Manifold Absolute Pressure - Turbocharger/Supercharger Boost Sensor "A" Correlation

The turbocharger boost pressure sensor reading does not match what the manifold pressure sensor is reporting, indicating a mismatch between the two. One or both sensors may be faulty, or there may be a mechanical issue with the turbocharger system. The engine cannot accurately control boost pressure without agreement between these sensors.
