Thank you very much. We finished the 2001 VVTI thanks to you. It runs perfectley. When I picked up the new head at Autozone I asked them about the unlock procedure (asked them, then did not volunteer any information). The manager said he didn't know but, had a guy that used to work at Toyota so he had him come out. He said yes, absolutely you must unlock the VV gear. Thank again.

You're a really good guy. i don't even need to do my vvti gear (i hope) but it's nice to see someone happy to help others. Much respect.

Thank you sir ! Best explanation I found, P00012 code is related to not having done this prior to install on 2ZE-FE Corollas

awesome job man you just took a load off my shoulders, i have been sweating this vvt thing for a while......thanks a bunch, and if i run into ya, the beers on me....

Thank you, doing timing chain and vvti gear on my car and the feeling to do research paid off, great vid. I also agree that dealers should give common people access to information to help folks with income trouble.

After doing some research I answered my own question.Why do you have to unlock vvt-i to install then lock after installed If you dont do it this way , you run the chance of wedging the locking pin tight....thus making the VVT-i inoperable. That's why you do it.

I’m doing this tomorrow, got two functional used OEM intake and exhaust actuator/ sprockets, as a result of Autozone selling me the wrong OCV which basically “locked” my Dual VVTI and prompting errors codes P0011, P0012.

Thanks for that info... Definetly a must watch if you are planing to work in a Celica (2000 & Up) or in a Scion Tc...!!! Thanks man..!!!

Good video. Mine was dirty inside with lots of burnt chunks of oil because it came from a burnt out engine. i had to opened, cleaned all parts really good, assemble it back together unlock and attach it to the shaft, torque to specs for my Toyota Corolla 2004 then turn it to lock, i almost make the mistake of assembling the head with the cam shaft cleaned by the machine shop, on the outside it was clean, inside air was no passing all over the cam shaft which made me suspicious that it was dirty inside; mine has 5 point star tamper security screws and it gave me hell to unbolt it, I destroyed the first screw but got it opened after some battle. I was glad i did once i saw the inside as almost all those little passages were pretty clogged up with gum up oil.

Hey not sure if you will know. Fitted a full chain kit on a 1.8 2006 Toyota celica. When I had new intake sprocket in my hand I somehow twisted it and heard a click. Fitted all back together not giving much of a worry and now fault code p1349 is appearing. Any ideas or do you reckon I may have locked pulley and will need to strip down again?

Awesome detail and thank you! Totally concur that manufacturers/dealers squirrel away too much repair info. Imagine a manufacturer that made available all tech data...can you say competition? Thanks again for the great video.

How you doing !?? I have the same problem with my 2005 Corolla, I´ve changed the gear 2 times but it still sounds when I start the engine, and I really don't want to buy more. My question is, what do i need to do to the original piece so it no longer sounds? It has to be unlock ? What do you suggest?

Does this also work for a 3SGE Toyota Altezza? ( Lexus IS200) ?

My friend working on a 2003 Rav 4, We are getting a P1349 what are the odds the sprocket was install wrong. And if we get a new one all we have to do is torque it?

Awesome video!

very instrutive clear eplanation

GOOD JOB THANKS CONTINUE TO BE REAL

Maybe you can help me out I have a 2009 Toyota RAV4 and I did the timing chain kit and after I finished the putting the chain and the front cover on I check the intake crankshaft and it had play on it so I order the intake.timing sprocket but my question is do I need to unlock it too if you can please help me appreciate thank you

Wow many thanks for this !!!!

Thanks for your help, im having the diese noise problem on my corolla, do you think im having gear lock problem???? if I unlock the gear I should fix that problem? , thanks in advance!!!

Great Video!!

