Detroit Diesel code 137 typically indicates a problem with the engine's fuel system, specifically related to the fuel supply or pressure. This code can be triggered by issues such as a clogged fuel filter, a malfunctioning fuel pump, or low fuel pressure. To resolve the issue, it's important to inspect the fuel system components and ensure they are functioning properly. Always refer to the specific service manual for detailed diagnostic procedures.
