Speedo sits at 125
This is an old thread, but it has the best pictures of the likely problem part.
A few months after buying my 89 5-spd, the speedo pegged to 125 while I was driving it. A couple days later it worked fine, then went out again while driving it. Now is just pegs to 125 at start up and sits there.
I have already had the IC out for previous issues and I'm confident all the connections are good. The odometer is still working as well, or at least it is still turning and seems accurate for the mileage I have driven since the problem, which is very low. Overall the car has 70K miles, no rust, and is very clean.
My best guess is the speed sensor has gone bad. I have found the replacement sensor at Rock Auto. I'm wondering how hard it is to change out, and how I get at the sensor. I am not a mechanic, but willing to learn and give it shot before taking it in to my local shop. I'm also wondering what the likelihood is that the plastic gear inside the trans is the problem. That would probably be a real pain to fix.
Given I won't be driving the car much until spring, I have time to sort this out. It's no fun to drive without a speedo. The GPS readout on my traffic app keeps me out of trouble, but it's just not right to look down at an unmoving speedo.
Thx,
