The control module detected a fault associated with the Particulate Filter Restriction - Soot Accumulation circuit or function; the stored code identifies the affected component rather than a single failure mode.
Symptoms
MIL or DPF warning illuminated
Possible reduced power or limp mode
Possible frequent regeneration attempts
Possible causes
Wiring
DPF pressure sensor
Pressure hoses
Wiring
Clogged DPF
SCR system malfunction
High
low exhaust temperature
Defective EGR valve / circuit
Low fuel
PCM failure
Recommended checks
Read soot load, ash load and differential pressure values
Check differential pressure sensor and hoses
Verify exhaust gas temperature sensor readings
Check for related injection, EGR or boost codes
Verify regeneration conditions can be met (trip profile)
Powertrain: engine, transmission and driveline systems.
