Scr torque derate.

Jan 7, 2024 · DEF Dosing Valve Failure. The dosing valve is responsible for injecting DEF into the exhaust stream and, if it malfunctions, your engine will be forced into derate. This is because the ECU will not receive the correct information about the amount of DEF in the system. As a result, will not be able to properly regulate the engine’s emissions.

SPN 4364/FMI 1 Description This fault code sets when the Aftertreatment Control Module (ACM) detects that the NOx conversion is lower than a calibrated threshold Monitored Parameter Selective Catalyst Reduction (SCR) Inlet NOx sensor, SCR outlet NOx sensor Typical Enabling Conditions Diesel Exhaust Fluid (DEF) dosing enabled, 1000 - 1500 rpm ...Performing an ECM reset can help in resetting the engine’s parameters and resolving the derate condition. Follow these steps: Access the ECM settings section in Cummins Insite. Select the option to perform an ECM reset. Follow the on-screen prompts to initiate the reset process. Wait for the reset process to complete.

The Cummins engine is designed with a "torque derate curve". This basically means that as certain conditions are met, the ECM will automatically adjust the torque output of the motor to compensate. These conditions can be changes in atmospheric temperature and pressure, fuel quality, and altitude. By reducing torque output, the engine is ... For a Urea Quality Sensor fault, the steps are: warning, torque derate 1, torque derate 2 and severe derate. The first step, warning, will turn on a check engine light and/or a MIL light. Torque derate 1 reduces engine power by 25%; while torque derate 2 reduces engine power by 40%.
