Good chance its an oil pressure if it only comes on when it comes on when it hits vtec. Get the code though and that will tell us for sure.

Re: check engine light on when V-tec engages (Chiovnidca)

Sounds like the VTEC oil pressure switch. Do you have a V-AFC?

Re: check engine light on when V-tec engages (satan_srv)

no i don't have V-afc
i checked it by looping the terminals at the passanger side of the car with a paper clip... o o o like that? did i do it right? then i put it to the on position.

no engine light.
my check engine light only goes on when i vtec it in 3rd gear then if i shut the engine off and turn it back on, it's gone

Jump the 2-pin connector, that should work a little better.
