- if u changed vvel motors, cams, built the engine, built the cylinder head and are having engine performance issues, you likely did not degree the control cam...obviously, in the fsm it says you are to never disconnect vvel control cam from the stepper motor...this is why, and here's how to fix it
Thank you
I got a g37 sport 2010 Im running codes p1093, p1089, p2A00, and p1608 its also going into limp mode.
First it was just p1902 got the little black motor on the camshaft solenoid adjuster on the left side i plug and played it didnt do any resets of any sort the car drove for a week till it went into limp mode again when it started showing those codes i listed first
See if you can get a scan tool to observe real-time data of vtc/ vvel angles to see what's going on
I went to z1 to get a quote on how much it would be to swap cam and they said north of 7k, they said it could be even more depending on if there is valve clearance issue. They clame some engine even form same year are slightly different. Did you run into any problems with this. Im going to swap to the c2 cams and donthe work myself
Sooo...it can get complicated, if it requires a spring upgrade, and u will have to measure cam lash and make the appropriate lifter bucket selection... everything they said is accurate as far as process...the price point is a bit high; but that may be more related to their work load as it's a very time consuming job to only do a cam upgrade
Oh, and also...just from in the industry 5k-7k would be about the going rate, it's an uncommon job...most cam upgrades are done during an engine build process where it's not much additional cost since the machine shop has the cylinder heads in a stripped down condition, they are easily upgraded
@@sethjoyner391 I figured as much I have two engines on a stand and one iny car all of them around 100k miles but asked if I could drop my. Engine off and have them install cam and still was a no. I think I'm going to attempt it myself I have built a few engines and done a few g35 timing jobs so I feel pretty confident plus your vids come in clutch. I just can't see myself Paying 7k just because I'm being lazy lol
Ok so I have a question, after installing jwt exhaust camshafts, mechanically setting the vvel to the 1.585 in gap, do I have to reset the sensors electronically via ecutek? If so can it be done by my tuner. and will the car be able to start before the vvel reset. My tune date is in about 7 days and I’m so nervous. Any help or advice would be so extremely appreciated.
After watching your other videos, and doing more research, I’ve come to the conclusion that I’m going to mechanically clock the vvel motors the way I’m supposed to, then after timing the car, and throwing everything together, try to start it. From there have my tuner use ecutek to set the sensors properly.
@@coenmcleod9441 did that work? I'm doing cams soon and am curious
@@coenmcleod9441how'd it go
@@aaronthemartialmechanic893 good. Forgot to set valve lash and tire it up.
Hey my car isn’t starting after installing jwt cams of course took the vvel off for that do you think this might be my issue
Most certainly...its beyond common if you changed cams
I have other videos that are more in depth about it...u also need ecutek or nissan consult to reset the actual vvel sensors as well as this mechanical adjustment
Ugh me and my friend hated doing this, Hr heads ftw!!
Facts!!! So much easier
Am I able to fix my bank 2 side by just removing the valve cover and doing it that way or do I have to remove my timing cover?
Nvm im dumb lol
Hey Seth, question. I know the control cam has to be locked in that position to make the correct measurement for the motor. But once that is set is there a certain position that the control can has to be or should it just stay in that spot?
Thank you!
-Daniel
It just stays in that spot and you move on to the next control cam....this will allow the electronic vvel reset procedure to be possible with the sensors themselves after you do this
@@sethjoyner391 sounds good, I'll do the reset procedure next! Thanks again
Will a tuned ECU affect the process of getting the sensors set?
Sorry, I missed this...not sure about up Rev...but with ecutek, the tune has no effect
If you take the DC motor (black cylinder with the 4 Allen heads) and reattach, do you need to adjust anything or reprogram?
To be honest, I'm not sure...I end up replacing the whole unit....one would think just pulling the motor wouldn't.....definitely give everyone some feedback if u don't have to reset
Did you figure out if you have to or not?
Hey Seth, I hope you can help me with this issue. I mechanically adjusted both bank 1 and bank 2 vvel to 1.585 gap/ 5.5 degree. After assembling everything to adjust vvel position sensors I can only get bank 2 to .50 but when I adjust bank 1 its way within range meaning it's not centered where it's supposed to be, it barley reaches .50. So, i turn on the car and everything runs fine, it idles with no issues. Once i get on the freeway to about 60-80 mph it goes into limp mode / loses power. Any thoughts ?? Your response will be much appreciated.

