By "were done" I am guessing someone else did the job for you. It is a common error at garages to forget to reconnect the sensors so that is my first thought but then you say you changed the front sensors, was that after the brake job and do you have 4 wheel ABS? The plugs for the sensors should always be cleaned if not replaced after a brake job in my opinion (high dirt area). More info will get you a better answer if you post back I may be able to help more/better.

SOURCE: '98 Windstar ABS and traction control lights after getting brakes done

Prior to the brakes being replaced you more than likely had metal to metal contact which can throw metal shavings on the ABS wheel sensors. This metal shavings stick to the road grime on the wheel sensors showing the ABS computer a false reading making the ABS light come on. On Ford Windstars, the ABS light and the traction control light are on the same circuit. A simple (and cheap) fix is to pull the ABS wheel sensors and clean them with brake cleaner or throttle body cleaner. Make sure you dry them well and reinstall. On the Windstar there is one bold holding the sensors to the back of the wheels. I recommend you spray some WD40 on the bold and wait about 10 minutes before removing.
If this doesn't fix the ABS light and brakes, you can have the ABS system diagnosed at a shop for about an hour labor. (Usally about $100)
I have fixed many of these type of problems just by cleaning the ABS wheel sensors. Good luck.

SOURCE: after replacing the left front wheel bearing on a 2003 ford focus, the abs and traction warning light stay on

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

The first thing i would do is check the wiring on all four wheels.It could be a faulty solenoid.The next thing is a diagnostic check.

What does it mean when my anti-lock brake light comes on and the low traction light comes on and shuts off?


You need to have the ABS system scanned. You probably have a bad wheel speed sensor. most likely located in one of the hub bearings meaning; you may have to replace a hub wheel bearing assy with the faulty sensor. Traction control uses the same speed sensors as ABS. when the warning lights are on the system is not working.

Why does the "service traction system" and "service ABS" light to come on when driving?


The service ABS light on while driving means that the ABS wheel speed sensor is defective or a broken wire that goes to the sensor. You now only have regular braking. This means that you can now lock up one or more wheels with hard braking. Then the car can swerve either left or right while braking hard. The traction control must also rely on the ABS wheel speed sensor to keep both front wheels spinning at the same speed for safety reasons. This prevents loss of control of your car while getting better traction with the tires.

My services traction light comes on on my 05 chevy impala and my abs light doesnt go off neither does my trac light. What could be the problem? and how much would u think i looking at in cost to fix it?


Very common problem. The MOST LIKELY cause is that you have a front wheel speed sensor that is not working properly. This could be due to a bad front wheel bearing assembly or it could be a wiring problem. GM has had a LOT of problems with the wiring harnesses. A company named "DORMAN" makes a harness repair kit. (See picture below) The Dorman part number is: Part Number: 970-041 The wheel speed sensor itself and the wheel bearing come as a complete "HUB" assembly. The wheel bearing should be checked for looseness and the speed sensor should be tested at the speed sensor connector for AC voltage output when the wheel is spinning. If the bearing or the sensor is bad, then you must replace the hub assembly. If this is the case, I recommend using the "Timken" hub assemblies. They are more expensive, but are much better quality. I have had many problems using the cheaper brands. (See picture below) If the wheel bearing and sensor is OK, then the harness should be replaced. You will have to scan your Antilock Brake System (ABS) module to find out which one is causing the light to come on. As far as cost...it depends on exacltly WHAT it needs and WHO is doing the job. There also may be more than one speed sensor giving you problems. Your best bet is to get it diagnosed and get an estimate of repairs. If they try to sell you a hub assembly, ASK them if they actually TESTED the speed sensor. MOST mechanics out there will just throw a speed sensor (hub assembly) at the problem if they have a speed sensor code, only to find out later that the problem is in the harness. Of course, the customer is the one who ends up paying for their incompetence when this happens. dttech_36.jpg

I have a 2003 LS Sport Impala I have relpaced the front wheel bearings twice and have lost the humming noise but still have an issue with the ABS and traction control warning lights being on. I had it...


WHEN YOU PRESS THE BRAKE PEDAL DOES THE PEDAL SEEM TO JUMP? IF SO THE MODULE HAS SEEN A WHEEL SPEED SENSOR MPH DROP SIGNALING A BRAKE LOCK UP . OR LOSS OF WHEEL SPEED , IF THATS THE CASE THE MOST COMMON PROBLEM IS A BROKEN WIRE IN THE VEHICLE HARNESS NEAR THE WHEEL SPEED SENSOR CONNECTOR USUALLY WHERE THE HARNESS MAKES A U TURN UPWARDS .

IS THE ABS LIGHT ON ALL THE TIME ORDOES IT RESET WITH A KEY CYCLE?

FIRST OF ALL THE TRACTION CONTROLL AND THE ABS SYSTEM ARE BASICALLY THE SAME SYSTEM.

THERE SHOULD BE SERVICE CODES FOR THE MALFUNCTIONS , FIRST THING IS TO RETRIEVE ALL ABS CODES THEN MONITOR WHEEL SPEED SENSOR INPUTS WHILE DRIVING

HOPE THIS HELPS

Traction control and anti-locks(ABS) lights come on.


Traction control and anti-locks(ABS) lights come on there is sensors that are pluged in behind the rotors check and see if they are disconected or loose sometimes when you change your brake pads they might come loose and not making contact.

Brake sensor? something else?


You have a faulty wheel speed sensor. This is a magnetic pick up sensor on your wheel bearing hub and it controls your abs. If the car can not sense all 4 wheels then the abs will default back to normal brakes and your traction control will not work. Look at your wheel bearing hubs and check for these sensors. They are on the underside of the car and are black plastic with a wire comming out of it. A piece of gravel may have broken the pick up or the wires to a sensor may be broken as well. To replace it is usually a couple of screws on the hub assembly and a plug to disconnect from your wire harness.

Traction light stays on as well as my abs would come on and stays on and clicking noise during braking.


Sounds like you have a problem in the front brakes or a front wheel speed sensor. A common cause for a Traction light is a faulty front ABS wheel speed sensor or harness. When the Anti lock brake computer sees a problem in the ABS syetm, it disables traction control as well.

2001 impala abs brakes light comes on only when you go thru water


The traction control system uses the abs wheel sensors to detect wheel speed if the abs light is on the entire abs system will disable giving you regular braking but it will also stop feeding info to the traction control

Abs light


A common cause for an ABS light is a broken wire to one of the front wheel speed sensor, or the sensor itself is bad. The sensor is part of the hub/wheel bearing assembly. A problem in the ABS causes the traction control system to be dissabled, thus turning on that light.
