MASS AIR FLOW (MAF) SENSOR [SKYACTIV-D 2.2]

id0140z7007000


Purpose/Function

•  Detects the intake airflow amount after it passes through the air cleaner as basic information for mainly determining the fuel injection amount.
•  Detects the intake airflow amount after it passes through the air cleaner and sends to the PCM as an intake airflow amount signal.

Construction

•  Installed on the air cleaner.

•  PCM restricts engine torque.
•  Inhibits the EGR control.
•  Inhibits the diesel particulate filter regeneration control.
•  The fast idle up correction for the idle speed control is inhibited.
•  Inhibits engine-stop by operating the i-stop function.
•  PCM restricts engine-transaxle integration control.