@tonysautorepair8809 hmmmm....yea it's definitely tricky....I don't know if I ever didn't have one dialed in to the .51 however...other questions 1st...some may seem dumb.....is this fresh gas in the car, why were u into the system, and have u updated your vvel module computer to a newer one (08/09 have chronic vvel module problems that do wierd funky stuff) just trying to get familiar with the setup
@@sethjoyner391 Hey Seth, super late reply. I ended up finding the issue. There was actually a tiny crack in the intake manifold plenum causing a vacuum leak. The reason why I adjusted the vvel position sensors was because I did the head gaskets. Since the vehicle was already misfiring due to the head gaskets before the repair, I never knew there was a crack in the plenum up until the repair was done. Thank you for your response !
@tonysautorepair8809 respect for an impressive and bizarre diag...hopefully someone will see ur post in the comments for good info
i have 2009 g37 convertible. When taking off the vvel's and replacing them is it common to have a lack of acceleration? if so how do you fix that? shows code for vvel...Everything is timed and runs smooth as silk...just won't accelerate...please help
The vvel motor and control cam need to be rephased mechanically, vvel sensors need to then be adjusted and reset
Remember....vvel is responsible for intake valve movements
@@sethjoyner391 Have you ever had the experience on working on the VK50VE? It's basically the V8 version of the VQ37vhr. I was wondering how did you come with that value of 1.58 and if it's the same settings for the VK50VE as well.
@@top-notch9761 I doubt it's the same...however, if one had a stock engine and put it up on #1 cylinder and measured they'd have the info (like a junkyard engine, or rod knock etc) that's basically all I did to come up with that spec
@@sethjoyner391 Salute you for your quick response. I was thinking of purchasing one of the VVEL motor from Infiniti to attain my measurements due to the fact that these engines are super rare and usually sell used at the auto parts for 3500 and up. What I got from my engine on both banks at TDC was 2.15 inches.
Tengo una duda
Grate❤
hi, I have problems with assembling such an engine. Where can I find information on installing and adjusting the vvel shaft, camshaft?
Just my other videos as far as I know
As far as setting the lifter lash...the fsm has all the bucket heights and lifter lash specs
Спасибо!
@@sethjoyner391 Thanks
@@sethjoyner391 manual:
3.Perform adjustment or replacement if the measured value is out of the standard.
Refer to “CAMSHAFT (EXH) VALVE CLEARANCE ADJUSTMENT”. (Exhaust side)
Replace VVEL ladder assembly & cylinder head assembly. Refer to Exploded View. (Intake side)
■ CAUTION ■
Never adjust valve clearance on the intake side.
NOTE：
Since the valve lifter (INT) cannot be replaced by the piece, VVEL ladder assembly & cylinder head assembly replacement are required.
Perform adjustment depending on selected head thickness of valve lifter (EXH).
■ CAUTION ■
Never adjust valve clearance on the intake side.
1.Measure the valve clearance. Refer to “INSPECTION”.
2.Remove VVEL ladder assembly and camshaft (EXH). Refer to Disassembly and Assembly.
■ CAUTION ■
Never loosen adjusting bolts and mounting bolts (black color) of VVEL ladder assembly.
Hi bro, is it also possible to configure the vvel system on the VK56DE engine, or are there other gaps and adjustment procedure?
Probably not, it would be extremely technical to make an adaptation and would more than likely require a head swap; I don't have enough knowledge to contribute much here
When I put everything back together, do I leave the cam locked like how you had it?
Yessir
I mean honestly after u measure, lock the control cam and tighten the bolts, it can be moved around or the engine assembly could be rotated etc before the vvel reset procedure
@@sethjoyner391 perfect! I am having an issue where the sensor reads at the correct value .5 then it changed to some high value like 4.8, does this mean I need a new VVEL control module? Thats the only thing I can think of. I am getting a code U1000 aswell as the p1092
@@Stockclipz what scan tool or software are u using...also in my experience..bad modules just won't supply power or can com with stepper motors and u will be missing like six attributes of vvel data..it's normally relatively obvious
@@Stockclipz also...describe what that p0192 code is
