2) Location and Components
HFM sensor
Used as a main map value to control the EGR.
The coolant temperature, engine rpm, engine
load, intake air temperature (HFM: decreased at
(atmospheric pressure sensor: altitude
compensation) are used as auxiliary map values.
EGR pipe
Transports the exhaust gas from the EGR cooler
and EGR bypass valve to the intake duct.
E-EGR cooler and bypass valve
The cooler lowers the high temperature of the
exhaust gas and the bypass valve directly
supplies the exhaust gas to the intake duct
without passing through the EGR cooler to
reduce the emission of exhaust gas before
warming up the engine.
E-EGR valve
Receives the electric signal from the ECU to
control the valve.

Front EGT sensor
Measures the temperature of
DOC.
The DOC performs the redox
reaction at between 300 and
sensor monitors the
temperature of DOC.
Differential pressure sensor
Measures the pressure values
of before and after the CDPF.
The pressure difference
between before and after the
CDPF is measured by the
differential pressure sensor (If
PM is collected in the CDPF,
the pressure difference
between before and after the
CDPF exceeds the specified
value).
Rear EGT sensor
Measures the temperature of
DPF.
The DPF burns the soot with
hot exhaust gases
(regeneration) at around
sensor monitors the
temperature of DPF.
Injector (C3I)
Controls the post-injection.
Electric throttle body
Controls the intake air
volume.

20 Times of CDPF regeneration
start (soot mass from engine)0 - The ECU calculates the soot mass from
engine in consideration of the engine RPM,
based on the ECU base MAP. The ECU
regenerates the CDPF automatically when it
determines that the accumulated soot is
about 36 g or greater. (The more city driving,
the greater value is) The times of
regeneration is displayed cumulatively.
21 Times of CDPF regeneration
start (collected soot mass)0 - The ECU calculates the soot mass from
engine in consideration of the engine RPM,
based on the ECU base MAP. The ECU
regenerates the CDPF automatically when it
determines that the accumulated soot is
about 24 g or greater. (The more city driving,
the greater value is) The times of
regeneration is displayed cumulatively.
22 Times of CDPF regeneration
start (driven distance)0 - The ECU regenerates the CDPF
automatically when the driving distance
reaches about 1,000 km or longer. (The
more high-speed driving, the greater value is)
The times of regeneration is displayed
cumulatively.
23 Times which CDPF re-
regeneration start is
requested0 - When the regeneration should be stopped
and started again according to the exhaust
gas temperature, start condition and vehicle
speed during CDPF regeneration, the times
of re-regeneration is displayed cumulatively.
24 Times which SIW forced
CDPF regeneration is
requested0 - The times which the technician carried out
the forced regeneration using the SIW
program is displayed cumulatively.
25 Times of ECU replacement 1 - The times of ECU initialization is displayed
cumulatively.
The ECU calculates the data of 4 items from No. 19 to No. 22 (map value calculated by the ECU) to
carry out the CDPF regeneration and the regeneration event map values of 4 items between No. 19
to No. 22 will be reset. (times of regeneration start is stored normally)
In the event of ECU initialization, the data of items from No. 1 to No. 24 will be reset. A.
