Code P0107 2002 Ford F150 Description

The P0107 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates that the Barometric (BARO) or Manifold Absolute Pressure (MAP) sensor is detecting a low voltage signal. The BARO sensor measures the atmospheric pressure outside the vehicle, while the MAP sensor measures the pressure within the intake manifold. These sensors play a crucial role in the engine control system, providing data to the engine control module (ECM) to calculate air/fuel mixture, ignition timing, and other parameters necessary for optimal engine performance.
