Hi,

I purchased toyota techstream a while ago through ebay in order to do my own DPF Regeneration.

Recently i managed to get connected to the vehicle and could read all the data etc. However when i went to do a regeneration the option came up to enable it, and when i clicked this although it changed to say "Yes" for regeneration the car actually did nothing?

 

Can anyone help or explain what Im doing wrong?

Have you got the engine running and up to temperature?

Hi John, 

 

Yes up to temperature and running, I run the test and watch the RPM's and they don't change.

Is the engine management light on? (It must not be on)

Is the EGR valve operating correctly and not blocked? (It must be operating correctly)

Is there at least 20 litres of fuel in the tank? (there must be at least this amount)

The DPF will not regenerate if any of those are not correct.

Does it actually need to regenerate at the moment? I suspect nothing will happen if it doesn't.

John,

EGR Valve is opening and closing (tested using Techstream)

The fueling could of been the issue? I will top that up!

Well as far as I know it does, I don't have an DPF Error on the dash, however, it smokes constantly! I wanted to try a regeneration before purchasing a 5th injector and trying other routes.

Also - I have once tried and failed with replacing the DPF, the one I bought was the wrong one for the car and so the old one went back on! when i looked inside the old one some of the material was a little bit broken?

thank you for your help!

Blank of the pressure sensors, go for a long run and activate the regen.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
