ERROR on speedo cluster

[JMD]

Helllo , new to the forum.
I recently purchesed a 1995 7.3PSD 2wd auto

I have been searching the net for the last few days but have not found the exact same problrm that I am having.

The speedo reads error and pegs to top speed with little movemnt of the truck.I replaced the axle speed sensor ,not it.

I also went through and tried to recalabrate/rest the speedo.
Here is what happens;
ground the PSOM wire
turn key on with rest pushed
let off restet
displays E 080 ,~I can not find the menaing of this code
press sellect
displays 1000CAL ~and the cal is flashing
and that is were I am at

Is the PSOM seperate from the gage cluster.If so will one work from a F150 gas ?

And the truck seems to run fine But I bought it this way ,so I have nothing to compair to.It shifts through all gears and the Over drive off light does not flash.

Thanks in advance
Jeff

I think to speedo in the cluster is the same gas or diesel, I have used a F150 gas speedo for a E250 gas
