Air Flow Meter/Sensor: Testing and Inspection
MASS AIR FLOW (MAF) SENSOR INSPECTION [SKYACTIV-G 2.0]
Visual Inspection
1. Remove the battery cover. Removal and Replacement
2. Disconnect the negative battery cable. Removal and Replacement
3. Disconnect the MAF sensor/IAT sensor No.1 connector.
4. Remove the MAF sensor/IAT sensor No.1. Service and Repair
5. Visually inspect the MAF sensor for the following:
- Damage, cracks, soiling
- Rusted sensor terminal
- Bent sensor terminal
- If there is any malfunction, repair or replace the MAF sensor/IAT sensor No.1. 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 sensor/IAT sensor No.1 without disconnect the 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 sensor/IAT sensor No.1, verify that the MAF sensor output voltage (PID: MAF) varies. On-Board Diagnostic Test
- If not as verified, replace the MAF sensor/IAT sensor No.1. Service and Repair
