Speedometer comes on and off?

[Lil cb7 Sedan]

So my speedometer work sometimes but most of the time it doesn't work. What's the first think I should check?

Vss or vehicle speed sensor

vss and vehicle speed sensor are the same thing

[roland lorenzo]

For sure it would be the speedometer sensor.

Yup if your miles don't turn over as well it's the vss

[Lil cb7 Sedan]

The miles still turn over. So where is the vss located?

on the transmission directly below the throttle body. youll see a 3 wire plug going to it. Id first suggest cleaning the terminals with some electronics cleaner. Ive had issues with all three of my CB's and cleaning the terminals helped most of the time.

Thanks for the tips guys

I think if that's your problem, you should get an expert to check it.

Why? The speedo sensor is very easy to diagnose. No need to waste money on a mechanic

In my case, I have my friend who's expert in automotive. Just my suggestion

You can pick them up used very cheap as well. I just bought one from a pick n pull a few days ago for 10 bucks. Threw it in in the parking lot and drove home with a working speedometer and odometer

When i replaced mine I bought it from O'Reilly's and it was like a hundred and fifty bucks. The junkyard one might be a better option.

You're all correct, but this newbie hasn't a clue to what or where it is. Yet he don't need us to tell him where it is and what.
If you would have done a simple search..on this site alone are numerous post explaining this part. Google it and more come up. If you are even slightly mechanical it is easy after the read. Good luck
