i bought a 98 honda civic coupe when i got it the speedometer was not working. it reads everything like the feul and the rpms the mileage is stuck and the mph doesnt work. i ran CEL on it code came up for the speed sensor. the check engine light went off but the speedometer still doesnt work. any ideas how to fix this problem.

get a new sensor(i forgot what the sensor is called) but i know its on you tranny somewhere. i want to say its called vss, dont quote me though.

it is called vss and it's located on top of the tranny.

Theres two things that can cause this. First thing i would do is locate the vehicle speed sensor (vss) and make sure the plug from the engine harness is plugged in. Most likely the sensor went out and you need to replace it. I dout that theres a problem with your cluster.

remove the VSS (speed sensor) on top of the tranny in the back right. Its one 10mm bolt and take it off. Replace it with any other one from a single cam or dual cam, etc and check the harness plug that plugs into the sensor to see if its damaged or not. Put it back in and bam. You should be good

thank you for clearing that up for me.

i did replace the vss i got a brand new one put it in and it didnt work i made sure the wiring harness was also plugged in. has to be the cluster right ?

i have the same issue, but i did an obd1 swap into my 98 hatchback. i was told, well i read on the internet somewhere about this issue with the VSS sensor. i swapped out to my third cluster. swapped out VSS sensors twice and nothing happened! didn't fix the problem! before the swap, everything was in working order...checked all the plugs to make sure they were connected and they were...

they said to check voltage at the plug...i didn't do that cause i don't have a voltage tester...

swapped tranny cause i thought it was a bad tranny...nothing!

anyways...read somewhere on line in the web world that the wiring is probably rubbing up against the intake manifold that is why the VSS isn't working

check behind/under the intake manifold to see if you have uncovered wiring touching the manifold...if so ziptie that away from the manifold...

good luck...i know it is sort of confusing of what i typed...confusing myself...but yea...

lol aight i will try everything i possibly can to get this problem fixed. yea just check all the wires everything is getting power it has to be the cluster.

Hey ek4_b16a: Did tieing off the wiring bundles under the manifold fix your speedometer? What I've read says that failure mode generally triggered the check engine light and/or burned a fuse. Did you have CEL and/or blown fuse symptom or did this fix your speedo even though you didn't have those symptoms?

RioSmAn: Does your speedo just stay on zero, or is it intermittent...occasionally coming to life for short bursts, but quivering and jerking before it goes back to sleep on zero? I have this intermittent behavior on mine. I tried replaceing VSS sensor (just the above-tranny-case portion, because lower stem is only mechanical and it all looked good and because when I pulled it I could see no wear on driven gear and the differential gear that drives it in the tranny was turning & looked to be fine). VSS replacement didn't work, but it was a VSS from junk yard so not 100% sure it works. Then I replaced cluster w/ one from junkyard (again not 100% sure it works), but speedo behavior didn't change.

I've been through the Honda service manual to follow debug flowchart on page 23-140/141 (Speedo/Trip Meter/Odometer Troubleshooting). Everything is OK until I get to the step that says check the voltage on the VSS connector YELLOW/WHITE pin to see it is "APPROX 5V OR MORE". Mine gets 4.7 V. Is that "approx 5V"? I don't know. Anybody else out there w/ a working speedo on a 92-95 Civic, could you disconnect your speedo sensor and measure voltage between yellow/white and body ground and tell us what you get???

RioSmAn

that is what mine does it will come to life at weird times when i am making a left hand turn and rev my rpms a little higher then nomal while i am shifting that is when it will kick on. someone was telling me they had this problem to they replaced the cluster the engine light went away and the speedo just started working. this problem is so annoying

ek4_b16a

no it didn't work...i just rechecked my jumper harness and looks to me like none of the wiring were done correctly...so i'm waiting to use a buddy of mines jumper harness to see if it is just that...been driving around without a working speedo...so yea...will keep you posted...if you get yours working, lmk what you did too!

RioSmAn

going to replace the cluster tomorrow we will see if that is the problem i hope so. so i can stop spending money on this stupid problem.

are any of the prongs on the vss broken???????

when mine went out i pulled the vss out and looked at the plug in and my center prong was broken.....

RioSmAn

no i check the vss there is nothing wrong with it i bought a brand new one problem is still there i am going to get a cluster and see if this fixs my problem if not i have a new cluster is there any way i could check the wires or something. i no there is a lose plug under the intake mainfold and a wire that looks hacked up or something could this play a part in my problem???
