DESCRIPTION:Selective catalytic reduction (SCR) abnormal temperature rise. MONITORED PARAMETER:SCR inlet temperature, SCR outlet temperature. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Parked regeneration. PROBABLE CAUSES:1. Inspect the entire air intake system for leaks, including the charge air cooler.2. Intake manifold pressure/temperature sensor.3. Intake manifold pressure/temperature sensor connector/harness. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 5298 FMI 14 (ACM) Selective Catalytic Reduction Catalyst Abnormal Temperature Rise Detroit DD16 GHG14 (2014-16) Fault Code: SPN 5246 FMI 16 (ACM) Regulatory Fault Ignored – Final Action Pending Detroit DD16 GHG14 (2014-16) Fault Code:...

DESCRIPTION:Intake manifold pressure low. MONITORED PARAMETER:Intake manifold pressure. TYPICAL ENABLING CONDITIONS:1. Intake psi2. CAC psi3. Engine speed MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% NOTE: The MCM monitors the rail pressure and when rail pressure is less tha n200 bar, this code is set. PROBABLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2. Pressure limiting valve leakage (internal).3. Fuel filter integrity (loose caps, plugged filters).4. Fuel supply issues (fuel level, fuel aeration, leaking fuel lines, fuel restrictions).5. Intermittent loss of engine speed signal.6. High pressure...

DESCRIPTION:Fuel quantity high detected. MONITORED PARAMETER:Injector quantity TYPICAL ENABLING CONDITIONS:Steady state drive & no regen. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two minutes DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Steady engine RPM 1400 – 1500 (2 minute). NOTE: If any other fault codes are active, fix those first. PROBABLE CAUSES:1. failed intake manifold temperature sensor.2. Intake manifold temperature sensor connector/harness.3. EGR delta P sensor.4. EGR delta P sensor connector/harness.5. EGR system leaks (Check for soot).6. Remove the DPF and check for blockage or contamination (Coolant, fuel, oil, etc…).7. Check the entire exhaust system (including the EGR)...

NOTE: This fault is caused by low power on cylinder #1. Motor control module (MCM) adjusts injector pulse for smooth idle – min valve reached. DESCRIPTION:Cylinder #1 engine smoothness control quantity low. MONITORED PARAMETER:Cylinder 1 fueling error. TYPICAL ENABLING CONDITIONS:Engine smoothness control. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:MIL ENGINE REACTION:None POSSIBLE CAUSES:The entry conditions for this code are:1. Engine speed is above low idle.2. All cylinders are active, no fault reactions.3. Engine speed/torque is steady. This fault can occur due to the conditions listed below:1. Drivetrain vibrations.2. Cylinder kit failure.3. Valve train failure.4....
