Section 47.1
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.‪
