vtec not working??

How do you know your VTEC is not working?

RE: vtec not working??
 

put oil in ur car. when ur honda gets low on oil the v-tec will not engage. trust me. my sohc did the same. i thought it was a vtec senaoild and it wasn't. by the tim ei found out it was too late. the with the heat these days u are bound ot be below 2 quarts and if ur blew 2 quarts it will not work.

U'd probably get better feedback, if u posted this in the engine forum. There r some very knowledgable people that help out there.

RE: vtec not working??
 

did you put your rpms up high enough so vtec will kick in? i think its 5800 rpms, if not that then it could be the selanoid.

Hey Daisoman how did you get that name? I used to do business translation with a huge 100 yen (dollar store) chain over in Japan called DAISO. Daiso is probably one of the funniest places in Japan because they literally have everything you could think of for only 100 yen! Let me know!

Are you saying this because you can't hear it? Or you know it's actually not working?

RE: vtec not working??
 

ok ive had the car since January and changed the oil twice.... i didnt really even know what vtec was until i drove my friends Sir then felt and heard it... he drove mine and said my vtec doesnt work... i have redlined it but still nothing. would it be the ECU because thats what i was told it could be the problem? and do u guys think this is going to be expensive? thanks!

RE: vtec not working??
 

If you redlined it, it should mean its working? What ECU are you using?

RE: vtec not working??
 

what engine........are you sure it even still has a vtec engine? also is the check engine light on and if so have you checked the codes? theres a few things that will not allow vtec to engage.

RE: vtec not working??
 

ya i redlined it and still noting thats why im posting my problem.... im positive it is a b16a2 as i have seen the code on the actual engine... plus it says DOHC V tec right on the engine

dude o dont think you vtec isnt working, in the past day i had that problem too and i finally solve it and was just my imagination. first you have to wait your car to warm up.. is your car Manua trasmision??? if no well you wont hear vtec activation in neutral but it kick in neutras. if is manua well i dont recment to try it on first gear so when on second push the gas as deep as posible and listen for changes in the sound like about 4,800 or above, remember turn off the A/C and with hte windows closes you will hear it better. of you dont notice change that i really doubt becasue you engine has a really really loud vtec sound well put and intake and you should hear it louder, if no well install the vtec ligth .. i do it and it work and i have a weak d16z6 soch vtec

Vtec kicks in at 5500 on the B16a2. If your ecu is not letting you hit vtec it will limit it at 5K I beleive, so you wouldent be able to hit redline. What mods do you have???

RE: vtec not working??
 

the rpms just climb to almost 8000 without NO Vtec im telling you guys there is not vtec... i bought the car like this... could it be the previous owner did something or blew something
