Description
Static plausibility check:
The exhaust temperature value from the
sensor before DOC, the exhaust
temperature value from the sensor after
DOC, the temperature 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
environment temperature sensor value:
The exhaust temperature value from the
sensor before DOC is lower than an
applicable environment temperature
threshold
Possible Cause
Static plausibility check:
The exhaust temperature value from the
sensor before DOC, the exhaust temperature
value from the sensor after DOC, the
temperature 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 ambient temperature < Threshold 4
difference between temperature ambient
temperature 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 (<
environmental temperature + Threshold 6)
Action
Check ambient temperature => value
plausible?
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?
