Fantastic video, everything explained so clearly, i lreally learned alot from this thank you for all your time and efforts , very much appreciated
Thanks for watching and for your comment
Awesome video SY, keep them coming
excellent video.very professional work.bravo!!!
Great video as always well informative
Nice work Steve, very informative breakdown of the system. 👍🏻
Cheers Dave, thanks for your support
Epic content thanks for sharing.
Great video, used this to fix my Focus
Another brilliant vid from SY. I have gained so much by watching your videos mate especially being out of the trade for so long. I feel like I'm keeping my toe in with CPD. Keep up the good work Steve
Great content as always . Nice one !!
Great knowledge, I watch all your videos
thanks
Some brilliant information. A lot of effort went into this video
Thanks
Absolutely Great. Thank you.
Excellent video. Much obliged.
awesome and explicit
Great test and explanation as always, thank you for all your efforts. I tried a clean on my own car using intake cleaner then ultra sonic injector cleaner just as an experiment. Been ok for a good while now and have done a couple more since. Only really an option if budget is super tight.
Brilliant video..thank you for sharing..
Glad you enjoyed it
Awesome as ever
Great info
That's a great brake down of the Dpf systems and the vaporizer well done and thanks for sharing.
Thanks for watching and for your comment
Excellent video as always, I’ve got a Mondeo in at the moment for exactly this problem, I thought the fuel pump must be PWM controlled but couldn’t find a diagram to confirm. Also worth noting the fuel pump won’t activate with the scanner (snap on solus) if the fault codes haven’t been cleared sending me on a wild goose chase, I don’t know if Forscan is the same? Keep up the good work Steve
Thankyou 👍
Hi, really enjoyed this video. It's a pleasure to watch a really competent mechanic. The way you explain things is so easy to follow, and how you check components with everyday tools like an amp clamp that any good home mechanic should have access to. Quick question, I have a Mk4 Mondeo with 100k miles. Been an excellent car, now thinking of changing, is the Mk5 just as good, or should I look for another Ford model?
Thanks for watching and for your kind words. Regarding the Mondeo Mk5, I seldom see issues with them. The occasional BCM or steering lock or parking sensor issues is all I've seen myself

And if you are really tight like me, a great way to unblock the vaporizer is put a 3" section of bicycle brake cable in a drill from the exhaust side of the sensor works a treats long as the glow plug tests ok.
very very helpful video I like it twice then I see that the second like is a dislike so I like it again
Ha ha....thanks
Great video. Loads learnt thank you! Can I ask a question? How does the van monitor oil quality? Is it a ECU calculation from regen data? Or can it actually “see” the oil condition?
On the delphi system, a strategy has been implemented within the PCM to detect oil deterioration. Frequent short journeys require all available measures to increase exhaust gas temps to initiate a regeneration, which include post injection, also regeneration intervals are shorter too. A strategy is used to calculate oil quality based upon the measures taken to increase the temperatures and when the threshold is reached the warning is shown. So, yes its a calculation and not a physical measurement as such. In other systems and manufacturers it may well differ.
Thanks for the reply SY.
The reason I asked is My vans (euro 5 and euro 6) both do relatively short journeys, I like to change the oil more frequently and assumed I would still get the “oil change required” message from time to time. Because as you say it doesn’t know I have changed the oil.
Hey, thanks for the great video! If ever you have time to answer a question, I would greatly appreciate it…
P26A0, I’ve done lots of diagnosing and the glow plug seems to work except when it attempts a regen (then the 20a fuse blows and the vaporizer/dpf overheat).
My investigation led me to believe that the fuel pump isn’t providing fuel to the vaporizer which causes the overheating. There are no other codes and the van drives great (no loss of power, no black smoke, etc…)
What do you think?
To blow the 20a fuse I'd being checking the current draw of the glow plug and/or checking that the harness fir its supy is not shorting go ground. Usually without the glow plug working the temperatures aren't reached and flag a code for conditions not met.
Thank you so much for taking the time to reply! I will add these steps to my tests.@@SYDiagnostics
Excellent and very informative video. I changed mine 2 years ago and everything was fine but now it only reaches 520 Celsius on active regeneration and stops with P244c, temperature too low. Cannot reach over 600. Did you encounter something like this ?
I have tgus problem now ...have you fixed the problem?
@@pkae85 nope, same behaviour. Don't know what to do with it.
great video - in your time working on these have you ever come across a P20CD code (low voltage to exhause aftertreatment control circuit)? I've been testing pretty much all the wires, can't find any issues in them and its driving me crazy (I'm down south or I'd pop it in to you)
ive seen similar codes on euro 6 transits and its been the alternator
Excellent video! I have a question, I would really appreciate it if you could help me! I took out my vaporizer candle, disassembled it and washed it (would it damage it?)... but I took the opportunity to test the candle by connecting the battery's positive and negative for a few seconds... I noticed that it takes a while to heat up and even leaving it for a few seconds. After 10 seconds it heats up, but does not become incandescent. Would this be a defect? One last question, is it possible to change just the spark plug without having to change the body around it?
Thank you very much!

