I have a 2013 Transit Connect, which has recently developed a rough idle and engine hesitation, so I put my OBD reader on. Came up with a big red X against EGR valve. Not going to mess about cleaning something that has done 120,000 miles. I've picked up a genuine motorcraft replacement on Amazon, and ordered a new gasket all for less than 85 bucks. My local Ford garage was very helpful making sure I had ordered the right part number as per my VIN, but they couldn't match the Amazon price, even at trade. I had already decided I was going to tackle it myself, being an ex-mechanic, although not for the past 30 years, but I figured it was still within my skillset, and of course I have the bonus of all the tools I will need. Your vid pretty much confirmed what I had already mentally worked out as my best approach, so a big thanks for that. Your vid is excellently filmed, with a great explanatory commentary, so I am now well prepared. I'll be tackling this at the weekend, and I'll let you know how it went. Thanks again for taking the time to upload such a helpful video.
I have the same model Ford Transit connect 2013 and i replaced the EGR valve but i still have a problem with this.I connect the OBD scaner and the EGR sensor never stop yo flashing
I'm actually gonna take it off today, and just replace with a new one just because it's so hard to take off and put back on and don't want to do that twice!! The other problem can be the electrical component on the top with the 4 screws that can be defective not doing it's job pushing the plunger. I bought mine at a local Napa store which cost $81.00, when all the other big box stores wanted anywhere from $180-$240!! Napa is usually More expensive, I was surprised!. I will update after I do this! Thank You for this very well informative video Gerald!! Any other comments you may have from this comment, please reply. Thanks!
Mate!!!!1 you are a total diamond, was quoted to change the egr for an arm and a leg, but after watching your video i took the top of the egr off and used a little penetrating oil while giving the valve a good move. Eml never come back and all is running fine 3 months later.
thank you very much friend. I replaced the EGR valve with a new one and the problem continued. Thanks to you I cleaned the old valve and installed it again and I haven't had any more problems. I have driven my car for 3,508 miles and have had no problems.
Nothing worse than a broken new part.
Thank you so much for share this guided, My Focus mk2 is also experiencing the P0400 code, This video gave me some clues on how to repair my EGR valve. Excellent!!
Unreal video Gerard, I enjoyed watching the full process. Top technician at work 🔧 keep the videos comin!
Thanks very much for the kind words

Thank you very much for this video! I'm getting ready to pull egr off 2010 Ford escape, and now i know what to look for!
👌👍💪
Fantastic job of explananing! Thank you!
Wobble joint is hard to purchass locally, best I could obtain was a "universal joint" adapter, thanks for this video 👍
Been looking for this for months, thank you! I have an 08 Escape 2.3L w/ the same EGR setup.
Thanks Hudson
Excellent video. Thank you.
Thanks Gerard. This was a very instructive video. Now I know what to look for if my EGR valve is acting up.
Thanks for the kind words 👍
Very helpful thanks!
Excellent!! My engine, my problem exactly.
Would you know why my instrument panel display keeps cycling through all items... odo, trip, miles remaining etc?
Thanks triniad
Gracias man
Many thanks, this is what I am looking for. But can you also show how to remove air cleaner box, please?
Did you drain the cooling system first? If not then roughly how much coolant leaked out please? Thanks 😕
Hi thanks for your very informative video . Would you suggest anything for me on my returning p0400 code. I got 2007 focus . I have replaced egr valve and vacuum solenoid but still popping up engine light once i drive 5 to 10km after code is cleared. Never had any symptoms even before parts were replaced. I went to mechanic and auto electrician they didnt seem to know much. Thanks
Great job Gerard:):)
Thanks Pat 😊
Thanks for this Gerard. I was having trouble finding videos that help a MK2.5 Focus but this is the closest to mine.
I tried this earlier but my socket set is too thick to get in under the hose to undo the rear (as you look at it) bolt. If you could recommend any thinner ones, like the ones you have, that'd be helpful.
Thanks again
He used quarter inch drive that’s a tiny ratchet and because the tight only have to be tight enough to seal out air they don’t need to be that tight
Where do you get wiring diagrams. I'm looking for a Ford focus 2007 and 2008 for oxygen sensor.
Oh man, I think this is exactly what we need to do to my husband's car. We are millennial wannabe farmers and don't have enough money to pay someone else to do this. I am NOT looking forward to needing to take all that other stuff out of the way. :( Anyway, thank you so much for the extremely thorough video!
First time I see a disassembled EGR valve.
Pretty cool :)
Anyone know what will happen for the upper part(black motor or solenoid)if I separate it form bottom part but still connect to the ecu? Will the motor breaks down because without load form botton? I'm trying to remove the EGR function but don't want the fault code to pop up. I'm wondering if just to separate them will work.
Hi Gerrard
So both centre pins 12v
How can you activate it off the car!
Very good job :)
I did that cleaning job to my Ford focus flexifuel 1.8 L ...with the result of getting an fault code P0403...im going to check if it is a problem with the wires or if the stepper motor is dead today (2020-01-11) so frustrating....And i can´t find a wiring diagram for that engine model...weird ??