Is there a way to test this VVT-i timing sprocket? I've got a problem with my car where there is soot (or maybe oil) covering the entire inside of the intake up to the throttle plate, but there's not the slightest trace of this stuff from the throttle plate to the air filter... I'm thinking that exhaust gas is blowing back into the intake at idle and it's either a valve, timing issue, or this VVT-i cam sprocket may be sticking in the wrong position... What do you think?

i am working on at 03 toyota corolla someone befor work on the car replace timing chain in the sproker vvt-i in the liht its on in the dash board now in replace the vvt sensor valve in the small filter in the liht still on do you think maybe \the vvt sproker it lock or need to replace cam shaft

I believe they tell you do do that is because it wont shear the pin inside there thus creating a check engine light code. Good information. I have never got it to unlock. You should sell that tool. I bet you people would by it

can the engine work without the vvt sprocket? meaning if i can get another sprocket and replaced it with the vvt sprocket, will it work? asking because i have a 2003 rav4 and this is the second time that i am replacing the vvt sprocket because its breaking, and when the engine is running, u could hear an engine noise and its really loud, sounds like a diesel engine.

Thanks Wydranator!

Very helpful info that scion 1.5L motor has that problem with malfunctioning VVT-i cam sprocket

(Need HELP!!!!!)Sir i have a problem with my toyota d4 1jz fse petrol engine, i spend lot of money almost 2000$ & i clean every thing but the problem is still there..my car stalling only on 65 to 70 kmph with b/w 2200 to 2400 rpm..i check every thing no code is there..i researched a lot on internet.. i only solve the problem by disconnect vvti solenoid..now the problem was gone by disconnecting it..but this is temporary solution the performance goes down & i also check another vvt solenoid but problem still there..i researched a lot on internet i think 70% chance is torque converter beacause when i start car in morning the car transmission dont engaged on drive but only in reverse..after 5 to 10 minutes after cold start every thing is fine..my car moves ok.. there is little white smoke coming out from exaust ..petrol average is pathetic..3 km per litre in city and 5 kmpl in highway..i also overhauled the engine..the fuel consumption is also bad and stalling problem on 80 is still there may be its beacause of torque converter.. one mechanic told me that maybe its your crankshafts issues..no code is detected by computer scanner..only one code is there of vvt beacause of disconnect..plz plz help me

what would it cost to have this job done just to replace the variable valve timing mechanism...... mine is rattling when I turn the engine off it does not rattle when I turn the engine on

i think they tell you to have it in the unlock position so it wont shear off the pin inside the gear when you tighten it.

gsr2envy i have been hunting high and low trying to figure out why it has to be unlocked just to torque the cam bolt. I think you have answered it the best i have seen yet! Locking pin out of the “lock up” position keeps the pin “which is actually a finely machined shuttle valve pin assembly” for getting bound up and scored. I had a rod bearing come apart shortly after a rebuild so i am taking everything apart cleaning it all really well. So far i pulled apart one exhaust cam phaser and found a tiny triangular piece of metal in it. Must have been in there since manufacturing since it would not fit through any passages. Any leads on the five point pentalobe tool toyota used for these bolts? Going to just get them all out and use grade 5 bolts to reassemble them with some loctite. Thanks for any ideas you might have. Figure putting this out there might save someone hours of searching i have had to do to get to this point

thanks a lot man!!!!!!!

Just dissected a cam gear for a 2zzge. The manual is crap. I could be entirely wrong about this, but I found that it's easier to remove the Toyota stealership 5-pointed tamper proof bolts from the cam gear cover with some channel locking vise grips and replace those bolts with ones of the same grade but not 5-pointed. Then disassemble the cam gear, clean out whatever crap is in there, if any, and manually unlock the pin by just pushing it outwards and turning the cam gear so it's not locked in the groove. Note: If you're transferring the camgear to another camshaft, i highly recommend cleaning the insides out, because once you undo the bolt that connects gear to cam, the original loctite material in there before will circulate inside the gear housing. Now replace the cam gear cover with the new bolts and some high temp red loctite threadlocker. making sure everything is where it was even the lock pin spring. The manual doesn't state torque specs for the cam gear cover bolts, but 12-14 ft-lb should be ok. The bolts weren't extremely tight. Now torque the cam gear to the camshaft to spec with high temp red loctite. Then spin the cam gear so the pins locks in it's groove. At this point the cam gear will not spin once locked. Note: Before putting everything back it may be a good idea to lube all metal to metal innards of the cam gear to prevent any unknowns during initial startup. Maybe use assembly lube. Also, the thread pitch for new bolts are Flange type M6 1.0 mm pitch and is 35mm in length. The original flange bolt length is like 33mm, but 35mm is easier to find and will not interfere with the camshaft. Will post a video for those who need visuals.

