MASS AIR FLOW (MAF) SENSOR INSPECTION [SKYACTIV-G 2.0]
Visual Inspection
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
2. Remove the MAF sensor/IAT sensor No.1. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
3. Visually inspect the MAF sensor for the following:
-
Damage, cracks, dirt
-
Rusted sensor terminal
-
Bent sensor terminal
-
If there is any malfunction, repair or replace the MAF sensor/IAT sensor No.1. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
Voltage Inspection
1. Remove the MAF sensor/IAT sensor No.1 without disconnect the connector. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
2. Connect the M-MDS to the DLC–2.
3. Switch the ignition ON (engine off).
4. 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. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)].)
-
If not as verified, replace the MAF sensor/IAT sensor No.1. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
