SO i have a d16y8 in my 00 civic ex and i have the P2p ecu and my vtec does not engage at all. I havent done an oil change at all and i know there is a small oil pan gasket leak. What should i do first? put fresh clean oil in there? and once that is done could it be the VTEC solenoid? if so how can i check the operation of the solenoid? Whats the next step in the diagnosis process?

I would really appreciate it

Thanks in advanced Chuck

 

One more thing, My oil level is normal

 

Wire the selenoid directly to the battery with the car running and check if is engaging that way.... ( start up the car and then plug the wire) if is engaging replace the oil pressure switch on the vtec and u r good to go..... good luck..

 

DO i need to remove it from the engine? or just unplug it from the wire harness and connect it that way? And how will i know when it is engaged?

 

stupid question but if the v-tec sully was out it would be throwing a code, take it to autozone and have em scan it, whats it gonna hurt...have you tried that yet?

 

NAw not yet just trying to get a list of all possibilities so i can check them all. Thanks for you feed back and for your IGNORANCE

 

No you going to tested on the car..... Another question is that the factory engine and ecu of the car or is a swap??? Is the check engine light coming on once in a while????

 

There is no CEL? because if VTEC doesnt engage on a VTEC ECU then there is a CEL code.

 

Yep. Should be a CEL if it's not working.

OP, how are you sure that your vtec's not engaging? I drove with a y8 for 6 years, and it wasn't ever really noticeable.

If you're sure vtec's not working, and you don't have a CEL, I'd take it to autozone and pull the codes anyway. It could be that your CEL is malfunctioning.

 

yea its possible that the CEL is malfunctioning. But also you can hear VTEC when it engages. The sound of the motor changes.

 

There are no check engine lights, and it it the factory engine and ecu. D16y8 and p2p ecu. I actually am not sure if the vtec isnt working. I was looking for a significant pull from the car like a b16 does. But if a d16 doesnt have a significant rpm gain after 5500 then maybe its just hardly noticeable

 

its just not really noticeable. Just listen to the motor, it should change pitches when it hits VTEC. Thats about all that happens, if VTEC doesnt engage it just doesnt pull at all after like 5500. B16 is just a D16 with a harder pull in VTEC.

 

Why dont you install a vtec light so you know when is engaiging??? i did it on my civic cuz i got the D16z6 with a chiped P28 ecu and they really help when u want to set up your vtec...