It sounds to me that the glow plug is poor. I've never removed one to test its heat up time, but a conventional glow plug would glow fairly quickly. To my knowledge the vaporizer glow plug isn't available on its own. I'd suggest a new vaporizer and check the fuses
Thank you very much!
Very good. Çok güzel web sitesi. Türkçe versiyonu var mı?
I wasn't aware the system was as complex.

Great video, would a bad vaporizer cause a 2014 ford kuga 2.0 tdci to give out black smoke under acceleration even after a new dpf has been fitted a year ago?
I doubt it. The vaporizer is only fitted to aid raising the temperature of the dpf in order to regenerate. I'd be looking at possible boost leaks / restricted air before moving on
Hello i have a focus mk3 2013 with 1.6 tdci econetic and the dpf pressure si from 0.3kpa to 1.3 when its regenerating
Is ok ?
How can i test my fuel pump?

Can the glow plug be replaced instead of the whole vapourizer. Thanks.
Great video! Quick question though. What is the proper spray pattern from the vaporizer? Does it actually create a vapor of diesel fuel much like a typical fuel injector? I have one that will not do a manual regen. I removed the vaporizer and actuated with the scan tool. The fuel just dribbles from the hole. There are no visible obstructions. Seems like it should be more of a spray pattern.
it sprays onto the glow plug within the vaporizer rather than into the exhaust. It appears to be a dribble when activated. Is your glow plug in the vaporizer ok and its supply?
Have removed my vaporizer to measure the glow plug is at 1.2 Ohm (0.2 Ohm indicates that meter itself) is that okay?
Hi, I would like to know where you get the manual that shows in the video
its all from various sources, which point in particular
the dpf system point because not much information in our country
Do these have a replacement interval?
no they dont
Great Video! Question? I got a code P244C no limp mode, soot load %184 DPF load %40. Is it possible faulty glow plug or partially blocked vaporiser ? Tried static regen always failed with this code. Pls help. Thanks
definitely i'd be checking the vaporizer and its glow plug and fuses
@@SYDiagnostics Thanks for the reply, its so hard to remove the vaporiser lol, But will try to remove it and update you. Thanks
@@SYDiagnostics Also what is the size of the spanner you used to take it out?

i dont supose you live near manchester do you my ford transit minibus has codes p2463 and p246c dont really want to take it to a garage incase they dont know what they are doing please help
Im not near Manchester but for DPF issues, I'd recommend looking at the DPF Doctor website and find you nearest specialist, they are all good. You can mention me as i know most of them around the country
Hi Steve. Is it normal for Transits to produce white smoke when they're doing a normal active regen while driving?
Only time I've seen white smoke was when a non genuine dpf was fitted and the heat couldn't be generated sufficient to start thd regen process (prior to vaporizer starting) or when the vaporizer fuses have blown dud to failed glow plug, but this usually generates an insufficient exhaust temp code.
Thanks for taking the time to reply. DPF is original on this one, vaporiser is clear and I can see it heating with a thermal imager so not sure why this one is smoking? I’ll try to monitor the temps. while it’s doing it.
mine is blocked and i cant get it out the dpf
Hi I have after treatment glow plug circuit high and p2002 dpf bank 1 threshold efficiency low. Would this be vapouriser fault ? Thanks
the after treatment glow plug would be the vaporiser glow plug, but check the fuses too. P2002 could be a faulty pressure sensor or a faulty dpf (cracked, holed)
@@SYDiagnostics that’s great thanks for your help. Would vapouriser cause both codes usually ?
@@jay-pp4096 no, both separate issues
@@SYDiagnostics thanks for your help
Nice article, but the temperature reading is a little higher for regeneration. normally 550 deg C and above to begin the process, 450 deg if the system employs the additive fluid employed in the PSA vehicles. This fluid added to the diesel automatically during refueling lowering the temperature which carbon is burnt off.
regularly seeing 620 - 640 on static and driven regens once in full flow, but its difficult to be anything but approx. when doing these videos, hence i always state approx. values. I realise I have made an error in the video where I should have stated a minimum egt of 350 c is required in order for the vaporized fuel to react in the oxy cat. Thanks for alerting me.

impossible to get to !!
Are you a ford mechanic?
Common fault. Also if it keeps blowing the 20a fuse it needs replaced I hate them
Dead common issue, no drama, move on
Yawn !! fix or repair daily (FORD)
