Ok heres the deal my vtec isnt engaging at all. i know its wired up right, but heres the thing my vtec is suppose to engage at 4500 rpm and when it reaches it the check light comes on. idk if the solenoid is acually bad or the oil pressure switch needs to be replaced. please help any advice will do.

 

Car? Engine? OBD? All of these would be good things to include in your post. Also turn your rep on.

 

changed oil today

 

then check the ECU and make sure all the wiring is connected

 

What ecu? Chipped?

Try another ECU if possible.

edit- what NasT said too. Post wasn't there when i replied.

 

i know its wired right at one point the check light stayed all the time so i had a friend check the codes and it was the vtec so he found that the wires were cut somehow so he wired it back up and the code went away but when i try to go into vtec it comes back on until i turn it off and start it back up

 

sounds like same issue.

I doubt he randomly has a certain year range ECU that doesn't work with a certain type transistor, that actually has said transistor installed.

Pull the code and see what the fuck it says, it sounds like the pressure switch since it only comes on when you go to cross over.

 

wow makes alot of sense thanks for the link man

 

Kind of confused by this lol.

It has nothing to do with the ecu, but the mod that was done to the ecu from my understanding. In that thread (and many others that I've seen) the Chipped ECU that guy bought had the wrong transistor installed.

I was talking about using a stock ECU for that engine in case he was using a chipped one and it was fucked up.

OP never said what egine/ecu/etc etc he had. So it's possible.
