SPN 4752 FMI 0 is the Detroit DD Series (EPA 2007–Current) diagnostic trouble code that Detroit documents as “Exhaust Gas Recirculation (EGR) Cooler Low Efficiency”. This 2-page EPA10 fault-code sheet documents the monitored parameters and the 10% derate reaction, the dash-lamp indication and engine reaction, and the ordered troubleshooting steps used to confirm and clear the condition. The monitor uses the intake manifold and charge air cooler outlet temperature sensors, the engine reaction is a 10% derate with the MIL and CEL on, and the procedure separates a temperature-sensor fault from a blocked or leaking EGR cooler.

Applicable truck models
This fault-code procedure applies to trucks powered by the Detroit DD13, DD15 and DD16 engines on the DD Series (EPA 2007–Current) platform. With the tool connected and the key on, the technician checks whether the intake manifold air temperature reads above 93°C, inspects the sensor connector for bent, spread or corroded pins, looks for external EGR leakage such as soot or coolant deposits, and removes the EGR hot pipe, crossover tube and mixer pipe to find build-up before cleaning and replacing the EGR cooler. Always confirm the engine family and EPA10 emissions level against the vehicle, and cross-check the latest procedure in the Detroit Power Service Literature on the official Detroit website.
Who needs this SPN 4752 FMI 0 manual
Diesel technicians, fleet maintenance teams and workshop owners diagnosing an EGR cooler low-efficiency fault or a 10% derate on an EPA10 DD engine on Detroit DD Series trucks use this sheet to work the fault in order instead of guessing. The methodical sensor-first approach avoids replacing a costly EGR cooler when the temperature sensor is the real fault.
