Vtec solenoid testing?
 

Well, after all of the ---- I have put up with on this car lately I thought I finally had it. I finished the mini-me, I fixed little problems here and there, and I got the timing fixed so the car actually ran worth a ----.

Now.....Vtec isn't engaging. I have it wired through a solenoid in my car like this:

And that solenoid clicks over just like it should. I just don't think the Vtec solenoid is clicking over on the head. Is there any way for me to test the solenoid?

run a toggle swithch to it click it on get rough rough idle solenoid works

Re: Vtec solenoid testing?
 

I've already got the solenoid pulled off the head. If I just run a wire from the battery to the grayish plug with one pin should that turn the vtec solenoid over?

Re: Vtec solenoid testing?
 

You will also need to ground the solenoid, but yes that should kick it on.

Re: Vtec solenoid testing?
 

ground which pin? I think we may have just found my real problem!!!! :)

Re: Vtec solenoid testing?
 

Its a solenoid. Just use an Ohm meter!

Re: Vtec solenoid testing?
 

there's no ground on the vtack solenoid ;)

if the solenoid pops when you touch the wire straight to a 12v source, then that means the solenoid is good, now the question is if the ecu is sending 12v to the solenoid when it's suppose to. are you running a chipped ecu? obd0 or obd1? hook a 12v led up to the ecu, put the positive wire on the vtec pin out, and the negative on a ground, then drive the car, if the led lights up when you should hit vtec, that means the ecu is functioning properly also.

I know there isn't a ground pin on a vtec solenoid, just one wire for power to activate it. But I thought it was grounded through the body of the solenoid. How can you activate it with no ground? That's like connecting only the positive end of a battery to a light bulb and having it turn on. Am I missing something here?

Re: Vtec solenoid testing?
 

Well, throwing 12V+ at it doesn't do anything to it so I'll assume it is bad.
And yes, I know for a fact that it isn't the ECU. I'm running a xenocron chipped PM6 w/ TurboEDIT 1-wire Vtec. My maps have been properly hex edited as per gimpyaccord/splittime's instructions on PGMFI to get 1-wire vtec to work. :) I still may test with the led though. :)

toggle switch old school ghetto vtec

Re: Vtec solenoid testing?
 

That has nothing to do with my question

Re: Vtec solenoid testing?
 

It's bolted to the grounded engine.

did u pull the oil limiter out of the block or run a oul line to the solenoid if u dont have enough oil presure it wont crosover in to vtec

Re: Vtec solenoid testing?
 

yes I pulled the oil jet out of the block.

Re: Vtec solenoid testing?
 

dumb question but is ur spedo working vtec wont kick with out a spedo

Re: Vtec solenoid testing?
 

yes, the speedo is working. I already have taken the solenoid off the head and tested it. It is shot.

Re: Vtec solenoid testing?
 

oh bad ass well do u need one i have a cupple lieing arround

Re: Vtec solenoid testing?
 

Actually my car went into vtec and the speedo don't work. Though once I got a CEL for the o2 sensor then it wouldn't kick over.
