair
