Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 27
FMI: 0
Description: EGRP fault: over temperature
Troubleshooting:
The Exhaust Gas Recirulation valve is a part of the EGR system that is used to reduce the
formation of NOX. The Exhaust Gas Recirculation Valve recirulates exhaust back into the
intake stream. Exhaust gases that have already burned do not burn again which cools
combustion and reduces NOX.
Probable Causes:
1) Exhaust Gas Recirculation (EGR) over heated
2) Low coolant flow through EGR
3) Failed EGR Cooler
4) Failed EGR valve

Description: EGRP signal Out of Range HIGH
Troubleshooting:
The Exhaust Gas Recirulation valve is a part of the EGR system that is used to reduce the
formation of NOX. The Exhaust Gas Recirculation Valve recirulates exhaust back into the
intake stream. Exhaust gases that have already burned do not burn again which cools
combustion and reduces NOX.
Probable Cause:
1) B+ over 18 volts to EGR valve
2) Jump start with 24-volt system or generator
3) Defective alternator
4) Battery charger on boost mode

Troubleshooting:
The Exhaust Gas Recirulation valve is a part of the EGR system that is used to reduce the
formation of NOX. The Exhaust Gas Recirculation Valve recirulates exhaust back into the
intake stream. Exhaust gases that have already burned do not burn again which cools
combustion and reduces NOX.
Probable causes:
1) EGR valve defective power connection
2) High resistance contacts
3) Low battery voltage
4) Defective charging system

Description: EGRP does not agree with commanded position
Troubleshooting:
The Exhaust Gas Recirulation valve is a part of the EGR system that is used to reduce the
formation of NOX. The Exhaust Gas Recirculation Valve recirulates exhaust back into the
intake stream. Exhaust gases that have already burned do not burn again which cools
combustion and reduces NOX.
Probable causes:
1) EGR valve motor internal duty cycle > 95 %
2) EGR valve motor stuck
3) Deposits on EGR valve
4) Stuck or sticking EGR valve
