Take it back to whomever did the repair and have them fix for free. I suspect the new sensors are wrong, installed wrong, or something else. These sensors tell the brake and traction control computers what to do.

03 Bonneville brake light and antilock and traction control lights stay on

You need a code reader with the ability to reset ABS systems to make the antilock light go out. The brake light may be due to an improper bleeding procedure.

Service engine, antilock brake, and trac off sensors are lit in 98 Olds Intrigue

Yes it is possible that you have a bad wheel bearing which has the abs sensor in it. Hence the abs light on. Traction control utilizes the abs as inputs therefore traction control will come on.

My trac light is on, on the dash board. Where is the wheel sensor located ?

Your vehicle is equipped with 4 of them. They are located at each of the 4 wheels. There are other reasons that the Traction Control light can come on...wheel speeds sensors are not the only reason, athough they are the most common. The traction control system works with the engine/powertrain control system and with the antilock brake system. A bad wheel speed sensor will usually also turn on the Antilock Brake (ABS) light. If the Check Engine light is also on, you could have an engine control problem causing the Trac light to come on.
If the Trac light is on by itself, you may just have the traction control turned off. The Trac Off switch is located on the steering column.

If none of the above solves your problem, then you will have to scan your computer system to find out why the light is on. ( i.e. failed wheel speed sensor...but which one?)

The antilock brake light on the dashboard will not go off.

If this car is older it is most likely a wheel sensor. GM put abs sensors on all four wheels built into the wheel bearings. If one of these sensors goes bad, your abs light, as well as traction control ( if equipped) will shut off and show low traction. Unfortunately, to figure out which one is bad, you need to have your car put on a chassis computer

Antilock & traction lights stay on what is the problem? Brake fluid is full, brakes seem to work fine.

Make sure your tires are all the same size[did you just put on only two new tires?] . Then check the wheel sensors.Also make sure your tire pressure is perfect!

What sensor lights will come on when a wheel bearing goes bad in a 2001 buick century custom

Hello mobrien.
Depending on what your car is equipped with. Antilock brake systems work in conjunction with traction control.So if the antilock system has a fault, traction control will also default system off. It may also turn on low pressure in a tire if your car has that feature.
In the bearing/hub assembly on your Buick there is a sensor ring that rotates with the axle. A sensor is positioned close to that ring to read wheel speed.
A failed bearing doesn't necessarily damage the sensor, nor will a bad sensor mean the bearing is bad. But on your vehicle if one fails the assembly must be replaced as a unit.
I hope this answers your question.If you have another leave it in a comment and I will answer you.

Antilock light is on and trac light is on sound

You have a bad hub bearing. 100% garunteed. The light is on because the bearing is so bad it hit the sensor for the abs & traction control , breaking it. So you're gonna need a bearing, a sensor,probably new brake pads,any seals{probably one} & a shop that can do it. The bearing is pressed in & needs to be pressed out. Heating & beating is not a good idea.

Antilock brake /trac off light stays on...140000 miles

In those cars, the wheel speed sensor is integrated into the wheel bearings. When one of the sensors goes bad, you have to replace the entire wheel bearing. Also, when the sensor(s) go bad, it will cause the loss of anti-lock braking and disable the traction control system.

The only way to identify which wheel bearing it is, is to hook the car up to a scan tool capable of reading ABS codes. That said, the front ones are more notorious for going out than the rear ones.

My 1998 Buick LeSabre has two indicator lights that are on

it is a warning that the computer has detected an error in the anti-lock braking system. it could be caused a number of different reasons, you could be low on brake fluid, or you could need new front or rear brake pads or need adjusted, there could be a loss of pressure in the system and the lines may need bled
