Speedometer problem

What year is that Olds Rengency?

@Joey198687Heller It's a 1989. Still going, though I'm not the one driving it. Almost 200,000 miles.

No trust me VSS won't always throw a code. I just replaced this on my '85 Park Avenue.

Your vehicle speed sensor. $10 at the junk yard.

Thanks for the tip, but no.  The odometer still works properly and there is no "check engine" light as on another car I had with bad VSS once.
