Detroit DD13 EPA07 (2007-09) Fault Code: SPN 411 FMI 13 (MCM) EGR Delta Pressure Sensor Out of Calibration
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 p connector/harness.3. EGR delta p pressure ports blocked.
