P2073 OBD-II: Manifold Absolute Pressure/Mass Air Flow - Throttle Position

What Does P2073 Code Mean?

OBD-II Code P2073 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 P2073 is set.
