My service engine soon light, anti-lock break light, and my trac off light are on. My car also makes a kind of grinding noise sometimes. I was told that the sensor was set off by spinning tires. It is progressively getting worse and I would just like to know how to fix this problem. Thanks

Your anti lock brake light is part of your traction contol lights so that is most likely a wheel sensor and would be a separate problem from your check engine light.
Do you have an auto parts store near by? They can check these codes for free if so
well for one the traction and antilock lights are the same sensor. If the anitlock brake sensor goes bad and cannot count your wheel rotations then your traction control system will not work either. AS for the service engine soon light that could be part of this system also or it could be totally different you wont know until you get your code read
CHECK ALTERNATOR OUTPUT.MAKE YOUR VOLTAGE OUT PUT IS 13.5 TO 14.5 VOLTS.IF NOT ALTERNATOR BAD IF ALTERNATOR GOOD THE DEALERSHIP HAS TO HOOK CAR TO DIAGNOSTIC TO CHECK THE ENGINE PCM CONTROLS AND ABS BRAKES AND TRAC.SYSTEM.REASON I SAID ALTERNATOR BECAUSE I SEEN ALTERNATOR GO BAD UNTIL IT OUTPUT WAS LOW CAUSING CHECK ENGINE LIGHT AND ABS LIGHT TO COME ON.
You need a new wheel bearing, This also happened to my olds alero, make sure 2 jack up each tire 1 at a time and pull back and forth on them checking for play, once you have found the 1 that has play or wobbles that is the 1 that needs a new wheel bearing
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.
Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.
