This Guy knows his stuff.
Awesome job! I've research a ton on these valves and issues relating to low fuel rail pressure errors and no one explains HOW these valves can actually produce such errors. It's just as I suspected- mechanically hanging up.
Great work Gerard! This is probably the most informative video on this problem that I've come across. I experienced a SCV failure back in 2016 and after shelling out $800 for the local specialist Diesel mechanic to fix it, I thought I'd have a crack at it myself this time. Mine failed again a couple of weeks ago and threw the same codes. $50 for a replacement SCV off ebay but I wouldn't exactly say they are easy to replace. Access is a nightmare (particularly the lower bolt) and if you accidentally drop a bolt or your Allen key it finds its way into the notch of the engine mount bracket and is completely unreachable (trust me! Don't let anything fall). I have exact same car (07 4JJ1) and this seems to be its only real weakness. Just clicked over 300,000.
This repair was done earlier in the year and has solved the customers running issues.
Link for part - ebay.us/Hev6eE
Part numbers for the SCV are VSC100GEN / A6860EC09A (Nissan Genuine Part Number)
As always, thanks for watching
Did this replacement need re programming in the ECU please?
Thanks for your clear description of what is going on in this situation. My Captiva has a low pressure fault and I was told that the HP fuel pump needed to be replaced. I've stripped and inspected it and found nothing wrong with the pump. The valve operates electrically, but I'll see if I can get into it to inspect it for wear. I've been told by another service business that there may be a seized injector that could be causing the low pressure issue, so have to investigate that as well.
Very well explained direct and to the point no rubbish talk, but what else would expect from an Irish man. Thanks for the information Cheers.
nice presentation , thnk youi so much make more videos brother
Great work very informative. Thank you so much. I'm from the Philippines
I had the same symptoms and rough idle occassionally on my GM 1.7cdti. Mine did not have scoring but it was dirty inside and when i cleaned and put it back the rough idle went away and the low pressure issued rectified. I have ordered a new part and will replace it when the weather warms up. I was wondering about it needing calibrating to the engine, so i recommend keeping the old part until the car is in good working order and you are satisfied. Thanks for the great video
Thanks for taking the time to show this. Interesting and valuable info.
No problem, that's for watching and taking the time to comment 👌
@@GerardBurkeBurkesGarageI have problem with my 2.0 d4d toyota rav4 could you help please
Great video again, thanks Gerard ⭐
❤❤🙏🙏❤️❤️
Fantastic detailed video, no bullcrap, straight to the point, Sir you now have a new sub. Just one question please, Does this part replacement need re programming, I'm about to do mine on a Mk7 Ford Transit 2.2 TDCI, Thank you 😎💜✌🏻
Cracking video cheers 👍
Interesting. I would imagine that most shops wouldn't go to this detail because of the labor cost.
Great job Gerard, Thank You 👌👍🙏🙂
Cheers Pat 🙏🙏💪💪
I did all these testa found tiny bit of scoring. My question is when i did the battery test it goes in and out as should but i noticed the circlip moves around a bit is that normal?
Hi there,
very useful information.
can you tel me please what is your opinion on this problem?
p0087 intermittent on diesel 2.2 idtec honda.
after deleting the dtc all works fine.
the pressure on freeze frame shows god pressure in the rail.
I am lost.
thanks.
Hi Gerard very informative video My car suddenly wouldn't start low fuel pressure could the valve be the cause in other words does the valve creates the pressure
I've just changed an engine over in my Colorado 4JJ1 2009. The donor engine is a Low out put turbo model of which I put the Original engine Hi Output turbo and manifold on the Donor engine. NOW it cranks but wont start.. Do the injectors need to be changed too from the original engine because of the turbo out put difference, I've not programmed them in? Im getting no fault codes..
Can it be checked while installed as well by connecting power and listening if it clicks?
My scanner sais my scv fuel rail pressure is fluctuating between 30000kpa and 28000kpa at idle is that bad ? It is brand new. Also woule this be causing problems when cold?
I've just bought a 2008 c-class Mercedes 320 cdi.Drove perfectly on test drive,however this was just around a built up area.After buying the car i was doing 60mph and floored it to pass 2 cars,EML light came on,fault code 11b800 "The control deviation during rail pressure regulation via the quantity control valve is too high"
The car drives faultlessly apart from this so i'm thinking the car's just struggling to get enough fuel at higher revs.
Could this valve be a possibility on mine?Sounds like it could be.Thanks.
what should common rail fuel pressure be when engine is not startet yet and fuel pump have primed engine. i have a FIAT qubo that will not start at all and i have FRP at 4400. do you know ?
Nice easy fix. Thankyou
Thanks for watching 🙏🙏👌
Nice find!
Thanks very much, appreciate the comment
Good catch mate 👍😉
Cheers mate, another fix = another happy customer
Gr8 video, thanks Gerard
🙏🙏💪💪
Would this cause a hard start Citroen nemo im getting p0089 pressure regulator performance and very hard to start on a morning and after is left stood for a hour
Brilliant great indepth explanation thank you " good work !! "
💪💪
Just an update on our problem We had the same code but found it was a cracked / hole in the diesel feed pipe, so air leaking into the pipe . This was due to the chassis having cracked just behind the cab 😢
Awesome, thanks!
