Power loss and black smoke kia sedona 2002 diesel

I have a power loss with my kia sedona 2.9crdi. when pulling away in 1st gear it has a lot of black smoke out of the exhaust. it is slightly worse when the engine is cold .i have changed the fuel filter, checked the egr valve, the turbo has been checked (although it seems to have lost its "whistle"),The air mass flow meter has been changed.Air cooler is ok.It has blocked/ choked the cat with dust but i have removed this from the system whilst trying to find the cause.I dont think it is the injectors as it is an intermittant fault.It has been on a kia diagnostic machine showing no electric faults. and i have also been in the fuel tank looking for filings but it was clean.Do you have any ideas what to check next and does it have and electric fuel pump? if not how does it maintain the fuel pressure for the common rail?

SOURCE: I need to locate the common rail diesel sensor

there is a sensor fitted to the commen rail itself.. you have to remove all the black plastic and the intercooler from the top of the engine to get to it

SOURCE: kia sedona 2.9 diesel 2004 have had fault codes checked by kia dealer they tell me it is the air mass flow meter code that has come up have tried two new ones exactly the same

check the air intake hose for cracks between MAF sensor and the intake. very common to crack underneath and cause the engine to set various engine codes.

I have a 2005 KIA sedona. And when driving it sounds like it has a turbo. It also has no umph.instead it loses power going up hill. while the turbo sound it hesitate to shift gear.


Yours should be a 2.9 crd Turbo diesel if I'm correct & from what your describing sounds like you need to change out the diesel filter. These filters get clogged causing lack of power specially going up hill.
Is it blowing out black smoke? There could be other problems as well. Need more info like is the engine light on?

2012 kia sedona white smoke comes out of exhast when first started


White smoke is usually an indication of burning antifreeze and burning oil would have a more bluish tint to it and smell like burning oil. If it's a 2012, isn't it still covered by the KIA warranty though??

My 3rd gear started grinding then 2nd and 1st, how do I check if its the hydraulics for kia sedona 2002, or does the clutch ned replacing?


Are you losing any fluid at the reservoir? Either way Its probably the hydraulics. normally if the mechanical units(pressure and clutch plate) were to fail, there would be immediate loss of clutch on all gears.I'm a little surprised that 1st gear didn't start grinding before the others though since pumping the clutch would build up abit of pressure in the system. Start by examining the bores of the clutch master and slave cylinder for scouring. If they're ok then replace the rubber seals(a.k.a kits in some parts) and bleed the system. Its certainly a cheaper, time saving first option before then attempting the mechanicals.

How I can decrease the smoke belching of my KIA Carnival Sedona diesel 2002 model?


change the air filter usually works a treat. if not get some of he de-coking fluid to add to your fuel. u can gat it in most motor factors for a low cost and this also helps your engine immensly. if it neither of these work let me know and we can go further but it usually gets more expensive after this

Driver side 2nd row seat is stuck in my 2002 kia sedona


I have had a similar problem. I solved it by keping the seat back raised, get someone to rock the seat back violently while you pull on the balck strap and try and remove the seat. This may not happen 1st time if not spray WD40, and lots of it all over the seat linkages and locking mechanism under the seat.

When you get the seat out turn it upside down and spray with WD40, do this with all the other emovable seats.
