Cause:
Faulty Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor
Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor harness is open or shorted
Barometric Pressure sensor and Turbocharger/Supercharger Inlet Pressure sensor circuit poor electrical connection

Symptoms:
