i have a 91 hatch with a b16, my speedo cable broke, ever since my speedo cable broke my vtec doesnt work, is there any relation

 

Yes,

VTEC requires temp, oil, and speed greater than 30 mph.

 

so when my speedo cable comes in my vtec will work

Yes. Your check engine light should be on and throwing the VSS code.

The CEL "should' be on. However, I had a code 17 and my CEL wasn't on so who knows.

 

hi guys..im new here..i have a 91 crx si with a b16..my speedo doesnt work..so does it mean vtec is not workin?

 

Yes if your ecu is showing a code 17 then VTEC is not working.

VTEC needs three inputs to work.

Coolant temp
Oil pressure
Speed above (i think) 30mph

 

thanks for the info..i have a couple more questions..it doesnt show check engine light, i havent checked my ecu.i will check it 2morrow what if its not throwin a code?should i still worry? and some1 told me this problem is only on 0bd-1 cars..mine is obd-0..is this true or is this problem for all b16s? thank u again,i appreciate it

 

i have a 1st gen b16 and when my speedo snaped i got a check engine light and no vtec, fixed the cable and everything is fine

 

well i checked my ecu today..its not throwin n e code and i have no check engine light. and my speedo still not working..even if im not gettin a code,do i still have no vtec? thanks guys,i appreciate it

 

if you can't hear a change in the exhaust note after 5200rpms than no you vtec is not working.

if the speedo doesn't work it shouldn't work.
