Air Flow Meter/Sensor: Testing and Inspection

MASS AIR FLOW (MAF) SENSOR INSPECTION [L5]

Visual Inspection

1. Disconnect the negative battery cable.

2. Disconnect the MAF/IAT sensor connector.

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

4. 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 MAF/IAT sensor without disconnect the MAF/IAT sensor connector.

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






3. Switch the ignition to ON.

4. As the air gradually approaches the MAF detection part of the MAF/IAT sensor, verify that the voltage (M-MDS PID: MAF) varies.

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