Thank you again. I did clean off a lot of black metal filings at the tips of both front sensors . I also got a maximun of 0.4 AC volts (with a normal meter not a scope) when spinning the wheels by hand. Unfortunately, The light still comes on. I noticed that when I accelerate quickly the light comes on at 18 mph. Should I check the rear sensor? And if yes, where would I find the connection under the hood? Should I also check the sensor at the differential for metal filings or is it more difficult? I doubt that this has anything to do with the antilock light but for a few years ago the cruise control got jitttery, the car lunges a little whenever it is engaged. I assume cruise control uses another sensor. Any other ideas would be appreciated to fix the ABS problem.
