P0109 2009 FORD FUSION - Manifold Absolute Pressure/Barometric Pressure Sensor Intermittent
When is the code detected?The sensor signal to the ECM is failing intermittently.
P0109 2009 Ford Fusion DescriptionThe Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. In some vehicles the absolute pressure sensor is built into ECM.
