How to reset VVEL and VTC info for Nissan 370Z and G37

[@NengHuynh]

Thanks to your instructional collection, I've cammed two VHR engines in my apartment garage, properly installing VVEL control shafts + stepper motors to your 1.585" metric. No fancy equipment either- harbor freight calipers and technical measuring set.
Position sensor calibration afterwards was a breeze via Ecutek; by stroke of luck, the first engine was already within the voltage tolerance before any position sensor adjustment.
You the man Seth! 🍾

That's the nicest complement I've had....I thank u brother!❤

@Seth Joyner Here's the clip of my latest first start-up, but before I remembered to adjust the position sensors 😅

Just got a 2010 g37x recently. It’s throwing a code for p0300 and p0011. Car is in limp mode with SES light on. No check engine, no oil pressure light. Gallery gaskets just got replaced and car is filled with 5w30. Could it be a vvel solenoid or sensor issue ? Or could it be something bigger

[@crashcrew7151]

P1606 and c1130 here, car is in mega limp mode max 2k rpm’s, rough idle, fastest I can drive is around 5-10 mph. It’s a 2010 with 110k miles. 2.5” intake and exhaust are my only mods, Help would be appreciated it’s my daily.

[@sanguinius7538]

Hey man, I have the exact issue. Did you figure it out?

[@antoniomtz295]

Do u need a computer to do the reprogramming on the vvel moduel ?
Or do you just disconnect the sensor and raley then key on the car for 5 sec ?

[@casper135]

Hey dude i just replaced my head gasket on my vq37vhr timing is right started up smoothly.. but the check engine light is on but i have 0 Acceleration do i need rest something ? Or any ideas why? Cheers

I have a brain buster for you Seth.
Swap car 95 240sx with Uprev flash Nats delete.
Ok so did a head gasket job on a 2014 VHR motor, kept everything else replaced, seals & such.
I could have sworn i had the engine in time. However, this motor sat up, clogged injectors idk. Got the heads decked sits pretty at 124mm if im saying that right on all 4 corners for both heads. ( or whatever the spec is i forget) .
Got it running first crank ! BOOM! AFTER some monitoring, exhuast manifold & downpipe are glowing cherry red.
I have had Corr performance tell me timing is retarded, too much fuel, too little fuel. Only thing i have not check is fuel injectors. I have reset VVEL with an Autel but no luck. Again, fires up every time. Timing advance read 12° at 1000RPM before i had to shut it off due to glowing headers. Any thoughts?

[@JJflowzz]

Heeey i have p0300 code tested alot and run a ecutek test ans hav vtc adanaced one on 63 degree and other one is 0 sensor have been replaced and everything gets power maybe vvl ecu dead or the cam phaser ?

[@sethjoyner391]

What's the setup, year, miles, etc? And which bank

[@Novachrono117]

Hey Seth, you seem very knowledgeable. Whenever you have the time maybe you can point me in the right direction.
I have a 08 i was getting P0021 so i replaced the cam sensor and the VVT solenoid. I cleared the code, drove it, got it up to 3k & straight back into limp mode. BUT the weird part is that the p0021 was gone & now i'm getting P0345??
I changed the crank sensor and no luck. Oil pressure is good and a fresh oil change.
I've researched a lot and there's nothing definitive, but it seems to be pointing to a slipped encoder ring or it jumped time.
What would be your guess?
I did replace the clutch, csc, and swapped the flywheel with a Z1 midweight about 5k miles ago. I went "by the book" with the install, torque specs, loctite and all. I'm pretty sure it would've thrown the code earlier if i installed the flywheel wrong, right? ha
I'll be dying to know what suggestions you have for me.
I've been struggling with this for a few months now. With my wife about to pop our first kid out, I don't want to pay for a two-way-tow on a roll back for Nissan to charge me $200 for a diagnosis. These day's the extra cash is always needed for another case or two of 556.. maybe some diapers too haha.
Thanks for your time & awesome video!

[@dustinvq37]

Any updates?

