DTC P2002 DPF
DTC P2002 DPF PFP:208D0
Component Description BBS002L6
DPF (Diesel Particulate Filter) is placed in oxidation catalyst assembly and traps PM (Particulate Matter) in
exhaust gas. DPF is formed in a honeycomb form made of ceramic. This structure facilitates to trap particulate
matter.
When the amount of particulate matter in the DPF reaches the specified level, the particulate matter needs to
be reduced through burning to maintain the DPF function. This reducing of particulate matter is called Regen-
eration and should be performed periodically. DPF can be effective for a long time through the cycle of trap-
ping particulate matter and regeneration.
On Board Diagnosis Logic BBS002L7
This self-diagnosis has the one trip detection logic.
The MI will not light up for this diagnosis.
NOTE:
If DTC P2002 is displayed with other DTC, first perform the trouble diagnosis for other DTC.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe.

(DPF) efficiency below
threshold
● Differential exhaust pressure exceeds a
standard level for more than 10 seconds.
● Exhaust gas temperature does not raise dur-
ing DPF regeneration.
● Oxidation catalyst with DPF
● Front exhaust gas temperature sensor
● Rear exhaust gas temperature sensor
Detected items Engine operating condition in fail-safe mode
Particulate matter over accumulation Engine speed will not rise more than 2,000 rpm due to the fuel cut.
