Description
delta pressure across venturi in EGR line
below physical low limit
The sensed raw voltage
Air_uRawPEGRDeltaP is above the maxi-
mum threshold.
Range check cannot be done or
interrupted.
The sensed raw voltage value
Air_uRawPEGRDeltaP is above the mini-
mum threshold.
DFC is stored in EEPROM and status kept
until check is allowed
to be carried out again
DFC can be reset by service routine 216
EGR downstream temperature sensor: the
voltage of sensor measured by ECU is out of
the target range.
EGR downstream temperature sensor: the
voltage of sensor measured by ECU is out of
the target range.
Internal hardware monitoring: the ECU
finds an error during the access to its
EEPROM memory or works with an
alternative value
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
sensed value of venturi difference pressure <
low limit
EGR Delta pressure Sensor defect
EGR or wiring defect
EGR Delta pressure Sensor defect
deviation between desired O2 concentration
in intake air manifold
and the real O2-concentration within intake
air manifold > limit
Short circuit to battery. sensor voltage > limit Check wiring harness to TEGR-sensor.
Short circuit to ground or open load. sensor
voltage < limit
Section could not be erased
Action
Threshold for error detection is an internal ECU
threshold.
Check correct mounting of difference pressure
sensor at venturi tube
Exchange difference pressure sensor broken
Check cabling, if charge EGR Delta pressure
sensor is not working, check sensor and
if necessary replace it, check connection cable
and if necessary repair or replace it.
Check wiring harness and connected EGR.
Check cabling. If charge EGR Delta pressure
sensor is not working, check sensor and
if necessary replace it, check connection cable
and if necessary repair or replace it.
Threshold for error detection is an internal ECU
threshold.
EGR-Valve mechanically blocked open or
closed EGR-pipe blocked with metall plate
instead sealing downstream EGR-Valve
EGR-Valve actuator defect
EGR-cooler defect (check for coolant water)
Reed Valve defect
Intake throttle blocked in closed position =>
Check intake throttle
Exhaust pressure too high => Check Exhaust
pressure
Check Nox-sensor upstream SCR catalyst
dp venturi sensor defect
Exchange TEGR-sensor.
Check wiring harness to TEGR-sensor.
Exchange TEGR-sensor.
Threshold for error detection is an internal ECU
threshold.
There is no healing possible for the error. In
the every new initialization phase, the
debounce level is set to zero.
If not programmed, EEPROM is defect --> ECU
is defect, reprogram ECU and if
necessary replace it.
