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.

I have a 02 Cavalier that when your driving the Trac off light comes on when the light is on it runs rough and shifts hard but if i put it in park turn it off and restart it it's fine


There is a malfunction in you antilock brake/traction control system. When the TRAC light is on, the computer is trying to tell you either 1. That the traction control is active and is controlling your brakes, engine and transmission to stop a wheel skid, or 2. There is is a malfunction in your traction control system.

In the first case above, the TRAC light will only be on for a few seconds until the conditions causing your wheels to slip no longer exist. If the light is staying on even though there is no way your wheels are slipping or skidding, then this is a malfunction. You must scan both your Powertrain Control Module (PCM) and your Antilock Brake System (ABS) module to properly diagnose a problem with this system.

My trac light says trac off, and my abs light is on. what does that mean? I have a 1999 grand am Pontiac.


the trac light is the traction control, the abs light means the antilock brake system is not functioning properly. the trac control is no issue. the abs will not cause the brakes to fail but they will lock instead of pulsing.

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?)

Abs and trac active dash lights are on


If they are coming on momentarily when you are driving in slick conditions this is normal operation. If they are staying on all the time, even when you are driving on dry pavement. there is a broblem with your Antilock Brake and Traction Control system. A very common problem is a wheel speed sensor that is malfunctioning. Your vehicle is equipped with 4 wheel speed sensors. You will have to access the data in the Antilock Brake Control Module to find out which one it is.

Parking brake light stays on


If it's just the light that stays on, often that's a sign that your brake fluid is low.

Antilock brake light stays on


Start with checking the sensors on each wheel.  These will be the electrical wires that come from behind each wheel.  Also check that the tire pressure in each tire is the same.  Next, check your brake fluid level.
Sorry...that's all I can help you with.  Maybe someone else can help you from here.
