Code P2463 Chevrolet Description

The soot particles accumulate in the channels of the Diesel Particulate Filter (DPF) and are burned off at regular intervals, through a process called regeneration or cleaning. The DPF cleaning process prevents the DPF from clogging. Excess soot in the filter can cause a drop in engine performance and crack the filter during regeneration. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the Diesel Particulate Filter is clogged and needs service regeneration.
