Turbo Boost Sensor: Testing and Inspection
If the boost pressure sensor fails, the ECM records a DTC into memory and continues to operate the engine in one of the three limp-in modes. When the
ECM 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 the DRBIII(R) scan tool.
