Diagnosis And Testing - Boost Pressure Sensor
WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
If the boost pressure sensor fails, the PCM records a DTC into memory and continues to operate the engine in one of the three limp-in modes. When the PCM is operating in this mode, a loss of power will be present, as if the turbocharger was not operating. The best method for diagnosing faults with the boost pressure sensor is with a scan tool. Refer to the appropriate Diesel Powertrain Diagnostic information for more information.
Refer to On-Board Diagnostics in EMISSIONS CONTROL for a list of Diagnostic Trouble Codes (DTCs) for certain fuel system components.
