Detroit DD16 GHG14 (2014-16) Fault Code: SPN 411 FMI 2 (MCM) Exhaust Gas Recirculation Delta P Sensor Out of Calibration

DESCRIPTION:
EGR delta pressure sensor out of calibration.

MONITORED PARAMETER:
EGR delta pressure.

TYPICAL ENABLING CONDITIONS:
Coolant temperature greater than 80°C (176°F).

MONITOR SEQUENCE:
None

EXECUTION FREQUENCY:
Continuous when enabling conditions met.

TYPICAL DURATION:
15 seconds

DASH LAMPS:
1. MIL
2. CEL

ENGINE REACTION:
Derate

VERIFICATION:
1. Coolant temperature greater than 80°C (176°F).
2. Then engine off for 15 seconds.
3. Then Key on.

PROBABLE CAUSES:
1. EGR delta p sensor failure.
2. EGR delta p connector/harness.
3. EGR delta p pressure ports blocked.
