HELP!!! My innova D4D Black smoke- pls Help!!!

[emptytank]

Hi, i've been searching the whole forum on Innova Black smoke and it seems that we have not found the solution.

I have the same problem with my 2008 D4d Innova matic, 20,000km the engine is perfect, (just remove the black smoke).

It starts to emit black smoke at 1500 to 1700 rpm while running. when i step on it some more.. naturally it becomes a thick black smoke.

How do we correct this?? I already changed the oil, oil filter, fuel filter, air filter and i used original toyota filters. As for the oil, i used the petron trekker oil and it is still the same. I also had it checked with the computer testing of a reputable shop. they plugged in their computer into the port on the drivers side.. The testing said my engine is perfect and ok.. wierd...

Help Help....before my car gets impounded for violation of environmental laws.

How about the injection pump . Na pa calibrate mo na ba magmula ng nakuha mo ang sasakyan.

Thanks for the advice speed unlimited.

Hindi ko pa na pa calibrate yung injection pump. I was thinking parang medyo bata pa yung sasakyan for that may power naman ang car? Or is this a factory defect?

If ever do you know of a good place to calibrate the injection pump for the Innova Diesel? Mga magkano kaya papatak ang calibration?

Thanks

Consult mo si Dieseldude, threadstarter sya ng Diesel Engine Fuel Injection System Helpdesk. He knows a thing or two about the D4D issues.

Just wanted to share how i was able to solve the problem. I started reading about EGR problems on diesel engines and problems encountered by other innova 2kd-ftv owners. Then, i got a little idea on how much i should spend to fix this dam car. About 100,000 Pesos daw to replace those common rail, injection pump, turbo, Egr (as for what other Tsikoteers spent on repairing the innova) I was problematic since i still have to pay for the future installments of this vehicle and i can't afford another 100k for repair.

So after analyzing the engine, i decided to do an experiment. I removed the vacum hose that goes to the EGR and drove it the next two days. Bingo, 80% improvement on black smoke emisions. Literally the black smoke is almost gone. It only comes out now when the RPM hits 3,500 (minimal black smoke). When i connected the vacum hose back to the EGR, it was back to the same problem (black smoke at 1,500 rpm). I can say that the EGR is actually causing the Emission of Carbon. A bonus is there is about a 10% IMPROVEMENT on the acceleration of the car.

The "bring to Dealer" light went on but it eventually went off after a day. Who really cares as long as it does not emit black smoke. Now, by removing the Vacum hose on the EGR will it bring any ill effect on the engine of my vehicle?

Any idea?

Greetings. Just wanted to share that 2 years ago, my company gave me an E Variant Innova A/T. After 7,000 kms, it started smoke belching upon accelaration. Toyota Pasong Tamo had me practically living in the dealership for 2 months and I didn't get any work done. This is the list of what they did based on what I remember over span of several months:

1.Changed Turbo Charger
2.Changed EGR
3.Cleaned exhaust pipe several times
4.Tested Diesel Fuel
5.Reprogrammed Computer
6.Changed Injectors

None of these things solved the problem permanently and I have the unit back to the company. Toyota Pasong Tamo steadfastly refused to change the unit and just kept wasting everyone's time repairing it.

I hope no one ever goes thru what I went thru. I'll never buy a Toyota again!! Di tama yung ginawa nila....

Thanks for reading this friends.

good morning tsikoteers...i stumbled upon this thread because i am an 2010 innova J D4D owner (the v-shaped grille) and a newbie on this forum as well.

My unit already has 18k KMS (yup, hindi siya masyado ginagamit) on it since we bought it last december 2009 (was already considered a 2010 model) and it seems that Toyota has already rectified/corrected the problem. I have no black smoke upon cold start, acceleration (kung aabot sa 3+k RPM, may katiting na usok but not black.) and power is great.

Ask ko lang, is it true that they already fixed the flaw (that they don't want to admit na it's a flaw) with the D4D system on 2009-2012 Innovas and other toyota vehicles powered by the same Toyota KD engine?

And another question, does the innova use a Diesel Particulate Filter (DPF)? Or puro catalytic converters lang siya? kasi EURO II compliant daw ang 2KD-FTV...
