Weird thing happened today

[ThirdgenTa]

03 Regal GS.
Was driving down the road and coming to a stop. Halfway to the stop I felt a weird bump in the brake pedal and my ABS light, Traction control and Check engine light went on. They stayed on until I got to my destination 2 miles later and I parked and shut it off. I started it up and they didn't come back on.
Anybody know what's going on here?

Sounds like the engine had a hiccup.

iirc its the speed sensor or something in the hub, every winter when I DD'd my silver car it would do that when I would hit a huge bump

I think its pretty common because I see threads about it all the time on rgs.org

Maybe james knows the correct fix?

So I shouldn't worry about my car breaking down after I drive 150 miles tomorrow?

Eet gunna esplode


wheel sensor its common
You get a tiny bit of where in the bearing and the clearance between the sensing element and the tone ring gets larger and then you get s***** signal drop out at low rpm's
the galvanic corrosion between the aluminum knuckle in the iron hub doesn't help things either
you're finding Dr minutes at least for more than a hundred fifty miles because the wheel bearings while having a pair of play are not bad if they were bad that would be on all the time
you'll probably put another 20k or more miles on it....it will get worse or you can pull ABS fuse and not worry about it and learn how to drive like a real man without a computer helping you...

as you can tell my voice to text has not figured out that I'm a gearhead

My wife's '02 Buick would do that when the wheel bearings were going out, the ABS sensor is built in. In 160k miles we went through 4 wheel bearings. On this car, it would also disable the AWD.

Thanks for the replies
Both front wheel bearings were replaced about 50,000 miles ago and the backs have 100k on them. I put the car on jackstands and did a visual check. I also shook the wheels to see if there was any play. I didn't feel any. I did notice a humming sound while driving though.

A bad crank sensor can cause this issue too. If it's the crank sensor, the tachometer tends to drop to zero while the motor is still running(may only be for a second)..... Wheel speed sensor is more common though.

 

[Turbocharged400sbc]

humming sound is probably feathered tires so you should probably cross rotate em
the wheel speed sensor will still drop out even if you can't feel the play it does....that's because you can't exert 8000 +pounds of force on it
also keep in mind that the sensor is on the inside of the wheel bearing towards the rear of the car so when you hit the brakes the weight of the car shifts forward and the play in the bearing moves the tone ring away from the sensor and BAM! signal drop out.....
Ask tg how many bearings he's replaced on his aztek....and I'm pretty sure he just borrowed my scanner because it happened again after only a couple of months with new bearings

very likely wheel speed. My white car did this for a year or two, then I took the car for a blast the other day and it went out completely. Now it all just stays on.

You can do awesome burnouts once all that stuff stops working btw.
