The readings for the turbocharger inlet pressure sensor will be approximately the same value that is reported by the atmospheric pressure sensor. The approximate same value readings will occur while the engine is not running. If the readings do not agree, troubleshoot the sensor circuit for the suspect sensor.

DTC with associated derate? Data logged in this histogram? Interpretation
No Yes Derate was probably caused by the exhaust temperature derate.
