hey guys! when i go about reving to 6000 rpm the VTEC doesn't always engage.. I do know of the temperature issue, and this is done after engine is warm enough.

Do you guys know what the problem could be?? thanks guys

 

Maybe not enough oil or your not hitting the gas hard enough.

 

yeah i just had the oil problem. i havent had a chance to test it yet but im sure thats what it was

 

ah yeah that easy! ill go check that out in a few!

 

yea there are really not too many reasons why vtec won't engage.

1) engine is too cold
2) not enough oil pressure
3) not WOT (or close right?)
4) solenoid is not connected.

thats pretty much it lol.

 

^ Not exactly.
I can almost say that I have more experience with why vtec is not working then anyone else on this board. If its not your oil level then once you hit 6000 you are either going into vtec or it will throw a dtc p1259

 

That is a pretty bold claim. Lol, oil level is the definatly the first thing you want to check. AP1s especially burn oil, so you need to keep on top of that.

check the oil and im toped off.. ill go try it again.. hit the throttle hard.. thanks for the info guys!

 

 

I had this problem before; Its usually the temp. or low oil!!

Definitely check the oil!!
