P0090 Code: Fuel Pressure Regulator Control Circuit / OpenDiagnostic trouble code (DTC) P0090 stands for “Fuel Pressure Regulator Control Circuit/Open.” This code sets when the PCM has determined that there is an open control circuit in the electronic fuel pressure regulator. This code may also set when the PCM is unable to control the fuel pressure regulator, or P008A Code: Low Pressure Fuel System Pressure – Too LowDiagnostic trouble code (DTC) P008A stands for “Low Pressure Fuel System Pressure- Too Low.” This trouble code sets when the powertrain control module (PCM) has detected that the fuel pressure is too low within the low fuel system. In some cases, low fuel volume or insufficient flow may also trigger P0149 Code: Fuel Timing ErrorDiagnostic trouble code (DTC) P0149 stands for “Fuel Timing Error.” This code sets when the powertrain control module (PCM) has detected a fuel pressure signal indicating a malfunction with the fuel pump timing. The PCM may also store this code if the actual fuel pressure and the commanded fuel pressure
