Description
Static plausibility check:
The exhaust temperature value from the
sensor before DOC, the exhaust temperature
value from the sensor after DOC, the temper-
ature value from the sensor before
SCR-Cat, the environment temperature and
the coolant engine temperature their ratios
to each other exceed their related thresh-
olds.
Dynamic plausibility check with environ-
ment temperature sensor value:
The exhaust temperature value from the
sensor before DOC is lower than an applica-
ble environment temperature threshold
The exhaust temperature value from the
sensor befor DOC
is above an applicable upper shutoff thresh-
old
TOxiCatUs_tShOffThresHiAds_C = Thresh-
old 1 in Normal and
Heatmodes
(TOxiCatUs_tShOffThresHiRgn_C = Thresh-
old 2
in stand-still)
The exhaust temperature value from the
sensor befor DOC
is above an applicable upper warning
threshold
TOxiCatUs_tWarnThresHi_C = Threshold
Oxidation catalyst upstream temperature
sensor: the voltage of sensor measured by
ECU is out of the target range
Oxidation catalyst upstream temperature
sensor: the voltage of sensor measured by
ECU is out of the target range
Possible Cause
Static plausibility check:
The exhaust temperature value from the sensor
before DOC, the exhaust temperature
value from the sensor after DOC, the tempera-
ture value from the sensor before
SCR-Cat, the environment temperature and the
coolant engine temperature their ratios
to each other exceed their related thresholds.
(difference between temperature after DOC and
temperature before DOC > Threshold 1
difference between temperature befor DOC and
before SCR > Threshold 2
difference between temperature after DOC and
before SCR < Threshold 3
difference between temperature after DOC and
ambinet temperature < Threshold 4
differnece between temperatur ambient tem-
perature and engine temperature <
Threshold 5)
Dynamic plausibility check with environment
temperature sensor value:
The exhaust temperature value from the sensor
before DOC is lower than an applicable
environment temperature threshold (< envi-
ronmental temperature + Threshold 6)
sensed temperature upstream DOC > shut-off
limit
Sensed temperature upstream DOC > warning
limit
The sensed raw voltage value
Exh_uRawTOxiCatUs is above
Exh_SRCTOxiCatUs.uMax_C
Shortcut to battery
The sensed raw voltage value
Exh_uRawTOxiCatUs is
below Exh_SRCTOxiCatUs.uMin_C
Shortcut to ground
Action
Check ambient temperature => value plausi-
ble?
upstream DOC sensor mounted within exhaust
line?
T upstream DOC sensor physically mounted in
correct position upstream DOC? (not
upstream SCR or downstream DOC?)
Check T upstream DOC sensor
Check other T-sensors within EAT-system
(Exh_tOxiCatDs & UCatUsT_tFlt_mp show
plausible values? No errors on them?
Check air path of engine: EGR-Valve, Intake-
Throttle,
Check Turbocharger and Piping each for leakage
and correct function
Check injectors: is an injector got stuck?
Exchange temperature sensor upstream DOC
