95 Sub 4WD-ABS Front Wheel Speed Sense

My ABS light poped on last week. So I jumped the connector to get the code and sure enough I get 6 codes!! 25, 21, 26, 27, 23 and 38. They all seem to relate to the front wheel speed sensors. Now it seems unlikely that both those sensors went out at the same time, so I'm looking for a common element. Is there a fuse somewhere just for the fronts? Maybe a connector somewhere that ties them together? Or am I looking at the brain itself not recognizing them anymore?

Any input appreciated, Thanks!!

All codes are for front wheel speed sensors.
Check wiring and connectors and for rust build up on sensors.
Clear codes and see what comes back first.

You were right. I cleared the codes and only the 25 came back. Looks like the left front wheel speed sensor. Makes sense as I had to change the right front wheel senser a couple years ago. Thanks!!

You are welcome.
The code says open circuit .
Check wiring and plug in real close.
Good luck
