Ford Escape: Intake Air Distribution and Filtering / Description and Operation - Intake Air Distribution and Filtering - Overview
Overview
The
air intake system cleans intake air with a replaceable, dry-type engine
Air Cleaner (ACL) element made of treated, pleated paper. A new Air
Cleaner (ACL) element must be installed periodically as scheduled.
Engine performance and fuel economy are adversely affected when maximum
restriction of the Air Cleaner (ACL) element is reached.

System Operation
Adaptive Airflow
Some vehicles equipped with electronic throttle control (ETC) have
an adaptive airflow strategy that allows the PCM to correct for changes
in the airflow. During idle, the PCM monitors the throttle angle and
airflow. If the airflow is determined to be less than expected, the PCM
adjusts the throttle angle to compensate.
The PCM
only learns the adaptive a..
