I am guessing it uses the ABS wheel speed sensors. Judging from the videos on YouTube, the speedometer itself is more likely the problem. I am not an expert on those however, but you might watch a video and see if that sounds like the problem you are having.

No, it doesn't use the ABS sensors. It uses a sending unit in the tailpiece of the transmission. The speedo is electronic, there are no "gears" other than for the odometer portion of it. How are the rest of the gauges and indicators in the cluster?

thanks for the replies. the problem lies with the speedometer and odometer. everything else works fine. i was hoping it wasnt the gears inside the speedometer , but it seems to keep pointing to that direction since these cars are notorious for the gears wearing down over time. car has 125,000 miles . i was hoping it was an easier fix , rather than taking apart the dash . i guess i was hoping there was a way to test the sensor to see if it was bad
