Data confidence65%
The control module detected a fault associated with the Particulate Filter Regeneration Duration Bank 2 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
Excessive soot load beyond regeneration limits
Differential pressure sensor or hose fault
Failed or interrupted regenerations (short trips)
Exhaust leak upstream of the sensor
Underlying engine fault increasing soot output
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.