Quick question. So is this the proper way to reinstall the cam gear onto the cam? 1. Remove the cam from cam gear. 2. Unlock the cam gear from full advance. Either remove those 5 point bolts or blow air into the gear. 3. Install the new cam onto the old cam gear and torque down to 40ftlb. 4. Once they are all together, rotate the cam gear back to full advance which is clockwise. Does that sound right? Is the point of unlocking the cam gear so that when you torque the cam back to the cam gear, it doesn't bind the internal pin?

Yes, if you're removing the gear itself, you'll want the pin unlocked or not in the hole. Then once you've torqued it down then turn the cam gear and the pin will drop into the hole and be locked. Be very wary of which side the little metal pieces go for the plastic keys. I made the mistake of positioning it where it would scrape the internals of the gear the first time. Good thing I double checked xD

thank you very much.

Excellent video.... I may be sending you an email in the near future. Thank You Sir!

i have a 2001 toyota corolla need to know more about this "unlock and lock" thing

Hey I got a 2000 Toyota Celica gts I think my cam phaser is unlocked can you look at all data for it for me and help great video man

The reason to unlock it is to prevent the pin from breaking during bolt installation.

@fernandohood5542

Does it need to be unlocked during bolt removal?

Though is you first but its really cool.Thank you for share.

Has to be unlocked to ensure that torque applied to the camshaft bolt does not damage the lock pin.

Hello, I have the same problem. You could solve it?

I bet the reason they want it unlocked to torq down is so you are not putting pressure on that locking pin when you torq it down so as not to damage the pin. then once its torqed down you lock back into place so it does not rattle on first start up.

hi Wydranator are you still able to email the instructions?

Why do you unlock it and what happens if you dont unlock it? Toyota of Savannah told me to install it in the locked position

Thank you

Hello Brother 🙏 👌🙌👀 would you please guide me : is this right? 1st : after I took the gear out , first we install the gear assembly then I torque it to 47 psi then lock it then I install the chain . Am I correct .please let me know if I am right . Thank you for your response .🙏🙌✟✟✟🇺🇸

why do you have to unlock vvt-i to install then lock after installed

Hi I have same problem. I take out by mistake. Now I don’t bow how to put black

Is that the same processor as a 06 Nissan 2.5 motor

After its torque at 47lbs then turn it one way if not the other way. 21 psi click You will feel it then you'll know I don't know why, But trust me I made a set tool this is what works

Hello! Thanks a lot for this video! Can you send me the instactions?

Whr a get vvt gear for toyota corolla 2007 model 3zz

What will it happen if you did not unlock the pin pls

Thanks

Is fhis the same thing for the 03 altima 3.5?

Hi can anyone explain why to unlock, what makes the (mechnical) difference while tightening?

I have no idea. I put mine on and then unlocked it and it won’t line up the same as when i took it off. It seems my stock one was unlocked when it came off but not sure why you you need to lock it. I’m stuck trying to figure it out. I out it on unlocked then unlocked it. But i don’t get why and why am i having a problem. I must have something wrong like it send the valve might be hitting each other because i can’t spin my cam closer to engine wall easy and when I’m spinning then they are like popping forward half way thru a cycle. I don’t remember it doing that before i put these new vvt sprockets.
