Put new pads and brake lines on. Brakes work great, but light comes on after car starts moving???? Is this one of the wheel sensors?

Most likely one of the sensors is not signaling. Check the connections and clean the sensor faces if they are accessible.

Thanks for the reply.I did an ohm reading on the wheel sensors and this is what i got; LF:0 ohms, RF:1736 ohms, LR:2154 ohms, RR:2138ohms. I think it would be safe to say that the left front is the problem. I'll get a new one tommorrow from GM. I'm curious as to what the new one will read? Any way, Thanks for confirming what i suspected.

Should be around 1200 ohms at the sensor.

WHERE did you connect the ohmmeter? At the sensor; or in the wiring harness somewhere?

When my '92 had the ABS light on, the harness itself was the problem--the sensor was OK, but one of the two wires was broken very close to the sensor connector.

I had to splice in a $24 harness section to fix the problem.

Maxwedge was right, new one ohmed out @ 1214. These were checked @ the sensor. I put the new one on and the light is out. I don't know what's up with the back ones reading so high. Coils in them may be getting weak? If i understand this system correctly, it operates much the same as a stator on a mower, generating electricity. At a lower voltage! At any rate, the car seems to being doing fine and the young lady that it belongs to is happy with it. Thanks agian for the replies!
