Home  id0140u3800700

Visual Inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

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 (WITH CYLINDER DEACTIVATION (E))].)

3.  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. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].)

Function Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Display the PID MAF. (See PID/DATA MONITOR INSPECTION.)

4.  Compare the voltage and flow rate indications for the PID MAF with the standard in the table indicated below.

•  If they do not match the standard, 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 (WITH CYLINDER DEACTIVATION (E))].)
