Transit 2.2 dpf no regen

Post by busyguy147 »

Hello im new to diagnostics so any help with this problem will be great,i have a 2015 transit 2.2 rwd that has a problem to regen the DPF,the atomiser had failed and i have replaced that but still wont regen,i checked the fuse and swopped the relay under the bonnet in the fuse box,i got myself the obdlinkEX adaptor to use with forscan,i scanned the transit and found soot % is very high with fault codes,P244B,P246C,P24A4,P2463,all of them pointing towards a blocked DPF,i have been looking at the live data for what i can understand but now after a few more days or having to use the vehicle the dpf load in now above 300% ive had the exhaust temps above 200c but still cant do a static regen,1 of the things i dont understand is there is a reading that is EGT14 (bank 1 sensor 4) that stays at -40c but i cant find a 4th ex temp probe,im thinking it wont regen because of the high % and i may take it off at the weekend and maybe try to get it cleaned out,can anyone help me out with what to do next?

The best investment is a quality service manual and multimeter.

If there is no EGT14 connected - it doesn't exist and the data PID can be disregarded.
There are three that should be monitored.

Safe and simple testing is primary.
Don't do anything that resembles a knuckle dragging Neanderthal.

If asked in a Professional opinion and repair shop approach:

A) Disconnect the DPF assembly and send it out for cleaning, see point (1).
B) Photograph all three EGT sensors, note their positions.
C) With quality tools, remove them.
D) With a quality multimeter, carefully make a test harness to connect each EGT sensor and test the resistance.
Tests also include no shorting to earth (ground).
E) Mount each sensor in a vice and gently wave a propane torch across the sensor and measure the resistance changes.
The key words are “gently wave”.
F) If the resistance does not change, replace the EGT sensor. If shorted to earth (ground) then replace that sensor.

(1) I've personally seen the heating ovens designed specially for this type cleaning.
These ovens are specific and they are impressive but the smell and gases are a concern.
The other method is with high pressure washing systems that are the pulse type and they also work as expected.
The last method is a DIY chemical cleaning. Regard that as "maintenance" between regenerations especially if the Transit is only city driven and
doesn't see the high speed roadways. In that case, activate the regeneration cycle when the soot factor increases.

The theory is "regeneration takes place at highway speeds with distance, providing there are no faults recorded".

Reinstall all the original or replacement EGT sensors after the DPF is cleaned.

The main problems are the faults that need to be rectified if they are recorded again.

After all the repairs are completed:
You can begin to rectify part of this problem by resetting the DPF learning values.
Start the regeneration again.
If there are faults, the regeneration will not continue.

Post your results

Thanks for the info,im going to have another look at the transit at the weekend,first thing im going to do is take the exhaust off and them the DPF and get it cleaned out,will do the checks on the 3 temp sensors,after that will see what happens and report back here.
