Ls400 Speedometer Reads -30 Mph


Recommended Posts


The car is a '91 ls400 that is generally in excellant shape. However - the speedometer is pinned at -30 mph. It shows a very small tick when moving at 55 or 60. The tach and odometer all work. The trip meter works, but does not read tens of a mile, only miles.

Has any one seen this?

Does anyone know the cause?

Is this a unit replacement or can it be repaired?

Thanks in advance - Dan
