Diagnosis And Testing - Boost Pressure Sensor

WARNING: This page is about a different car, the 2019 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.

If the boost pressure sensor fails, the Powertrain Control Module (PCM) records a Diagnostic Trouble Code (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 Diesel Powertrain Diagnostic information for more information.
Refer to On-Board Diagnostics in Emissions Control System for a list of DTC's for certain fuel system components.
