Car Forum / Mitsubishi Cars / August 2004PAJERO 2.8 LOSS OF POWER BLACK SMOKE Yellow dash light?
Hello 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 blue-python UK Is this a turbo vehicle? If not, the boost sensor is probably really a MAP 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.

Best regards > blue-python UK Yes it is a turbo 2.8 ltr and the problem is intermitant. You can drive for 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) You may want to check the owner forums at www.pocuk.com . POCUK is the Pajero Owners Club UK. Someone there should be able to help. Thank you but so far no one at pocuk has any idea! I have been on several 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! Hi, I cannot find your post on POCUK forum? can you post a link to it as I have a similar problem with my Mitsubishi Delica 2.5TD > Thank you but so far no one at pocuk has any idea!

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! Cheerio blue-python Hi Blue Do you mind if I do ask the cost of the parts? and how easy was they to fit? I don't have the problem now, but you never know ay?
