This sensor is mounted in air cleaner assembly. The sensor measures airflow rate through the air cleaner and sends a proportionate electrical signal to ECU. The ECU uses airflow sensor information for controlling fuel delivery and the secondary air management. On Conquest and Starion intercooled models, an atmospheric pressure pick-up nipple (leading to atmospheric pressure switching solenoid valve) has been added to air cleaner and locations of oil separator and breather nipple have been changed.
