okie i have a 94 civic cx with si cluster.. the rpm works fine but the mPh won't work.. it used to work but all the sudden it just stop.. the odometer and fuel mileage won't work either.... what can be wrong with it.. i don't have a check engine light.. i replace the cluster, vSs like 10000 times.... my SRS light stay on.. does that have anything to do with it?? i checked my wiring and the only wire that got cut was B10 which is for Vss.. but i wired it up so it should fine...

i have a h22a1 swap in my hatch just in case that might help someone....

 

Just check your wiring,I had a problem on my h22 coupe with my speedo not working,I changed cluster and nothing same problem,than saw that the connector plug on the vss was kinda burned and a lil correded.Wired up the pins directly for now and bam problem solved..

 

you wire it directly to the ecu??

 

oh nah,I dipinned the vss connector plug from the wiring harness and connected each pin directly to the pins coming out of the vss to make direct contact since my connector was bad..its just something temporary til I get a new vss connector plug...

 

i tried to do that but it didn't work either.. my srs blink when i check for engine code?? does that have to do anything with it??

 

bump need to ref my car

 

does the vtec have anything to with this??
i haven't tooken my car to vtec because i am scare my timing might slip again, but i don't get a check engine light for my vtec.. i hread somewhere on the net that if your vtec isn't working properly the speedodometer won't work??

 

okie got the srs light gone.. i did that srs light dissappear trick..hahaha.. but speedodometer still won't work.. hrm.. no check engine light code except for EGR.. (i need help on that) i changed cluster again and nothing.. hrm.. anybody??

 

i got NO VTEC AND SPEEDO isnt working.. no check engine light for both... i double check the wiring and everything looks good.. why won't vtec work?? anyone wanna help.. COME ON honda TECH...

 

anyone wanna help out here

 

did you check all your fuses.. I remember is a buddies civic.. he had a fuse blow and the speedo stoped working.

shot us an update on things you have done.

 

things i have done.. check all fuse no.24 fuse srs and agg fuses.. nothing blown... check all my wiring to vss.. all wires are connected... i rewire my egr and intake control solenoid and evap purge directly to the ecu

EGR contro lifel 3 wires
left wire=wht/blk= d12
middle wire=grn/wht=d22
right wire=red/wht=d20

EGR lift=2 WIRE
left wire=blk/yel=A25
right=RED=A11

ECT wire-2 WIRE
i forgot but when i go back and look at it will let you know what wire i tap it into

intake bypass solenoid
yel-BLK= A25
the other wire which is the signal wire=A17

VTEC
grn/WHT = A4

blk/blu=D6

Black wire to GROUND WITH ENGINE HARNESS

 

try wiring the 3 wires from the speedo sensor directly to the ecu. Just like you did with these other sensors.?

Just looking to help.

 

i wire the speed sensor directly to the ecu but nothing so i wire it back to the engine harness
