My speedometer has recently been going crazy in my 93 civic ex. At first it would jump around from like 0 to 130 back and forth, now it works occasionally but when it doesn't the check engine light comes on. I'm thinking the sensors on the tranny any ideas?

 

I had that same problem a while ago and it turned out to be the speed sensor on the tranny. Change that and you'll be fine.

 

yea it's more than likely your speed sensor...and it'a AWOL (absent with out leave) laters.

 

There should also be an ALT/VSS fuse under your dash. I would check that too.
