Avensis d4d P062D blue smoke diesel knock

Recommended Posts

This is regarding a Avensis 2.0 d4d 2011. 180k.

P062D code appeared with engine knocking.

I have found a TSB with this code thanks to @DevonAygo

EG-0024T-0212
Subject: Loss of engine power and MIL ON due to fuel injector failure - DTC P062D MIL ON
Models: AURIS; AVENSIS; COROLLA; RAV4; TOYOTA RAV4; VERSO
Model codes: ADE150; ADE157; ADE186; ADT270; ADT271; ADE150; ALA40; ALA41; ALA49; ALA30; ALA35; AUR20; AUR21
DESCRIPTION OF PHENOMENON Some customers may complain about injector failure causing a loss of engine power and MIL ON. DTC P062D (fuel injector driver circuit performance) is stored in the memory of the engine ECU.
PRODUCTION CHANGE The production process of the fuel injectors has been improved.
Injector feed backs need to be monitored via diagnostic PC if feedback volume of 1 or more injector is greater than +/- 3.0mm replace faulty injector/s with modified injector, if feedback of all injectors are < 3.0 mm Replace ALL injectors with modified injector

Number one was replaced with a brand new denso one but after a few days the fault returned. 

All injectors have been removed and tested by a diesel company and dpf checked by dpf specialist.

So after it being in local garages, it went into Toyota yesterday who have advised to replace other 3. Its the first time I have had to replace all 4. How have all 4 injectors gone at the same time plus how can a diesel company who have bench tested them say they are fine but Toyota say to replace. I am desperate to get car back on the road as its a Taxi. 

Toyota have advised once all injectors are in you have to code them in and then learn them the new values.

So another 3 will be going in followed by coding them in and learning them the new values. 

Weird thing is. Car is fine when cold as soon as it warms starts shotting smoke out and knocking. 

Toyota advised the inlet mannifold is coked up too. So that will be cleaned.

Will update this thread to help others in future.

Hi I. 

The question regarding the diesel company testing the injectors as good, could be down to what data they compared to, and is that data correct! Toyota will have more detailed information on your engine, so be able to figure out the injector specs. Plus someone commented in another post to change all the injectors, not just the faulty one. This balances the whole system. When funds are short, then one would have to make do, but the fault may return. 

Also has the wiring to the injectors been checked! It may explain why the diesel company said the injectors are fine. An auto electrician may back probe the connectors to check the current and signals are getting through. A replacement injector won't fix the problem, if there is a wiring issue! I assume this has been checked. 

Hopefully everything above has been done and Toyota are dealing with this. I have been watching a few diagnostic YouTubers, and they all seem to to follow a logical approach. Not seen one with your particular engine yet. 

Good luck and keep us posted. 👍

So now all 4 injectors have been replaced by denso ones. P062D code has cleared. 

Car is driving back to normal BUT there is smoke not clouds of it as it was before, it happens when setting off in 1st at a junction or putting foot down in 3rd.

Inlet manifold cleaned as was very coked up with soot. Still blue smoke. 

Anyone else experienced this?

I have a different problem, as soon as the car reaches operating temperature it suddenly emits blue smoke. When the operating temperature is reached and the thermostat is opened, the blue smoke is lost. I handle this with a stop leak from Liqui Moly

Very strange. I think next car will be a hybrid or petrol.

If you get a hybrid, make sure if the car is an Auris or Prius, you get some form of shield to protect or at least slow or deter thieves! Hopefully it's not happening in your area. My mate Waqar was unfortunate to be a victim - 

He is now has a shield  installed as shown in the photo. 
For now 'I', you are better off getting your diesel sorted. At least you are not in an area affected by penalties on diesel, yet!
