speedometer stopped working , but the OBD port shows the speed sensor works (1 Viewer)

[tdale1316]

Hey need some help,ON My 2005 with 300K the speedometer stopped working this morning. I noticed when i cranked the truck early today the RPM gauged lagged for a few seconds then worked fine. As I started down the road I noticed the Speedo pegged at 0?
Took it to work plugged in OBD scanner and drove around the speed sensor showed the speed he computer,
But the Speedometer in the cluster was still at zero?
Things I checked so far?
Alternator is 14volts
Checked both gauge clusters fuses in kick panel they were good 10 amps both good,
Any tips on what to do next
Can you guys help?
Should I pull the cluster and maybe try to clean the contacts ?

Any help is greatly appreciated

Not sure whether your OBD scanner is looking at wheel speed sensors (used by ABS etc) or vehicle speed sensor (used by speedometer in instrument cluster)?

The visuals in the video at this link may give a few ideas where to look:

Installed the Lutz Auto Speedo Calibration on my LX470

This install was/is pretty straightforward, truly plug-n-play. There's this ridge on the Lutz connector that should have been trimmed off before it was shipped to me but Bryan from Lutz is quick to reply and told me that he was sorry about that, it should've have been shaved off prior to being...

Also suggest have a look at diagrams and check harness, connectors and sensors at:

Could be a stepper motor inside of instrument cluster that went out. One of my LX's has had this issue occur very intermittently for a couple years so I assume one day it will die for good.

@IndroCruise thank you so much for the link, when I pull the drop down I can't find the Speed Sensor, I am an old man LOL , Any way now the cluster is lagging at start up everything pegs to zero for about the first 3-9 seconds meanwhile the speedo barely pulses for a few seconds then nothing. I guess I will order a speed sensor this weekend for it and try that route, I left the battery disconnected for a week to see if it might fix itself. No Luck, thanks again

The pic below shows the location in the FSM of the reference to the Vehicle Speed Sensor -- and the full FSM article also is attached further below for convenience.

As mentioned above by @Flipped Bezel, the "stepper motors" within the instrument cluster also need to be considered. One of these small motors drives each instrument, including the speedo. Best to search IH8MUD. For example, this thread gives the idea:

2004 Land Cruiser Gauge Cluster FIXED! How-To

I had an issue that a number of others are experiencing with their 100 series. Four out of six of my gauges worked only about 10% of the time. The rest of the time they were just dead. Research led me to believe that my stepper motors needed replacing. These are little "tomb-shaped" (black in...

This is my guess as well. If the truck is reading accurate speed but is not showing in the cluster, odds are the motors are burning out. The speedo may come back here and there, but it will eventually just die. I've had this going on for about 2 years in my 05 as well. I thought the speedo had finally died but it surprised me this week by working 3-4 days. A rebuild from Tanin Auto electric will run you about $700.
