I just bought a 2001 ranger and the abs light was on, looked at the abs sensor in the front and seen it was not hookd up, so i hooked it back up and it went off but as soon as i started to move the truck the light came back on, i already replaced the front right and back sensor, any idea on wat it could be? thx in advance

Too many possibilities. You need to have a scanner that does abs systems used on it and see what the codes are. This could be anything from a faulty wheel speed sensor to a bad abs module.

00285 - ABS Wheel Speed Sensor Front Right (G45)

Remove the front right wheel, confirm that the tone wheel is intact and not all flaked with rust. If it looks good, scrape out the gaps and get a new wheel speed sensor.

broken wire on harness? I have had troubles in the past with this kinds issue. remove wheel, brake caliper, rotor and you should have access to the sensor. most time they are connected with a allen bolt. remove abs sensor and you will find a fuzzy metal like stuff on it. Like draging a magnet on the dirt, sometimes just cleaning it off will do the trick. the fuzz interferes with signal and set off the code. Here is were its your choice ether clean it off and reinstall or replace with new sensor.

Take it back to the garage and make them pay for it. If it was damaged while they were replacing the bearing, it's their fault.

After a while the light will go off. but autozone should have cleared it for you. If you bought the part through them.

i think it does, an easy way to know is to turn the ignition on and look for the abs symbol, it will light up in yellow and say abs, or look at the back of the front wheel and see if theres a sensor, hope this helps.

The ABS light indicates there is an issue with your ABS. If there is an Auto Zone around your area, have then scan the ECM for the DTC codes that has triggered the ABS light to come on. The common cause for this in your truck is a bad or dirty ABS sensor at the front wheels. Buy a can of brake parts cleaner and a brass feller gauge or you can just use the paper trick. Locate the ABS sensor on the inside of the front wheel hub and spray it clean with the brake parts cleaner and look for any damages caused buy corrosion or broken wire leads to the ABS sensor. If all wire leads are good, check to make sure the gap from the ABS sensor to the speed ring on the hub is correct. The gap should be 0.005 to 0.050 inch (0.127mm to 1.270mm), use a brass feeler gauge so it wont stick to the magnetic abs sensor or the thickness or a paper folded in fours. Good luck and hope this helps.

trac control & abs light staying on in dash on pt cruiser 2001 limited
well had same problem with my pt cruiser 2001, firstly there is no need to plug in computer under the dash for pulling abs error codes,
because the problem can be the cracked abs ring on the drive shaft/cv joint,
turn your steering all the way to left and ask your colleague to see if behind the tyre the abs ring is broken or cracked,
it is circular like a bracelete with grooves, then turn the steering to the right and repeat the inpesction,
if the abs ring is cracked then look on ebay or web for pt cruiser abs ring or kia abs ring, should cost about £5-£10 each
and a garage could heat it up with gas and hammer it into the drive shaft/cv joint for you for about £20-£30,
takes about 30min to 45mins, make sure the garage dont heat the cv booth kit rubber next to the abs ring when heating it up.
i heard you can only buy abs ring for front wheels and its not available separately for rear wheels,
so for rear you may need to buy the whole part it comes on
the front abs rings are easily visible when you turn the wheel to one side, the rear ones may not be visible as i have not seen them
so if the abs ring are good then it wil probably be one of the wheel sensors, in this case you you may look for a garage who will hook up
the computer and pull the code for you, be carefull if the say there are no abs error codes it means the sensors are ok and most of it
there is no need to buy abs sensor for any wheel when there are no error codes
on pt cruiser you can pull engine error codes yourself without a computer, just do the key dance on the ignition,
turn key until dash lights come on then switch off and then again turn key until dash lights come on then swithch off,
then turn key for third time again until dash lights come on , you will see engine error codes displayed then says done,
if there are no error codes it will say done, howevere these are engine error codes only not abs error codes,
abs error codes are pulled using abs diagnostic tool
incase its a faulty wheel sensor, will cost £45 at dealer or £20 from scrap, then a garage can removed the tyre and plug out the old sensor cable
and replace it with a new one, one end is easy to plug in but the other end has to be pushed in at an angle,
its about 30min job and garage can charge £20 or so
my pt cruiser is back on the road with just one abs ring replaced and it all cost me £30 alltogether

When you start to loose your abs sensors(more than one)the brake light will come on.with one sensor going the abs light will come on.I would have your front wheel bearings check seen as how that is were the sensors are.If a weeering sound happens while driving and increases and decreases with with speed I would definatly suspect wheel bearings.

Anti-Lock Break System is activated.it could be somthing as simple as a sensor out of adjustment or rust build up or a tooth missing on the exciter rings, now and then i have seen a broken wire right off the sensor. without actually looking at your car with either a scanner or at least a meter or your wheel sensors it can be hard to say any more. increase your following distance and make an appointment to get your car looked at.
