Mazda CX-5 Service & Repair Manual: Mass Air Flow (MAF) Sensor

Mazda CX-5 Service & Repair Manual / Engine / Intake / 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.
