NOTE: For 2011 this code sets after SPN 5246/FMI 15 is present and the vehicle has been driven for 220 miles. NOTE: For 2010 this code sets after SPN 5246/FMI 15 is present and the vehicle has been driven for 30 hours or 1500 miles. DESCRIPTION:Regulatory fault ignored – final action pending. MONITORED PARAMETER:SCR and DPF sensors. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:40% derate, Limited to 55 MPH. VERIFICATION:1. Parked SCR efficiency test for extended SCR faults.2. High idle regeneration for DPF and NOx faults. NOTE: For 2010 emission engines,...

DESCRIPTION:This fault code sets when the motor control module (MCM) detects that there is EGR pressure when the engine is not running. MONITORED PARAMETER:EGR delta pressure. TYPICAL ENABLING CONDITIONS:Coolant temperature greater than 80°C (176°F) and ignition is cycled off for 10 seconds. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:15 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:1. Run the engine until the coolant temperature is greater than 80°C (176°F).2. Turn the ignition off for 15 seconds.3. Turn the ignition on as a recheck for the fault code. PROBABLE CAUSES:1. EGR delta p sensor failure.2. EGR delta...

NOTE: This code sets after SPN 5246/FMI 15 is present and the speed limit has been reduced to 55 mph. DESCRIPTION:Regulatory fault ignored – final action pending. MONITORED PARAMETER:SCR and DPF sensors. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:40% derate, limited to 55 mph. VERIFICATION:1. Parked SCR efficiency test for extended SCR faults.2. High idle regeneration for DPF and NOx faults. NOTE: If code 3364-xx present, fix that first. PROBABLE CAUSES:1. Check all DEF supply lines for damage or leaks.2. DEF tank is contaminated with gas, diesel, water, etc…3. SCR outlet...

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)...
