I'm having issues with my speedometer/odometer on my trusty daily driver.
93 civic 1.5 SOHC DX

It's really weird b/c 90% of the time it hasn't been working. The few times it does work, I've noticed have been when there's a lot of moisture in the air (raining or really humid). When it's working, the speed is dead on and it is registering the right speed (or no speed at all when not work).

I haven't been able to figure out if this is common in a non-functioning speed sensor... or if mine is still working.

I've tried unhooking it and cleaning the contacts w/ rubbing alcohol, but that didn't do anything. Any ideas?

Also, if I have to replace the speed sensor, are there any issues with buying one of the cheapies on ebay? ($25 shipped) Or do I need OEM... can I save some bucks and hit up an autozone?

No it doesn't have to be oem you can even go pull one from the junkyard just make sure its from the same tranny (auto or manual).

 

alrighty then... i'll get a cheapo from ebay

but you think it's the speed sensor and not something else?

 

Ok... so I changed out the speed sensor, cleaned the contacts and even lubed up the where the little pin goes into the transmission with WD-40.

Still not working.

I need help guys.
What else could this be? Where do I even start?!?

 

it could be a short but usually the speedo will jump around quit a bit if thats the case.

 

i am PRAYING it isn't electrical...

It doesn't really jump, i mean it usually won't work, but sometimes it will. I guess it jumps to the proper speed when it comes to life.

I've found it is more likely to work when it is wet out, or if I am going 80+
but even then it is rare

 

Nobody has any help for me??

I got pulled over today and tried to use the "my speedo just stopped work" line (which is true in this case)

i got my speeding ticket + a ticket for a non-functioning speedometer, which i can get dropped if i have it fixed.
i guess i can go have a shop write something up for me, but i'd really rather get it fixed.

please help!?!?

 

Did you get a new unit? have you ever checked the connections at the cluster? Does any of the wiring on your car look hacked? Or the vss wire look hacked?
