Hey everyone you've got a great group here and i'm hoping someone can
give me a hand.

I've got a RABS light on in my 92 Explorer EB. And when I checked the
code readout I got code 9. This tells me that I have a high sensor
resistance. Well I took the speed sensor out of the rear axle housing
and measured it and got 1.5 Kohms on it which is too high so I
replaced it. The problem now though, is that my RABS light is still
turning on and it is still indicating that I have a high sensor
resistance. I'm stumped as to what the problem might be now. Does
anyone have any ideas???

Maybe you just need to clear the codes and see if it comes back.

When does the light come on? When you turn the key does it come on
right away, does it not come on till you brake normally, or does it
only come on when you brake hard? What you might try as a diagnostic
is to unplug the connector and short the terminals together so it
should sense a low resistance and see if you then get a code 10 to at
least verify that the wires are good all the way back to the
connector. If that still gives you a code 9 you must have a break in
the wire harness somewhere.
