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.

hi if you know for sure it's a wheel speed sensor
remove that wheel
remove the caliper and caliper bracket
remove the brake rotor
there are 3 bolts on the other side of the knuckle(13mm)
remove them
remove the axle nut(1 5/16)
remove the hub bearing assembly(you may need to use a hammer on the hub flange)
hope this helps

SOURCE: 1995 Buick Riviera SC: traction and the security light

traction switch is located next to drivers left knee on bottom of dash....you should be able to turn off the traction light there by just turning on the traction control.....the security light is telling you that there is a problem with your security system....could just need a new key with a new computer chip....make sure the key is clean and dry when using so it can read the chip....the security light comes on whenever your start the car and stays on for approximatley 2 minutes and then should go out....it is just a reminder....try this and see if it works....lock the door using the power switch on door.....close door and see if the security light comes on....watch and it should go out after about 2 minutes...if it does then your alarm is activated and working....to disarm you need to unlock the driver door with the key...anything else will set the alarm off and the lights will start flashing and the horn honking...after you set the alarm off you will always have to use the key to unlock the drivers door to turn off the alarm and reset the security system.

There is a good chance that the wheel speed sensor, (ABS sensor) has gone bad or gotten to dirty. It's common for the ABS sensor to get too dirty and can not read the speed ring on the wheel hub since it's magnetic. The common repair is to spray Brake Parts Cleaner on the ABS and speed ring on the hub and inspect for damages to the wire harness. The ABS sensor is on the inside of the wheel hub so it's easy to get to, if you not sure what your looking for. Remove the wheel and along the A-arm, you will find a wire harness which leads to the wheel hub (Bearing). There is where your going to find the sensor, just clean it and inspect for corrosion and gap, you can take paper and fold it 5 times and place it between the sensor and speed ring for the proper gap. Good luck and keep me posted, if there is a Auto Zone around your area, have them scan the car just to make sure it's not your ABS modulator which would cast $$$ to replace.

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.

My 2002 Lincoln LS v6 Lost Engine Power,Traction Control Light was flashing & ABS light Came on! ANY IDEA?


Had the same problem with my 2002 Lincoln LS, it was a bad wheel speed sensor. The right front wheel bearing had some play in it, so I had the hub assembly replaced. The hub assembly comes with a new wheel speed sensor attached. After I replaced the hub assmbly with sensor, the ABS and Traction Control lights went off. No problem since!

Abs sensor


The ABS sensors are located in the bearing wheel hub assembly, "normally" these sensor's cannot be removed on most models but it may be possible on yours....This will require removing the tire, brake caliper and possibly the bearing hub....One thing you can do is carefully inspect the wiring going down to your wheel bearings, if you find damaged or frayed wiring or your connections look bad, you will end up most likely replacing the hub assembly. These are normally about 75-100 dollars each and they are not hard to replace yourself if you are somewhat handy with a wrench. A dealer can tell you which sensor is giving you the trouble, or maybe Pep Boys or some auto parts stores may be able to help in this way too. Most times this ABS light you have on is also associated with the "Trac Off" light on all the time too.

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.

I own the 2002 Buick Rendezvous CX and I've encountered the same problems listed here. The ABS / Traction Control Lamp stays on and was throwing a code for the left wheel speed sensor as well as an anti-lock brake code (both in the wheel bearing hub assembly). I replaced the left and right front wheel hub assembly yet this did not eliminate the abs codes. 
Ultimately, I traced this problem to a break in the wire that leads to the left hub assembly. Although the sensor was properly connected, the wire (which is encased in a plastic housing) was broken. This is the wiring which leads from the abs wiring harness under the hood down to the left wheel abs sensor. 
I would suggest that you simply remove the left wheel and inspect the wire that leads to the abs sensor (there is only one wire on each wheel). Mine literally fell apart when I removed the plastic housing around the wire. I spliced the wire together and put it back in the plastic housing. After this, my abs codes disappeared and my anti-lock brakes began working again!
This is a simple fix that many people spend $1000 + on by replacing the hub assembly which does not fix the problem.
