its a 96 civic with jdm h22a. AND THE DAMN VTEC IS NOT KICKIN IN!!! this just now started happening today. someone told me to replace the screen and gasket inside th vtec syloniod but i would like some more references b4 i start gettin into a money pit. Respond asap plz!!!!

 

add a turbo turbo then your vtech will pop lol hard! i wish i could help you, all i no is it works off oil pressure. maybe check your oil pressure and oil lvl?

 

Is your oil level low? Do you have a big dent on your oil pan?

 

Oil level is good, no dents. This only happens very seldom, only wen the car has been runnin for 45+ minutes. Otherwise it kicks in like hell.

 

that is strange when you find out let us no!

 

Are you OBD1 or OBD2? Do you have any CELs?

It seems, one of the first things the ECU takes away when there is a CEL is VTEC

 

its an obd2 car with an obd1 motor and ecu
no CELs i believe

 

Does your radiator fan come on? What harness are you using?

I converted an F22 harness when I did my swap and didn't have the fan switch plugged into the front water neck, because my H22 didn't come with that sensor. I ended up swapping the F22 water neck with the sensor onto it and that did the trick.

I would get a CEL and VTEC would stop working after 20 minutes or so.

 

thats crazy lol this is my first honda and vtech seems to be a pain in the *** for alot of people. iam glad i have not had any problems with mine! (knocks on wood)

 

ya man my fan cuts on as it should. and this only happens very seldom. My best guess is the screen inside the soleniod. but if it was clogged shouldnt it not work all the time??

 

Not sure what a dirty solenoid would do, I haven't run into that problem yet.

How about your speedometer? Does that work all the time? If your VSS is going bad it may cut in and out.

I think the main things that determine VTEC engagement in the ECU are vehicle speed, engine speed, engine temp, oil pressure and ECU running mode, normal or limp.

If any of the sensors reporting to the ECU are malfunctioning, "VTEC don't kick in yo!"

 

Vtech is a phone
Vtec is for your honda

 

lol hahaha thats funny as hell good call man i didnt catch my self doing that.

 

lol i have always noticed people doin that wen most of em have it written on there motor

 

yea man definitely check your vss on da back of da tranny..... if it's malfuctioning ur assed ouut on vtec.... and also check computer for trouble codes 19 and 21... u might have an auto ecu.
