hey i've posted up bouts my v-tec not workin before, but didn't find the answers to the problem, aight i'm bouts to post again, i drive a db2 b17a1, n when i hit 5000 rpms my v-tec kicks for like almost the whole first gear, and than after that the check engine lights up n v-tec won't kick anymore, sometimes it can go into 2nd gear wit v-tec kickin but thats it, now it drives like an ls without v-tec, what is wrong wit my car, i have a buddy say it could be my timing belt is not correct, i bought my car like dis from the dealership, i read the ecu light code, n the check engine code blink 8 times, so i figured dat code on the acura chilton book manual n it said something to do wit (TDC) top dead center, what the hell is dat, well if anybody can help i apreciated it, thanx 4 reading

 

It all comes down to oil pressure to make your vtec "work" but just because its not working doesnt mean thats your problem. Have you checked the vtec solinoid? If worst comes to worse you can rig up a msd rpm activated switch it is really easy to use. Hook that straight up to the vtec solinoid and program and your set!

 

sounds like yur in luck because ls's are betetr than gsr's anyways. but yeah tehres a coupel thingas. if the manual says that then thats probly wut it is. also yu could need a new vtec solenoid. somethin else my friends dc2gsr burned a valve and his vtec would still kick in but wouldnt last all the way through the power band. having a diagnostic ran on yur car woudl tell u exactly wut it is tho

 

datz what i was thinkin, it could be the v-tec solednold, i've change ecus wit a friend, same problem, he had an 94 gsr ecu, which is still obd1 i think

 

vtec is a ingenious system created by japan. Don't know how they thought of it and how they made it work perfectly, but damn they are amazing at what they do.

vtec is the thing of the past. Like 15 years ago. Now they are designing electronicly controled valves so they are always variable. Now that is smart.

Past or not, we still use b-series motors w/ vtec that are nearly 15 years old, and still swapping them into our cars, and still run like champs. Anything more they do gets better and better.

 

OP did you check to see what codes you are getting.

http://www.howstuffworks.com and search vtec. You will learn how it all works.

um was this a joke?if u think vtec is a thing of the past why r u on honda tech? and just so u kno vtec isnt something that was hot 15 years ago. 15 years ago was the first year anything in the united states had vtec

No it wasn't a joke i think hondas vtec system was engineneered with not alot of thought they just wanted to get it out there before the other companys did, such as nissian, there variable valve timing system is far superior to hondas vtec.

 

this is what makes vtec.

 

take it to a shop since so many things could be the cause. You'll be waiting and trying things for weeks and spending undu money on parts you don't need to fix the problem.

lol not as stupid as you if you think that will not work.

so tell me, what is going to tell the ecu to add more fuel and change the timing if you're running vtec off an rpm activated switch? you're an idiot if you think that's a good idea.

oh really your friend has a DC2GSR? Pics plz.

Sounds like your vtec solenoid most likely. Are you running a 1-wire VTEC? If you are, then its not your oil pressure or anything like that, because with only 1 wire VTEC engages at a set RPM regardless of oil pressure.

PS: "An LS without VTEC." Don't think I've ever seen one with VTEC, aside from the obvious.

I'd try to be more helpful but you type lyke dis an shiet an j00 providead veree lil info yo.

well im sorry that i do it on my car everyday and it works totaly fine fuel curves cross over and everything.... can you explain that? the ecu automaticly adjusts the fuel curves and timing even if vtec doesnt cross over.

your dumb... if your going to talk **** atleast get your facts straight first

 

Having an RPM activated switch is the same as having 1 \-wire VTEC. It's definitely not good for the motor in the long term, as one of the most important parts of VTEC is oil pressure. But it works for the people that gotta have that VTEC!!!!!

it WONT cross over without the oil pressure, thats what pushes the pin over to lock the rocker arms in place

 

I like how everyone just started arguing about VTEC without helping the OP out. Not that I blame you, it is hard as hell to read his "writing". Anyhow, to answer your question, TDC is a sensor in the distributor. Try a known working distributor and see if it still throws that code. If it does, there is probably a problem with your ECU or wiring. This is one of the wires that is normally shielded because it is sensitive to EMF.

Yes, it is merely hydraulic pressure that makes VTEC "work". Yes, it is an old technology. Yes, they are trying to develop solenoids to have infinitely variable valve lift and timing. Yes, it is hard to develop because the amount of current drawn from the solenoids would be ridiculous with current 12v systems. Yes, pretty much every auto manufacturer now has their own form of variable timing and/or lift system.

He PM'ed me and I gave him all the help he needed.

 

hey damn yo, i didn't think i would get some kind of thing going on here, but yeah, i don't know bouts my v-tec, its just the way it came, oil was leakin from the v-tec solednold before when i bought it, so hmmm could be

 

here's a question...

what makes people consistantly spell an easy 4-letter word like "VTEC" wrong??

There are no hyphens and no "H"

to ignorance

Do you pronounce it Vah-Tech or Vee-Tech? Some people like the hyphen it because thats how its pronounced.

Look how the OP spells everything. That bothers me alot more then the spelling of Vtec.

And St Jimmy, you know your ****. Keep up the good work.
