Anti-Lock warning light

I have a 2001 Buick Century and today I took the car out and while driving I notice the Anti-lock warning light was on, the brakes seem to work alright so is everything else. Is this pretty expensive to fix? Appreciate your help. Thanks

Yellow light only???? No red brake warning?....

If it is only the yellow, Then The ABS system has detected a problem and disabled the "Anti-Lock" function.....Conventional service brakes are still fully functional....No need to worry just yet....

Now to answer your question......MAYBE...

The wheel speed sensors are a common failure point on GM "A" bodies..Century , Ciera, And many of the Malibus. The wheel speed sensor is an Integral part of the Wheel Hub and bearing assembly and must be changed as a unit.....A Repair shop and a Scantool will be necessary to verify this , and also to determine which side of the vehicle is affected...Left or right, front or rear....

By no means will I tell you to Ignore it, but There really isnt an Immediate danger or hazard at the moment....
