How To Diagnose A DPF Diesel Particulate Filter Differential Pressure Sensor & Test Hose Pipes

Автокөліктер мен көлік құралдары

here we have a vehicle where two people have tried to do DPF cleaning to resolve a flashing glow plug problem and DPF Fault codes
blocked DPF pressure hoses that lead to the differential pressure sensor tubes was the primary cause of the fault
tools used were...
Autool digital manometer
mityvac pressure tester gauge
Autel MK906BT
plumbers blowtorch

    Another billiant video. No waffle, solid explanations of the 'what' and 'why. Surely the best YT channel for DPF related issues?

    Love your videos and help you give in the videos I’ve been watching I’ve watching them for sometime now I have a 2006 be crafter that has had a number of issues I’ve been working on related to the DPF and it seems almost every vehicle fitted with one has issues with them at some point ! Do you think it’s time the manufacturers Do a recall on them and offer a better usable solution! To the problem Big thanks kev

    There was dead tube (just ruined into small pieces :) ) on renault laguna III, after DPF. Replaced to another 6mm for fuel, but error still exists and see that diff. pressure is 0 or -1. Will check if not blocked tube (metal) to DPF or if sensor reacts to pressure in rubber tube from that join. The amount of ash in dpf renault canclip shows about 27grams, have to hurry up :)

    can you give me an idea what to check? I checked the hoses, replaced the pressure sensor to be sure is ok, seems fine, I got a value ~7mbar at idle and ~20mbar @ 3000rpm. What I dont get it, is why is regenerating if DPF is clean (I also take it out and give it a deep clean even before cleaning was not clogged and was regenerating ~ every 50 km and then reprogram as I have change it), and acc. calculation it is showed ~40% normal clogging. I is normal to regenerate often (500km interval in city conditions) even if is not clogged?

    Hi Jimmy, I have an issue with my vauxhall zafria b where it keeps stalling when idle (after 10-30 seconds) and whilst slowing down to stop it will cut out unless i keep the revs up higher than 1k. I have been told its my DPF and needs replacing. Its currently at 96% saturation but when i just connected it to opcom the DPF sensor doesnt seem to be moving up very much. Could it be just blocked pipes rather than having to replace the DPF? 😮 Cheers

    Ah mate can’t remember properly. Pretty sure was a code for implausibility signal for dpf sensor. Eml was on and think in limp mode. Wiring was all good. New genuine sensor sorted it. Sorry for the vagueness 😂.

    Great video. By the way, what pressure side this sensor reads, upstream or downstream?

  • @madds6678

    @madds6678

    Жыл бұрын

    It’d be upstream checking pressure build up in front of the dpf. Most modern cars have a differential pressure sensor that checks before & after (as in the word differential), older simpler systems just have a pressure sensor in front.

    Hi, take the pipes off so sensor is at atmospheric pressure ie zero and see what it says then, if still 1 or 2 then sensor could be faulty or just needs calibration
