abs light on at high speed

[auga22]

When i am driving at high speed (about 120 kmhr,70 mi.hr) the ABS light and the Brake light both come on on the indicator panel. To reset them, I have to stop the car completely. A speed sensor have been changed on the right rear wheel with no fix. Can anybody come with a suggestion?

What year vibe?Sometimes the brake light comes on when the fluid is low or dirty. Check to make sure it's full and looks clean (not dark or contaminated).Anything else would probably require a diagnosis of the ABS system.

I've seen that sort of thing in other vehicles with ABS.The computer says it's one sensor, when in reality (in a couple of cases anyways, one GM, one Honda), the problem was the other 3 (yes THREE) sensors!Not 100% sure how the Vibe is set up as far as the sensing ring/teeth goes, but you might do good to take all 4 wheels off, get in there with some brake cleaner and spray down the ring/sensor areas on all 4 corners, if that's even possible on the Vibe. Heck, relatively easy and cheap if it fixes the problem.

Try rotating your tires. If the fronts have too much of a difference in wear compared to the rears, the high speed may make the computer think that something is way off because of the difference in rotational speed.
