Sonoma ABS warning light



1995 Sonoma, 4.3L, 2wd. ABS light comes on when speedometer hits about 75mph. Light will go/stay off when key is turned off.

Any suggestions??



You probably have a fault with one or more of the wheel speed sensors.


I’ve never played with wheel speed sensors. Is this a job for a real mechanic or can I check/repair it myself? I’ve replaced brake rotors, discs, shoes, calipers- Is there a simple test/check I can do?


If you have to ask, then I suspect that you should take it somewhere, but not some chain store outfit.


Will do. Now, at least, I have something solid to go on. Thanks so much for the assist.
