What Does P2074 Code Mean?

    OBD-II Code P2074 is defined as a Manifold Absolute Pressure/Mass Air Flow - Throttle Position

    The Mass Air Flow (MAF) Sensor or Manifold Air Pressure Sensor allows the engine computer (PCM) to calculate how much air is actually flowing through the engine. The PCM monitors the throttle position and compares the actual MAF reading to what the reading should be. If the actually reading varies excessively from what it should be, code P2074 is set.
