I have a 98 ex coupe and vtec isnt working. Where should i start troubleshooting at? Iv searched but alot of the words used are too technical for me so take it easy on me. Thanks for any help.

 

Make sure your vss works, check your oil, and do you have a CEL? Faulty wiring?

 

make sure ur tack works, all wires are hook up correctly oil presuure is good and you have the right ECU<- i seen it happen

 

Make sure you have a Vtec motor . Other than that anything that has to do with oil pressure, rpm, speed, and temperature could affect your vtec. I had some wiring go bad that went to my vehicle speed sensor once.

 

How can i find out that i have a vtec motor? I checked online and it says that the model civic i have has vtec. But on my friends civic that has vtec it says it on the motor and not on my motor.

look for your engine code (in front of motor, near tranny, under dizzy). for a 98 ex, it should be d16y8 which is a vtec motor. How do you know vtec isn't working? with a stock intake, its hard to tell on a single cam.

 

98ex coupes do have vtec.

is your car all stock or has it been modified at all?
does your CEL light come on at all?

And what makes you say your vtec isn't working in the first place???
Are you sure you know how your engine should feel with vtec working?

 

Yes, i know its not working im not that retarded. And i know how vtec sounds, i heard it before on friends cars. Plus my car isnt stock i have a v2 cold air intake, and skunk catback exhaust. Thanks for anymore help

 

no CEL ??
also vtec sounds different on different engines,
it's almost inaudible on sohc engines(urs) and it's very loud/noticeable on integras/dohc engines.

 

which cel are you talking about? sorry if thats a dumb question.

 

with just an intake, your not gonna be able to hear or feel vtec on a sohc. as long as you have so cels, that your vtec is working. make sure your engine is warmed up, enough oil pressure and oil itself,and your going fast enough (ie over 25 mph). I had to put exhaust, intake, header, cam, just to hear my vtec. and i can barely hear it and i dont even feel it

 

A cel is when the check engine light comes on. It will throw a code number. Then you need to figure out what is making the check engine light come on. If it is on, I would recommend taking it to auto zone or oreilys and they will read it for you.

 

why dont you look @ my old vtec thread and see if it helps you, i still have NO VTEC
