Description of Flash Code 47
Flash Code 47 indicates that the ECM has detected that the fuel pressure, air inlet pressure, or turbo boost pressure has exceeded a programmed operating range. This normally occurs due to a mechanical fault in the air system or fuel system of the engine. See Figure "Fuel Pressure Sensor " , for the fuel pressure sensor.
Note: Not all engines use a fuel pressure sensor.
For gas engines, code 47 indicates that the air inlet pressure has exceeded a calibration limit programmed in the ECM.
For diesel engines, code 47 indicates that the turbo boost pressure has exceeded a calibration limit programmed in the ECM.
