I just bout a 83 cutlass supreme and my it dont tell me my speed, like it dont move at all. Is it the sensor or i need a new cable?

check out your fuse and see if any of them burnt out first if not then problly a sensor under the hood or its the wires also try hitting the dash idk might work i had a car once that the dash lights wont fully come on till i hit the dash also the harness might not be in all the way theres alot more reasons

Probably a bad speedometer cable, i don't think its a fuse or sensor cuttyz dont have them.

Speedometers are over rated...just go wit the flow of traffic!!

lol x2

I had that same problem bruh when i first got my 86 monte. my cable had broke but i didnt know it. i got this basehead that fixed on cars in the hood to check it out for me!! we went to O rileys and bought a cable for like $20 if even that!! but the problem we ran across was finding the right cable for the motor that i had, O rileys where tryin to sell me the cable for the 305 motor that came stock in the car. it was a 454 that came out of a suburban and i didnt know the year of it was so i had to guess around until we got the right cable! Hope this helps

Wouldnt the cable for the speed be on the transmission??

yea thats where it was but we changed trannies to so i didnt have a stock tranny

just roll down ur window and scream out "HOW FAST ARE YOU GOING?" to a nearby vehicle in motions.

get a kenwood navi deck and it tells you your speed on the screen... problem solved
