I have a dpf issue with a ford transit connect 2012
eml on - code relating to DPF Soot accumulation.
there no codes for temperature low during regeneration.
i have replaced the dpf and pressure sensor but light still comes back on after a very short while.
i have a 5v ref and earth at the multi plug. our tool is only reading the differential pressure in psi
what i am finding hard to find is what reading i should get on idle and with revs.
would anybody be able to help with what is an acceptable level of a good working dpf system. and at what levels should bring on the eml on.
any help would be greatly appreciated.
The engine runs perfectly fine, and doesn’t excessively smoke,knock and no other error codes.
I would like to have seen more obvious signs if the engine was worn,
With that in mind I’m just trying to understand what readings my pressure sensor should be reading as a good base values.
At idle servicable dpf around 0.5 to 0.6v
At 2000 rpm if your seeing 0.8 it is loaded but requires regen
If over 1 volt it will log the soot accumulation dtc with different failure mode and status this impeads drive to regen and service regen.
If you want a matrix for the sensor I have it voltage vs pressure just pm your email
