Diagnostic Instructions
DTC Descriptor
DTC P242F 00: Diesel Particulate Filter
(DPF) Restriction - Not Regenerable
Circuit/System Description
The soot particles accumulate in the channels of the 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 filter can cause a drop in engine
performance and crack the filter during regeneration.
