Speedo @ Zero

[|N|]

as most of u know... a mate of mine is doing a conversion on EK with a b16a2... and its almost completed..

but somehow the speedo is staying at zero.. but all the other things work .. like fuel ... rev... all that... any idea?? and vtec also doesnt engage as well...

VSS???

speed sensor on the g/box?

[destrukshn]

btw, do a ECU check.
lol.

[BlitZ]

is it plugged in.. check the conneciton to the sensor first..

then ECU then VSS

it should also throw a VSS service light.

If it is plugged in,check u got 12V(ign on) across the black & black/yellow?(your black/yellow might be diff colour but the black should be the same).

The 3rd wire check if its continuous back to the speedo & ecu
C18 OBD2A
C23 OBD2B

And yes no VTEC till VSS input above 30kph

doesnt vss run a 5v ref,

and signal 0v ---> 5v ---> 0v ---->5v as the wheels turn.

Nick check the ECU as people have mentioned to you here

Fairly sure they are all 12v,I know my B18c is & the B16a1 is.

B18c- 0V>10V>0V>10V......
B16a1- 0V>5V>0V>5V.........

meh i ask stupid question. of course you let the car warm up.

maybe your oil pressure wont let vtec engage?