[@jao906]

I’m having a INT/v tim b1 with no signal b2 is showing signal and I have a leak in the cover right next to the solenoid

[@marcelolazarini997]

Great video. Tks. Can a vvel failure cause the engine to not start/fire? Same as vvt issue

[@sethjoyner391]

Sorry I missed this video....not typically...I've only had them misfire, stumble or run on 3 cylinders from general vvel issues...no start, no fire, may similar to a Toyota problem; however, on these engines the encoder wheel thats pressed into the vtc intake sprocket can actually slip and change its "clocked" orientation in which the cams magnetic sensor can't pick up the base reference point to fire the engine...these sprockets have had factory revisions...the first couple year vq37 can have this problem

[@obfort4174]

so do i have to reset if i replace the sensors? my car was reading bad sensors and wont start so i replaced them all and it still dont start and still reads bad sensors

[@sethjoyner391]

For sure absolutely...it will definitely not work without a relearn procedure

[@obfort4174]

@@sethjoyner391 appreciate it. I’m going to try and do that myself this weekend.

[@doggystyledave]

I just finished rebuilding my 370Z. It started up last night. I had to reflash the ECU to my previous tune.
It is revving up to 3K RPM as if it has a vacuum leak but I'm not sure where that would be.
I'm really hoping I don't have to get another remote tune from Soho Motorsports or admin tuning.
I only changed out the head gasket Cometic and put ARP studs in.
Are you saying that you move that sensor left or right a little bit until it is 0.5 volts then tighten it?
I did measure 1.585 in before I assembled the VVEL actuators. The motor was set at TDC when assembled and everything seemed to go back in place.
I was very meticulous and patient with the tear down and rebuild.

[@sethjoyner391]

Yea, once u have it in vvel reset mode...the sensors move back and forth like an old school tps to get u the desired .51v sensor setting range

[@sethjoyner391]

Sounds like u just need to reset and calibrate the sensors only

[@doggystyledave]

@@sethjoyner391 I actually got them both to 500mV exactly. I still have the revving issue. I'm going to have to keep digging! Engine sounds healthy tho!

[@edmonmayfield2446]

What do u think wrong when vvel on bank 1 and 2 is out of spec during idle and when u rev engine

[@sethjoyner391]

How out of spec? And how did it get in that condition? Any work to the engine or dtc?

[@braeder]

Seth, oil flows from oil pump to oil galley up to cams then top end right? Currently doing a root cause of why I lost 3 exhaust valves.

[@sethjoyner391]

Lemme try and make a video tomorrow showing oil flow path from pump to top end through the timing covers and the o rings involved

[@braeder]

@@sethjoyner391 Awesome!!! Look forward to it!

[@braeder]

my cam filters have a red residue like a red rag and are totally caved in; but I never used a rag on the bottom end. Which then implies during the project and the conflict I was dealing with at the time, someone whether my nephew or one of his friends, placed a rag in the crank case while the oil pan was off. And I want to cry.

Hey man, im having an issue where i get a weird sputter and spikes on int/t of like 60°/0°, and it just keeps swapping the bank it happens in. Its a 2013 motor and i still have good oil pressure. Ive gotten it to give me a code for each bank, but never at the same time. Also got a random mis code. Im at a loss, its swapped in a g35 sedan. I dealt with a bad swap harness for a year, now this haha. If you have any suggestions for me, id greatly appreciate it.

[@sethjoyner391]

I guess I'd start with removing and inspecting the vtc cover solenoids and internal dynamic seals (ive had physical grooves on the inside of the sprocket allowing oil pressure to seep past the dynamic and cause inconsistent lock up...overall oil pressure would still be stable.....testing vtc solenoids, checking wiring (also if this is a fresh swap make sure u didn't get ur harnesses for the solenoids backwards, more common on gtr, but shit happens)

@@sethjoyner391yo brother I’d appreciate any feed back I’m having the same problem p1606 but with u1024 2012 g37 cai, catback, and HFC. The car starts up prefect everyday but after driving for some time the car just goes into limp mode with NO warning it can drive super nice no weird idle issues but then BOOM limp mode I think is the module but then I see a bunch of threads were people say replacing the module does nothing so I really don’t know what to do.

[@sethjoyner391]

@GuapAnto I'd start off with observing real-time data of your vvel system to attempt to diagnose...if your vvel angles seem bizarre or unsychronized or if you are missing a data stream; it could be a failed vvel module located behind the fuse box and battery...I'd need more info
