I have a 1996 2.8 automatic Pajero with a problem. I have taken the car to
Main Mitsi dealer who has read the ECU and it gave these fault codes TC12
Boost Sensor and TC41 Throttle Control Valve. They could not help me any
further! I have disconnected / Blanked off the EGR Valve and I now have
full engine power. The problem is this. Always starts OK, when driving I
have an intermitant fault which the symptoms are: Feels like running out
of fuel / lack of power, yellow dash light comes on, black smoke from
exhaust, sometimes this clears in a few seconds and power comes back up to
100% yellow light stays on, other times engine stays running on low power
and black smoke? So far NO ONE IN THE UK HAS BEEN ABLE TO HELP ME!!! If
anyone can help diagnose the fault that would be great.. To me it seems
like a fuel or air mixture problem? Airflow meter has been mentioned but
how can it be tested? The injection pump is not electronic but is
manually operated with a traditional flexible cable... It will be
interesting to see if anyone has also had this problem around the world.
It is generally an excellent car and I have been very happy with it.
Ideally I would like to have it repaired as soon as possible but unless I
can get an idea of what is wrong it seems like no one in the UK can help!
Look forward to all the replies!!!! Thank you very much for reading and
helping.. Best regards

sensor. That is on the t-body. So is the TPS sensor. I have a feeling the
problem is there. If you see black smoke, that is too rich. The ECU is
probably getting a erroneous signal from the TPS or MAP.

hours whilst towing with no problem and then the next day the fault
happens, it makes no difference the speed or load that you are producing!
Thank you for your suggestion. I will now go back to the Main Mitsi
dealers who frankly have been expensive and have not helped much at all!
(I will never buy a car from them)
Re: PAJERO 2.8 LOSS OF POWER BLACK SMOKE Yellow dash light?
pocuk chat room and posted a request for help. It has so far been read by
over 165 people with not a single reply or suggestion.
Clearly the problem has to be with the fuel mixture but if the main Mitsi
dealer has no idea where do you turn? They just took £50 off me for
reading ECU and waved me off! I have been calling Colt HQ Uk and they
never call me back even when they promise to find out what the 2 fault
codes mean. Rubbish service and frankly this has really put me off buying
another Pajero!
Re: PAJERO 2.8 LOSS OF POWER BLACK SMOKE Yellow dash light?
the problem! If you want a job done do it yourself! I have solved the
problem myself and hope that this information will help other 2.8 ltr
pajero / Shogun owners....... THE PROBLEM WAS........... CRANKSHAFT PULLEY
AND CRANK SENSOR!!!!! The pulley is mounted in rubber and that gave way,
resulting in pulley wobble at low RPM and ok at high RPM centrifugal force
etc, the wobble damaged the sensor and that is why at low RPM I had the
black smoke and yellow light. I have today fitted new pulley, back plate
and sensor (don't ask cost of the parts!!!!!) but dealer did get them next
day for me and a bit of discount.. Now I have the fun of trying to get a
refund on all that labour charges and parts that I did not fit...
So now you all know.... She goes like a new car now!

Hi there, I live in new zealand and have exactly the same problem you
are describing with yours. I know this is a long time after you first
encountered the problem but i was wondering what you ended up doing to
remedy the problem?

Re: Mitsubishi Pajero 2.8 LOSS OF POWER BLACK SMOKE Yellow dash light?
I have a problem with a cold engine which dies after driving about 1 Km.
(Pajero 2,8TDi 1999)
I have discovered that pulling the handbrake, thus activating the warning
light, resolves this.
It takes a couple of seconds 5-10 after which the engine runs ok.
I have found this "workaround" while measuring, with a idle engine, to see
if the glowplugs are not stopping to soon.
(they did'nt)
The moment I wanted to drive away and thus pulling off the handbrake, the
idle speed dropped.
The idle speed went up again after pulling the handbrake.
Years ago I found out that the handbrake does something with a solenoid on
the fuelpump.
Let us know if it is the same with your car.

same problem you
Hi I have a 1996 Pajero 2.8 Diesel with the same
problem. What I have
done is to bypass the vacuum hose operated by the lowest
servo valve on
the firewall, this opens and closes the second servo operating a
butterfly valve on the intake hose.
The vehicle works perfectly now and has not
given any trouble. I am
not sure if the problem is with the vacuum line valve
that has been
bypassed or the computer that controls it. At first this did
concern
me, but the car goes great now, all the time, so why does it matter.
The vacuum is still connected to the end servo but now it stays open
all the
time. What was happening before is that this servo would close
like a choke on
a petrol engine etc you know the rest.
