Code P0108 2012 Ford Fusion Description

The P0108 diagnostic trouble code (DTC) for a 2012 Ford Fusion indicates a high input from the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor. The MAP sensor measures the pressure inside the intake manifold, while the BARO sensor measures the atmospheric pressure outside the engine. The Engine Control Module (ECM) uses these readings to calculate air density and adjust fuel delivery and ignition timing accordingly.
