P006C
PowertrainMAP - Turbocharger/Supercharger Inlet Pressure Correlation
The engine control module has detected that the manifold absolute pressure sensor and the turbocharger or supercharger inlet pressure sensor are reporting mismatched readings, typically indicating a calibration or correlation issue between the two pressure sensors.
