ACCELERATOR
PEDAL/BRAKE
PEDAL SUSPECT

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.

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.
