ok i have a 93 honda civic dx with a b16 swap in it. i bought the car like this cuz it had some problems one the VTEC is not kicking in there is no check engine light going off or anything! the car has aftermarket cams in it! is it posible that they might not have been hooked up right or it no longer has VTEC because of them? like when it hits VTEC range the car starts smoking white smoke from it getting to much gas! but the valves are not opening or something. im so confused can anyone help me out here??

what ecu do u have

You may just need to clean off your VTEC solenoid. There's a wiring clip and about three bolts that hold it on to the side of your engine... and it should come off without much problem.

Even if that's not the direct cause of your situation, it's a good thing to do, 'cause when you do get your VTEC running, it'll be more responsive and run smoother when you're up there in that rev range.

A vtec light would help right about now lol.
it's very easy to make one.

Do a simple rig with a small light bulb. I think a 192 bulb from checker or autozone. Should work, but if not the bulb type from your gauge cluster should work. Using a small WIRE, vtec is POSITIVE, wire it to the bulb and the other to ground. Bring it to vtec and watch to see if the light comes on. If it does, then the signal is sent :D

And white smoke while in vtec range. Sounds like something is leaking internally.

My old LS/Vtec -all motor did jux that. Turns out to be worn rings.

good luck

Are you f*cking kidding? Cleaning out the solenoid will make it run better in VTEC?!? Someone take this guy's internet away from him.

LOL. Could it be at all possible for the aftermarket cams to be Toda VTEC Killers?

Jas0nEK

Maybe it was a dumb suggestion to make, I dunno ... it hadn't occurred to me that one could, or should, remove the solenoid and clean it out until a few weeks ago I read something about it.

Hell, I don't know if this guy has thought of it or not.

And the fact that it'll be a worthwhile expenditure of time even if it's not actually the problem is just icing on the cake, isn't it?

White smoke is water vapor not to much fuel, that would be black. Oil smoke is blue.

alright i will clean it even though some say its dumb then i will try the light see if it works its possible i could have warn rings cuz its loseing oil i thought it was just leaking!

my vtec on my d16 isnt working either. i clean the screen on the vtec solenoid, which was definatley dirty, but didnt notice any change. im still hunting down the cluprit when i figure it out ill let you know what i find.

97Ej6mike

cleaning a VTEC screen will do absolutely nothing. Look elsewhere for the problem.

EG_fan_59

if the screen is so clogged that it wont allow fluid to pass thru...you bet your behind it will effect vtec.

mikester1222

that would have to be one clogged screen for all that pressure to not push it through

steve.kelloggs

It could be the dog clutch fuse under the hood of your car my vtec was not working and it was the fuse

mikester1222

dog clutch fuse??? never heard of it! but will look it up! where is it and what does it do?

Thank you, I was going to write that at the bottom of the page but I decided to read other posts before I made mine.

Lets sum this up though-

1) Check to see if VTEC is even wired in. On a DX there is no stock VTEC pin on the harness so you have to wire one yourself. Its connector A-4.

2) If the previous owner put a set of cams in, he could have put in TODA VTEC Killer cams in which was stated already in this post. Instead of VTEC engaging at a certain RPM, it is engaged at all times due to larger lobes and no VTEC middle lobe, (from what I understand, correct me if I'm wrong on that.)

3) Check your ECU with a scanning tool because it is possible that someone pulled the CEL bulb, (I've seen that before.)

Hope I helped. Good luck.

What ecu are you using?

EG_fan_59

FIXED! the vtec oil pressure solenoid was just as gunky and clogged up as the spool valve screen was. AND GUESS WHAT, 97EJMIKE, my vtec works now. no oil pressure to push the locking rod through the rocker arms and NO VTEC. so pull that thing apart and see if its dirty and clogged. it fixed my issue for sure. case closed.

mikester1222

VTEC is wired up!
i am running on a p28 ecu
im going to hook a light to my vtec to see if power is going to it tomorrow and i will post you all on that see if its working. then we will go from there!

mikester1222

ok i cleaned the screen was not dirty at all really but then i hooked up a light to it and the light is not lighting up in VTEC range so there is something electrically wrong not mechanically would the speed sensor not working cause it not to work? also it looks like it has a diffrent distributor would this have anything to do with it?

soichiro honda himself came down from the sky and said "joo will have no vtak without vehicle speed sensor signal showing computer vehicle in mot-chin"

so yes, fix that first

EG_fan_59

i think if your vss wasnt working, your tach or your mph gauges wouldnt be working. so if you have that issue its probably the vss.

mikester1222

haha ok ok i will get to a junk yard and get if fixed monday! but it was working before and vtec was not working! so idk i will try it again the guy i bought it off of blew up the battery and got acid on the plug so its messed up! i will post back on monday!

i think its the piston rings also cus thats what happened to mines. vtec didnt hit and white smoke came out..so nasty..and possibly the ecu..

b16_sol_707

+1 for VSS. Vtec is dependant on rpm, oil pressure, vehicle speed and engine load.
