VTEC not working

My vetch is not working and I cannot figure it out...it works sometimes, but only when the speedometer decides to work...it also has something to do with my cruise control! I thought that I knew what it was 'cause i unplugged the the vtech plug and blew out with dust off and it worked for 2 days, but no more! Also can this be bad for my engine if I go above 5500 rpm when driving and my vtech does not kick in? Can someone please help me!

do you have enough oil? it shouldent hurt any well none more than it would anyway, and its vtec theres no h

Maybe your phone cord is unplugged :rolleyes: :D

Is your engine light on? How do you know you're not in VTEC? Do you have a SOHC VTEC engine or a DOHC? Sometimes its hard for me to tell when I'm in VTEC on my little SOHC. Perhaps you just don't know you're in VTEC mode. Do you have a VTEC light installed? You might want to look into one of those. If you do a search on Google, you should be able to find instructions.


Once again, its VTEC

Smokie976 has a DOHC

MOst people tend to forget that VTEC works off of oil pressure and temperature. If your car is not warmed up properly and not reaching optimal temperature VTEC will not work. Also if you have low oil oil pressure will not open up the lobes for VTEC to work.

You also could have burned out your VTEC solenoid. But check your oil first.

So if the solenoid is burned out...do you know how much one costs?
I will check my oil, but I do not think that it is that because my speedometer is not working either....it works sometimes and then so does my VTEC!

get an oil change...buddy w/ a 2000 itr, an it wasn't kicking as hard cuz he was a couple months overdue on an oil-change. changed it...s'all good now.

Oh yeah, your blinker fluid could be low, too. While your at it, check the muffler bearing, but to get to it you'll need a wood stretcher. LOL!!

:hehehe: be nice now...the oil change is a serious tip...

Yeah, I know, just trying to get a laugh out of you guys! I didn't know so much went into the VTEC process. I love learning about this shit!

heh, check out www.templeofvtec.com to learn the entire process of it...

Sorry man, that site no longer exists.....

whoops, try this instead: http://www.vtec.net/

Well if your speedo is not working it could be a fuse or loose connection. I would just take it to a dealer.

Thanks guys I will check all of that, but about the oil......my vtec has not been working for a while and I have changed my oil a couple of times since it has not worked and it still does not.....so I guess that it is the solenoid.....how much is that?

If your speedo isn't working than most likely you need a new speed sensor (located on tranny). For the Vtec take a 12 volt source and touch the wire coming off the VTEC soleniod and see if you hear a click, if it's clicks it's working fine ( do this with motor off).

thanks man I will try that...so is a 12 volt a lantern battery? I think that I am just going to take it to the shoop to find out what is wrong with it!

Check your other thread.

Where is the VTEC solenoid located? Anyone have pics?

Edit: Sorry for bringing up such an old thread, I did a search.

hey man here's what I think you problem is...I had a problem with my speedo not working and the connector (sensor) had corroded. After that replace speedo and everything worked...just a htought

Jesus, talk about reviving an old thread.

nvm..took me 3 minutes to find it under my hood. lol. yeah sorry about reviving it..i was searching and this was like the top result.
