The speedometer in my 99 RX300 has stopped working. The needle does not move at all. I assume it is speed sensor related but I don't know where that is located.
Is this a good question?

Have the OBDII code read to see if there is a code . speed sensor failure will always throw a code . Check to see if the odometeris still working . If it is then the instrumentation panel is defective . A used panel from the auto wreckers will do the ECM will reset your mileage once installed . The parts on the instrumentation cluster are not really interchangeable you will need a whole unite and they tend to be pricey from new. if you do get a p0500 or p0501 are the usual codes depending on your car there can be an input and an output sensor . Even if only one is showing replace both if you dont you probably will have a failure on the second within days of replacing the first one . Hope this helps

Dan " don't know where that is located." there are two. You need to remove the air box to get at them. One sits at a 45-degree angle facing the battery, the other sits horizontal and is directly below the air box. Remove the 12mm bolt, then lift and twist to remove the sensor.

first thing to consider doing would be to use a scan tool to see if the speed sensor signal is available if it is available there the problem would not be with the sensor but wiring ,network or cluster it is unlikely that just the instrument is bad and or replaceable as a part currently this area is only serviced as a unit

Replace the odometer on the dashboard.

This video explains the 3 symptoms and shows the process of how this might be fixed. Hope this helps everyone who may run into this issue.
3 issues are:
speedometer not moving
odometer digital display is blank
shifting is erratic while trying to accelerate
I had this same problem sometime ago in 2018. Both the speedometer and the odometer were not working. The cause of the problem was that the 12mm bolt used to fasten the speed sensor was broken so there was not enough contact.
After the broken bolt was removed and replaced, everything started working perfectly to this day.
Check if the sensors are correctly fastened. If they are, have them removed and cleaned. Replace them. If the problem persist, it means the sensors are bad and need to be replaced.

I have the same problem, 02 Lexus RX 300 AWD Codes read 0500 Speed sensors replaced both.
Still not working, what are other options? Is there a Fuse or Relay connected to any of this?
