Function Inspection
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Display the PCM PID [MAF]. (Refer to [PID/DATA MONITOR INSPECTION ] in the troubleshooting information.) (Refer to [PID/DATA MONITOR TABLE [PCM (SKYACTIV-G 2.5T)] ] in the troubleshooting information.)
- 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 2.5T] .)MASS AIR FLOW SENSOR SPECIFICATIONS (STANDARD)
