Detroit DD15 EPA10 (2010-13) Fault Code: SPN 2659 FMI 0 (MCM) Exhaust Gas Recirculation Flow Target Error Diagnostic – High Flow

DESCRIPTION:
Exhaust Gas Recirculation (EGR) flow target error – actual flow above the threshold of desired flow.

MONITORED PARAMETER:
EGR Mass Flow

TYPICAL ENABLING CONDITIONS:
1. Desired EGR mass flow greater than .08.
2. EGR in closed-loop control, CAC outlet temperature greater than 0°C (32°F).
3. Engine Speed 1080 to 2500 rpm.
4. Engine torque 200 to 2500 N·M (148 to 1894 lb·ft).
5. Coolant temperature greater than 65°C (149°F).
6. Ambient temperature greater than -8°C (17.6°F) Ambient.
7. Barometric pressure greater than 755 Mbar (11 psi).

MONITOR SEQUENCE:
None

EXECUTION FREQUENCY:
Always enabled

TYPICAL DURATION:
20

DASH LAMPS:
1. MIL
2. CEL

ENGINE REACTION:
Derate 25%

VERIFICATION:
1. Start engine.
2. Warm up such that coolant temperature greater than 65°C (149°F).
3. Ensure ambient temperature greater than -8°C (18°F).
4. Ambient Barometric pressure greater than 755 mbar (11 psi).
5. Desired EGR mass flow greater than .08.
6. EGR in closed-loop control.
7. CAC outlet temperature greater than 0°C (32°F).
8. Engine speed 1080 to 2500 rpm.
9. Engine torque 200 to 2500 N·m (148 to 1894 lb·ft).

PROBABLE CAUSES:
1. EGR delta p sensor.
2. EGR delta p harness/connector.
3. EGR delta p sensor port.
4. EGR valve.
