Power
reduction:
engine
rpm
drop to idling
speed.
Press brake and
accelerator
at
the same time.
Check wiring and
connections.
Replace sensor if
required.
If the brake is
actuated
while
the accelerator is
pressed,
the
motor runs on
slow idling until
the
brake
is
released, so that
the vehicle can
be stopped even
if the pedal of the
accelerator
remains stuck on
the intermediate
position. Instead
you
can
accelerate while
the
pedal
is
pressed without
the interference
of
safety
measures.

Emissions
not
compliant with
law.
Derated

and smoke at
high engine rpm.
EGR
monitoring:
incorrect
EGR
percentage
actuation
calculated
by
ECU.
Check, if the EGR
pneumatic valve is
not locked in Open
or
Closed-Position
2) Check, that the
solenoid valve and
the EGR pneumatic
valve is not squashed
or holed or detached
3) Check the EGR
solenoid
valve-functionality
4)
Check
the
solenoid
valve-integrity
by
means
of
a
multimeter
5) Check the wiring
harness between the
solenoid valve and
the EDC connector.
