1993 lexus LS 400 speedometer works sometimes

The sensor was changed but that did not help. Sometimes the speedometer works, and sometimes it does not. It will work for a few hours and then stop working.

Hi...the needle assembly at the speedometer is faulty. Because your dash instrument is all electronics with no cables or moving parts attached, your whole instrument needs to be placed....hope this helps.

1992 SC300 Speedometer doesn't read accurately. Can it be calibrated?

No however the speed sensor can be replaced.

A couple of things can throw off the speedo, Tire diamete size, did you go a size up? this will make the speed show slower that you are actually moving. If you did, then it's working correctly. you will just have to make a mental note of the change or go back to the original size.