Let me know once you find a wiring diagram for this engine :-) Cheers
I had a P0403 fault code on my Focus,it had a break in the wire going into the multi plug for the EGR Valve,fixed that,put new valve in,now ended up after a while with a P0400 Code,so going to take the valve off and clean everything
Thanks for the video Gerard. Just a question about the coolant - did you clamp off the line to prevent losing coolant does it flow from/to a port in the engine? How much do you think comes out? Cheers
Yellow clamp seen at 12:24, vacuum in cooling system should help reduce amount if no clamp is used, top up as necessary 👍
A very useful and informative video! Thank you for taking the time and effort to make this. At 12:10 "THis" is in the way what is that, and can i remove that to easier remove that bolt i might round mine :(
Thanks very much. yes you can remove that, it is a much better idea to remove it rather than damage a bolt trying to avoid it. Good luck with the job
Weird that there's no actuator test for the EGR. Maybe with another scantool. Anyways great job and thanks for sharing 👍
Thanks for commenting Dylan 😎
No egr bidirectional with snapon scanner
Great video Gerard. One question, if replacing the EGR with new, does this need to be recalibrated by Ford
Thanks Robert, No it does not.
Hi Gerard, what would you consider being a culprit, when I still get P0400 even though I have cleaned the original valve, then replacing it with a new Pierburg one and still get the flow problem and heavy pinging under load. When I unplug the valve, I still get the symptoms until the third start, when the fault is detected and engine light comes on. After that, there is no more pinging and surging under acceleration. So EGR is definitely the culprit or at least connected to it. Could be the passages in the head clogged?
Thanks Gerard for this video. If you want to make other videos for this vehicle, that would be really great too. 👍
💪💪👌👌
My ford fucos when I scan. The problem is EGR. then I replace for new EGR and I clear fault code but when I start they pop up check engine again.
Would this stop car from smoking on hi rev as what my car do
How did you check the resistance?
Wondering if there is away to actuate the actuator without using scanners. 6 pins, 2 powers and 4 signal (5V).
Hi mate
Did you find out about this?
Got a maz 3 I can't check if it works off the car!
Always make sure there's no dirty build up on your shaft
Fundamental advise 🤭😁
hello there ,,,,i have to say ,,,i cleaned the egr ,,,,and the hole that sits ,,,,,very well ,,,,it worked for while ,,,,,,and afte that the check engine came again ,,,,,at the end 7 months ago the car owner decided that the time to change the valve has come ,,,,,i dint push him to change it couse i knew that if we change maybe the problem remain ,,,,,so we bought a pierburg egr vale ,,,it worked well for 7 months ,,,,and now we have a check engine egain ,,,,,,whya problem remains ?> ==
What type of die did you use to remove the screw?
Hi Gerard. Did you reuse the old gasket in reinstallation?
Yes Quinn. No issues with this one at all also no engine light ever came back.
Did you reuse the old gasket?
What product did you use to get that waveform and expected resistance data? I presume that's a printout from something.
How to remove the air stuff???
I have a problem that I will explain to you if you have experience that can help me..??
What is the reason??
When I come I love gear on R or D and I am still smashing the brakes, there will be a jerk in the car..and also a jerk in the light of the car lights...?
But when I walk normally, the car jerks and the car lights up sometimes.... Also, when I'm in a park and the car is not working and I come to raise the bottles I get the shivers increase and rise more and when I remove the glass or put the gear on N, the shivers go. D you get shivers..?
Sometimes a sign appears on the dashboard of the car. I checked a computer, and it appears before it disappears, and a malfunction has appeared in P0400
What is the reason, can you help me if you have experience?? ..
Of course the car is Vitara Grand 2000 v4
Can you help me what caused the tremor problem?
12:22 haha he cut out the hardest part - coolant all over the place
can a coolant leak in te egr cause white smoke ?
Why would I have about a quart in air intake manifold?
Pcv valve behind inlet manifold at the jotyom
عندي مشكله بوضحها لك اذا عندك خبرة تفيدني ..؟؟
ايش السبب ؟؟
لما اجي اعشق الجير على R او D وانا مازلت داعس ع الفرامل بتكون هناك رعشه بالسيارة ..وكمان رعشه في نور اضاءة السيارة ...؟
بس لما امشي طبيعي بتروح رعشة السيارة وبتبقى رعشة في أضاءة انوار السيارة احيانا.... وكمان لما اكون موقف والسيارة لسى شغالة واجي ارفع الزجاجات احصل الرعشة تزيد وترتفع بزيادة ولما افك الزجاج او احط الجير على N بتروح الرعشة ..ولما احطه على R او D تحصل الرعشة..؟
واحيانا تظهر علامة على طبلون السيارة فحصت كمبيوتر وهي ظاهرة قبل تختفي وطلع عطل في P0400 ( بس احيانا تظهر الاشارة بالسيارة واحيانا تختفي)
ايش السبب ممكن تفيدني اذا عندك خبرة ؟؟..
طبعا السيارة فيتارا قراند موديل ٢٠٠٠ v4
ممكن تفيديني ايش سبب مشكلة الرعشة ؟؟
This is supposed to be a step by step guide but you did not show how to remove the air box and the rocker cover breather hose
Aahhh man.
The error came up.
Should I just replace the EGR valve and that’ll be fine or what??? I dont wanna become a mechanic 🤦🏻♂️
Too much Vtec :)
Thanks for the kind words
@@GerardBurkeBurkesGarage ???
@@DeeTeaDee Sorry I was trying to reply on multiple videos at the one time, It is difficult to get the time for replying so I do loads at one blast and that was for a honda video :)
The answer is if you can't find the time to do all the testing then the best option is to replace it, it is very likely to be the root cause. The testing procedures are to confirm this before replacement.
Ugh. Looks hard to reach 😒😒
Change an egr on a 1.8 tdci focus, then say this is hard to change. This is quite easy by today's standards
