Diesel Particulate Filter
(Exhaust Filter)
The Duramax engine is equipped
with a Diesel Particulate Filter (DPF)
that, by design, will filter or trap
particulates. The DPF is located
under the vehicle in the exhaust
system and looks like a catalyst.
Depending on a number of factors
monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids. When a
cleaning is needed, the engine
computer will initiate a cleaning
action by warming the exhaust gas
temperature. This feature has been
designed to operate automatically,
with limited operator involvement or
awareness.
Cleaning the DPF
(Exhaust Filter)
While the DPF cleaning is
automatically controlled by the
engine computer, the vehicle will
need to operate continuously for
approximately 30 minutes and at
speeds greater than 48 km/h
(30 mph) to clean the DPF
effectively. If the vehicle is returned
to idle during the cleaning process,
the driver may notice a slightly
different sound or a slightly elevated
engine idle speed. This is normal.
No action is required on the part of
the driver during a regular DPF
cleaning. See
Diesel Particulate
Filter (Exhaust Filter) on page 9
