Code P0109 2016 Ford F150 Description

The P0109 diagnostic trouble code (DTC) for a 2016 Ford F150 indicates an issue with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor, specifically an intermittent fault. The MAP sensor measures the pressure inside the intake manifold, providing crucial data to the engine control module (ECM) for determining the correct air-fuel mixture for combustion. The BARO sensor, on the other hand, measures the atmospheric pressure outside the vehicle, which is used by the ECM to adjust fuel delivery at different altitudes.
