Hi all,
I have a RAV4 III 2.2 D4D automatic transmission.
I got the error P2002 and the car went in fail safe. One month ago I had had same problem and I had cleaned the DPF with a chemical bath. Obviously that work wasn’t so useful. My first problem now is that I am on holiday 500km far from home and any good garage. Is there any way to reset the failsafe until home? I tried many times with my OBDII device but the error came back instantly and the car fall again in failsafe. Is there any trick to unlock the failsafe?
Then I would like to know if anybody tried to regenerate the DPF by using a thermal treatment with special oven. Could that be more effective?
Thank you

:welcome: to the club.
What year is your RAV?
If you fill in your full vehicle details it will help those who may be able to advise.
Others will be along with advice regarding DPF but I'm wondering if your problem may be related to the EGR?

I blamed the DPF because I recentely started using the car for very short trip and then the P2002 if I am not mistaken talks about a pressure difference... Anyway at the moment I would like to get home easily if there is any way. A trip in failsafe on a motorway is pain! Thanks |

Well that’s a first. A 150 with a blocked DPF.
I doubt very much there is anything you can do because if an acid bath didn’t fix it and you are still struggling, it sounds like it really is blocked. You might try staying away from supermarket diesel and be sure to use only low ash oil. Out of interest, has it been regularly serviced?
I think you’ll end up getting that DPF changed so you might have to negotiate a good price.

Yes it has serviced regularly. I should bring the car to the garage for the 120.000 Km service in the next weeks. I had a problem with the injectors at 100.000 Km but Toyota replaced them all in "good will" I read somewhere that if I witch the car on/off for 5 times the failsafe mode should be reset. Have you ever heard something like that? |

I heard it too but maybe 10 times. I’m immediately suspicious about the injector change. Why was it done?

At the beginning an official Toyota garage proposed to replace all 4 injectors for more then 1.200 Euros. I looked into the problem and first of all I discovered that I could change just the defective one for more or less 400 euros then I read that many other RAV4 suffered the same problem so I wrote to Toyota to ask why an official service point asked me to replace 4 injectors when just only one looked to be faulty. I am bound to say that they were very kind proposing to replace all the 4 injectors for free. Nobody explained me why the injectors were replaced unless doing general suppositions inlcuded that Denso piezoelectric injectors do not work fine at all.

Faulty injectors are not unheard of but they certainly aren’t common. The point is that a faulty injector might well contribute to a blocked DPF and you might get somewhere with a policy warranty claim. A lot depends on where you intend getting it repaired.

The point is that a faulty injector might well contribute to a blocked DPF and you might get somewhere with a policy warranty claim. A lot depends on where you intend getting it repaired. Unfortunately warranty was already expired. Toyota decided to replace the injectors at their own cost. Today I drove for 20 Km (20 minutes) then I switched off the car. Then I drove againgf or 5 Km and I parked. It was still in failsafe mode. Then I come back and magically it was no longer in failsafe. I didn't reset any error end LCD showed the problem but the car ran regularly. It happened even when I brought the first time the car to have the DPF cleaned with chemical spry. I cannot figure out why now it looks to work fine despite the amber Xmast tree on my dashboard.
You could be right: a defective injector could have helped to stuck the DPF. When I come back home maybe could be usefull a deep cleaning of the DPF and EGR but I still haven't no ieda if it is better using chemicals or high temperature oven to best cleaning the filter.
