Mazda CX-5 Service & Repair Manual: Mass Air Flow (MAF) Sensor
Purpose/Function
-
Detects the intake airflow amount introduced into the cylinder as basic information for mainly determining the fuel injection amount.
-
Detects the intake airflow amount introduced into the cylinder and inputs it to the PCM as an intake airflow amount signal.
Construction
-
Installed on the air cleaner.
-
A hot film has been adopted as the detecting element for detecting the intake airflow amount.
-
IAT sensor No.1 is integrated.
Operation
-
Inputs the signal, which fluctuates according to the intake airflow amount, to the PCM.
