The car is a 1991 245SE.

A month or so I was in traffic, in heavy rain, and had to drive through a pretty big puddle. It wouldn't surprise me if it was deep enough to reach the ABS sensor. As I drove through the puddle the ABS light came on. After restarting the car the light is off, but comes back on when the car reaches about 70MPH. I figured some crud got in there, so I took both front sensors out and cleaned them, and stuck a brush in the opening and cleaned the tone rings as well as posible. There were some chunks of rust stuck to one of the sensors, but even after cleaning the light still comes on at 70MPH or so.

What's my next diagnostic step?
