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:

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)].)
