Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2791 FMI 18 (MCM) Smart Remote Actuator 3 (EGR), Learn Span Too Small
Posted by PerDiezel Solutions on
DESCRIPTION:The fault code sets when the motor control module (MCM) detects that the exhaust gas recirculation (EGR) valve position is incorrect. MONITORED PARAMETER:EGR position error. TYPICAL ENABLING CONDITIONS:Engine running MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Engine idle NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. EGR delta p sensor.2. EGR delta p sensor pressure port.3. EGR delta p sensor harness/connector.4. Check EGR system for leaks.5. EGR valve actuator pull rod.6. EGR valve.7. Remove the EGR cooler hot pipe, EGR crossover pipe, and delivery pipe for excessive blockage.8. Air...

DESCRIPTION:The fault code sets when the motor control module (MCM) detects that the exhaust gas recirculation (EGR) valve position is incorrect. MONITORED PARAMETER:EGR position error TYPICAL ENABLING CONDITIONS:Engine running MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Engine idle PROBABLE CAUSES:1. If 110-0 is active, repair this first.2. Check for EGR exhaust leaks at the EGR valve actuator.3. Remove the actuator cooler lines and fittings, check for kinks/plugs or leaks.4. EGR valve actuator failure.
