okay, so i run a test light... but on which wires? is there only two? i honestly haven't had a chance to see.
i'm running a '94 GSR and can't hear/feel any difference at 4400
i DO, however feel a hit at 5800 when the secondaries open up. if they open, does that mean i have vtec, or are they independent.

thanks.

ud have a CEL if there was a problem

 

it'll trip the cel??? sweet!

 

if vtec solenoid doesnt work ull get a 21 code.

How does the ECU know if the VTEC solenoid is working or not?

no need to be a dick. do you think we all sit around on our friday and saturday nights, taking things apart and studying schematics?
i see not all people here are down with helping other people to learn more. i bet when you first started you had no idea what a friggin torque wrench was.
sorry, oh heavenly father. we'll refrain from such impudent remarks in the future.
jeez, man. lighten up, will ya? i ask dumb questions all the time, and i'm sure everyone else here has too, at one time or another.
his question wasn't even dumb. just inquisitive.

ill be the mature one here alright, youre gay i wasnt even making fun of you. if you looked i quoted the retard below my first comment...and wouldnt you think that someone should know the ecu controls all electricals concerned with the motor...
ive also always known what a torque wrench was dousche. try a better example next time...and figure out who someone is talking to before you make yourself look stupid newbie...

Actually it's not all that smart. It takes a look at the inputs from the sensors and compares them with an internal map and sends out the corect signals. It's really good at following directions but it doesnt have to think at all.

So I ask again, how does it know if the VTEC solenoid is good or not?

well, okay, Mr. Adult. if you read MY post a bit more clearly, you'll see that i know you were not making fun of me. you were, in fact making fun of the post after mine. i was just saying to lay off the guy 'cause there's nothing wrong with the question. some of us don't know every little detail. i, for one, am good on the mechanicals.. but when it comes to electronics?? palease! i'm damned near clueless. no, i SHOULN'T know it all. i'd love to, though and will one day soon. hell, i went from a 2000 Mustang GT to my GSR. i'm learning a LOT of new things. i only JUST learned to do the timing belt last week.
hey, Mr. Adult.. calling someone gay is definitely grown up.
*always known what a torque wrench was, huh? nobody ever explained it? you never had to read or mess with it to comprehend it? you must have been born with the knowledge. in that case, you're a bad *** ****!
don't get all booty hurt, i was just saying to lay off of those of us that don't fully understand every detail of these motors. we're not all gods like you.
re-read the post and see that the newbie now owns you, Mr Adult.
aaaaanyway, dousche?? i've never been called that. i don't even know how to spell it. hell, at least you have a sense of humor so i know we'd get along if we ever met in person! good to meet ya.

smart was being sarcastic

no computer can "think" yet...

 

"mature one" was sarcastic as well.

mr adult makes you sound like a fuking moron.
i do have a sense of humor, and im glad youre learning new things
we use dousche a lot here in NOVA...well at least my friends and i do
no noone ever explained a torque wrench, the name is self-explanitory
and i was assuming that he knew that the ecu controls all of the motors electronic ongoings due to his "post-count" but then again my friend with 200 posts knows more than most people as well.

I don't think you know yourself but your acting like you do, why don't you enlighten us. I ask once again, how does the ECU know if the VTEC solenoid is good or not?

A cutting, often ironic remark intended to wound.
A form of wit that is marked by the use of sarcastic language and is intended to make its victim the butt of contempt or ridicule.
The use of sarcasm. See Synonyms at wit1.

yes, Mr. Adult, i too use sarcasm
*you're right... "dousche" makes you sound smart, as opposed to "Mr. Adult". especially when it's spelled wrong... more than once. that does NOT making you sound like "a fuking moron". see:

douche

n.

A stream of water, often containing medicinal or cleansing agents, that is applied to a body part or cavity for hygienic or therapeutic purposes.
A stream of air applied in a similar way.
The application of a douche.
An instrument for applying a douche.

in case you don't understand the moral of this post, please see "sarcasm" once more. thanks for playing.

i'm sure the guy knows what an ecu is and what vtec is, also what a vtec solenoid is.. just doesn't know how it works from the technical aspect.
much like my sorry example: you knew what a torque wrench did, but you had to figure out what the numbers meant, how you know it is tightened to that setting, and how to dial in or lock the numbers. that's what that guy was doing here: figuring things out. can't blame him for trying. i'm curious to know the answer myself.

as you said.. post count means nothing. probably just means he's asking alot of questions, which would be good. who knows? there I GO assuming now.

when you assume, you make and *** out of you and me, blah, blah. you know how it goes. see? at first i thought you were a pimple popping 15 yr. old with a learner's permit. but now that all the chest beating is done, and we've explained ourselves a bit better, i can now assume (hehe) that you and i are both intelligent adults. i'm not sure if i meant any sarcasm there or not. haaaaaaaa.

anyway, it's good to meet you all and good to get right in the meat of a discussion. i appreciate it.

so, kinda' off thread: where is everyone from? any cali people here?

Actually I do know how it works, but when I see someone posting incomplete or wrong answers (hybridvteceg) I ask questions. (There are problems with that keep VTEC from working without setting a code.) I bet he doesn't have a clue on how the ECU knows if the VTEC solenoid is good.

yeah, i was assuming again hehe. well, if you figure all this stuff out, lemme know. i'm still not 100% convinced i have vtec. that's why i'm trying to figure out which wires i need to run a test light on. i've still found nobody to tell me which ones they are... nor can i find anyone to tell me if vtec and the opening of the secondaries are independent of each other.
i'll try some other boards to see if i can't find something out.

thanks anyway, ya'll!

Hook your test light to the solenoid wire.

The "VTEC" and the "Intake Air Bypass" systems are seperate.

 

hey KAJ, Chiovnidca is a honda technitian (spel?) so he pretty much knows a lot about hondas.

good luck, and also, everything might be working but if the vtec selenoid is not working the ECU wouldn't know that, the ecu only reads voltages from the sensors and according to that it sends the selenoids the voltage to work, so if one selenoid is not working the ECU wouldn't have a clue unles there is a sensor to notify the ECU.
not sure if i make sense, but i don't live in the US and sometimes i have a hard time explaining

i read ya'. thanks. yeah, i'm gonna have to check that wire. any idea what a new solenoid will cost should it need replacing?

The ECU has an internal circuit that watches the voltage of the VTEC solenoid wire. So when the ECU energises the solenoid, it can read the voltage drop from the solenoid coil. When it senses that the voltage is out of range, (such as an open circuit or a short to ground) It turn on the CEL and stores an error code. If the solenoid is all gummed up and stuck, all will look normal but the ECU won't have a clue there is a problem. It also has no way of knowing if there is a mechanical problem with the oil passages.

so, even if i check it with a test light, it could be getting power, just mechanically jacked.. so the light could come on and tell me it's working when it's not. correct? if that were so, then there's really no way to test other than electrical?

You can check the resistance of the solenoid. I don't know the spec. You can also hook a jumper wire from the positive battery terminal to the solenoid wire to see if it clicks.
