[go fast d-series]

wazzup everyone.
i've some q's
i've a 96 civic dx with a d16y5 engine.
my prob is that the vtec doesn't work.
what could be the prob?
my mph gauge doesn't work, could that be the prob at the time?????if no what can i do?

is there a check engine light? if the speedo isnt working the ecu isnt reading vehicle speed and vtec will not work

yeah your spedo needs to work for vtec to work.
plus the y5 is a vtec-e, not regular vtec

 

[BryanK20]

so you have a DX with an HX swap? what ecu are you using? and yes, the speedo MUST work for vtec to engage. try replacing the VSS and see if that helps

i hate VSS!!!

 

[singlecizam]

i hate VSS!!!

it can be dissabled in crome so that it doesn't require the vss to engaged vtec

For me, when my speedo quit, it was a matter of changing a bad fuse.

I assume you have the correct ecu .. dx ecu won't run VTEC
