Engine: MaxxForce DT (2010 & Newer)

SPN: 3719
FMI: 16
Description: DPF Soot Load – Moderate (level 2/3)
Troubleshooting:
The purpose of the Aftertreatment (AFT) System is to catalyze carbon monoxide (CO), Oxides
of Nitrogen (NOx), and Hydrocarbons (HC). The Diesel Particulate Filter (DPF) will capture
soot and other particulates exiting the exhaust pipe. Once the DPF is full, it is heated and the
soot trapped inside is burned more efficiently than an exhaust system without an AFT system.
Probable causes:
1) Level 2 DPF regeneration required

Description: DPF Soot Load – Severe De-Rate
Troubleshooting:
The purpose of the Aftertreatment (AFT) System is to catalyze carbon monoxide (CO), Oxides
of Nitrogen (NOx), and Hydrocarbons (HC). The Diesel Particulate Filter (DPF) will capture
soot and other particulates exiting the exhaust pipe. Once the DPF is full, it is heated and the
soot trapped inside is burned more efficiently than an exhaust system without an AFT system.
Probable causes:
1) Level 3 DPF plugged
2) Remove DPF for servicing

Description: DOC/DPF Inlet unable to achieve light off temperature
Troubleshooting:
The purpose of the Aftertreatment (AFT) System is to catalyze carbon monoxide (CO), Oxides
of Nitrogen (NOx), and Hydrocarbons (HC). The Diesel Particulate Filter (DPF) will capture
soot and other particulates exiting the exhaust pipe. Once the DPF is full, it is heated and the
soot trapped inside is burned more efficiently than an exhaust system without an AFT system.
Probable causes:
1) Active regeneration SPN / FMI Code inhibitor
2) Biased DPFDP sensor or circuit
3) Engine unable to build enough heat to the DOC
4) DOC failure
5) Downstream Injection (DSI) failure to inject fuel to the exhaust
6) DPF failure

Description: DPF regenerations are occurring too frequently
Troubleshooting:
The purpose of the Aftertreatment (AFT) System is to catalyze carbon monoxide (CO), Oxides
of Nitrogen (NOx), and Hydrocarbons (HC). The Diesel Particulate Filter (DPF) will capture
soot and other particulates exiting the exhaust pipe. Once the DPF is full, it is heated and the
soot trapped inside is burned more efficiently than an exhaust system without an AFT system.
Probable causes:
1) Low Turbocharger Boost Levels
2) Turbocharger boost leaks
3) Exhaust Gas Recirculation (EGR) high flow
4) Injector coking
5) Ash in DPF
6) Exhaust system leaks
7) Engine Compression Brake (ECB) is not relieving pressure
8) Valve Lash
9) Air / Fuel ratio is incorrect
10) DPFDP reading high