🙏🙏
top bloke well explained have same code on volvo c30 1,6 d going to replace fuel filter first if that doent work the pressure reg valve next fingers crossed not pump faulty
thankyou,, did you get an answer from the client that it did in fact solve his issue just noted that you did inform us further down the comments, very informed video
P1093 Isuzu d max สรุปได้คือscv เสียใช่มั้ยครับ
Hello.. I have a 2013 renault/dacia duster.
The car suddenly stopped working when I was driving it..
apparently the FVR(fuel
Intake solenoid valve) was faulty (thats what the mechanic told me.
Now I got another pre used valve and when I connect it to a 12 volt power source, it pulsates forward and backwards.. about 3 times a second ..
Now when I connect it to the car, (the car connector terminals read about 9.5 volts (which is correct I guess because I confirmed it from another video)
But, the solenoid doesn’t open.. it keeps vibrating.. and the engine doesn’t start..
Now, I cut the isolating rubber ring on the old valve and connected it (basically bypassed it) and the engine started..(with low fuel economy but it runs) thus ruling out pump, filter issue..
I am not able to figure out if it is an ECM problem (maybe the voltage drops on load.. im not able to check on load voltage because the connector wraps around the entire connectors.. but when the connector is open, it shows 9.5 volts
I would also like to add that since a few months the car was giving a fuel volume regulator control circuit range/performance P0002 error (but it used to go away on its own)..
So again, should I get the ECM checked? Or it could be that the other used valve is faulty as well?
can this cause crank no start issue .
I used to get my peugeot 307 2L HDI shut down on the highway towing a heavy load. I did a scan and got something similar. I can't the scv and the other pcv and cleared faults and no worries then.
Now i have rough or surging idle intermittently bit a lot in my ssangyong actyong sports. Probably the same thing
Hi Gerard I doubt you’ll see this but if this manages to reach you, I really need your help. I have a 2ltr cdti kuga with high fuel pressure and engine cutting out in high revs? When flooring it.
I’ve been chasing this issue for a while.
Things done so far.
Changed fuel filter
Changed high pressure fuel pump & regulator. Second hand so second guessing this. How Lilly is it to get 2 faulty fuel pump & regulators
Changed high pressure sensor.
Done leak off test. All seems ok
None of this made any change.
Car gives up fault code. P1169 (fuel pressure in range but high) but when restarted after stall. Code clears and car goes back to normal.
2012 tdci. AWd 136kw
I’m now thinking it must be some kind of blockage in return pipes or blocked injector possibly. (Tho leak off test seemed ok
Causing high pressure build up. If revs are kept below 4k, car runs perfect in lower range . Starts perfect. Idles perfect.
Just thought I would throw it to you and see if you can suggest anything. I’ve been pulling my hair out and I’m skint now, funny thing is. After changing HPFP the issue was precisely the same. I can make the car do it at precisely 4.5 k revs 5th gear topping 80+. It happens at this same point no matter what I do
Thanks in advance
Very informative video Gerard! Well done!
I had "P0045 turbocharger/supercharger boost control a circuit/open" and I have replaced my turbo yet the code came back again. Checked the wirings and the turbo computer and all seems well. Do you think a lack of fuel and power is throwing off my boost sensors hence showing this code? I have ordered a new SCV and hope to install it in coming days.
My engine is 1KD, GX Prado 120, auto 2004. Thanks again for your videos, appreciated!
The description of the code would lead me to be certain of wiring and actuation of the boost solenoid before moving on to anything else.
Best of luck with the repairs, thanks for watching and commenting on the video.
@@GerardBurkeBurkesGarage Thank you for your time replying, appreciated! I will keep you posted on this tread on how it goes. Regards. Shyaka
I have a vauxhall astra h 1.7cdti (izuzu)with a non start issue low rail pressure no codes showing. Could this be the problem thanks
Same issue with a meriva b 1.7cdti, ran fine yesterday then non start again
Should I disconnect battery first,and then removing that regulator?
Yes you need to remove the battery to get space to access it
Hi brother..l am having a p0192 on my isuzu kb300 lx dteq 2011 model..the engine light is on and and can rev over 3000rpm..😢😢😢 am depressed
Thanks son .mike Scotland
GM Vectra 3.0 Cdti with the Isuzu suffered with SCV problems also, Expensive part here in my part of Europe.
👌👌
Great video, very informative.
Have you had any experience of the 2.2 puma engine regarding rough idle and stalling and losing power when hot? Gives me P0094 code. Could it be the same? If i change ut do i need to do a pump relearn?
Is this also a common issue with the 5.2?
Yes
noice
come fix my car i have the same problem and i really want my car to running be again. i took the car to two garages but they didnt fix it and im afraid the local garage would charge me alot.
Hi ! in mine move the piston when I shake it, is the spring broken? unfortunately unmountable,this is renault pressure regulator.
You are a great teacher thanks May GOD BLESS YOU AND YOUR FAMILY AND YOUR WORK AMEN AND AMEN HALLELUJAH ❤️❤️❤️
