Possible cause of fault Possible effects
Fault remedy
No signal
◆
Open circuit or line
short-circuit
◆
-G70- defective
◆
EGR is switched off.
Diesel particulate filter
regeneration sup-
pressed
◆
Driving dynamics not
or barely impaired,
because a good alter-
native value is used.
Possible breakdown
due to full DPF (con-
sequential fault)
– -G70- Check.
– Check whether there
is an electrical fault in
wire or wiring harness
(short to positive or to
earth, or open circuit).
If not
⇒
renew sensor
– After road test fault in
event memory
⇒
re-
new ECU (there is no
other way to test the
air mass meter,
maybe with a frequen-
cy generator)
00273/P0111
Intake air temperature
sender -G42-
Implausible signal
◆
Open circuit or line
short-circuit
◆
-G42- defective
◆
No limitation
– Check intake air tem-
perature sender -G42-
– Comparison of all
temperatures with
completely cooled
down engine and ter-
minal 15 ON / engine
OFF
– Electrical check of
sensor wires. Possibly
auxiliary heater coded
incorrectly
00274/P0112
Intake air temperature
sender -G42-
Signal too low
◆
Wiring open circuit or
wiring short to posi-
tive
◆
-G42- defective
◆
Torque limiting; diesel
particulate filter is
locked
– -G42- Check.
– Pull off temperature

⇒
sensor de-
fective, sensor raw

value block approx.
0 V
⇒
check wire to
ECU
– Wire to ECU OK, ECU
