Default ABS problem

Hi, my name is Dan. This is my first post. I own a 2001 Ford ranger with the step side. I'm having issues with my ABS. When I come to a slow stop the ABS kicks in. I feel like the sensors are probaly reading the speed wrong. It does not happen all the time, but when it does, it's only at slow stops. No codes show up. Has anyone experienced this problem? I'm driving without the ABS right now.

that happend to me a while back. the wheel speed sensor is probably the cause.
when you slow down the sensor thinks a tire has locked up (but it hasn't) so the sensor is sending the signal to release the brakes. cost me around $ 600 to replace both sensors
the sensors are like $200 a piece.

Thanks for the quick response. Where are the sensors located? Can they be removed and tested and cleaned?

with mine they were in the wheel bearing. you can remove the sensors from the wheel bearing. i dont know if ford kept them in the same spot and i dont know anything about your truck to really help any further...
you need to create a signature, it tells everybody the year of your truck, engine size, 2wd or 4wd ect....

The speed sensor is mounted in the steering knuckle

I need this info and more so thanks for the posts and keep them coming! I have my engine running great now so of course I have expected all hell to break loose everywhere else what with 125000 miles plus on my '99...and sure enough this past week has seen the abs light come on and stay on and sluggish shifting. I guess I need to pull the rear end cover and see if something is amiss. My cousin garage mechanic claims the abs sensor is in the rear punkin but it may be somewhere else as some of you have experienced. Any suggestions in addition will be much appreciated. I'm also having trouble shifting so I expect the slave cylinder in the tranny is not working properly.

There should be 1 in each knuckle and there can be 1 mounted on top of the rear end. Theres no reason to pull the diff cover off as it bolts on from the outside. Having someone hook up a scanner to your truck to see which sensor is dropping out is the easiest way to fix it otherwise your gonna end up replacing all of them trying to fix it. They can be called either a abs sensor or wheel speed sensor.

Wilson, 98, 99 amd 2000 rangers have a vss/abs on top of the differential. This sensor feeds the pcm for info. they can cause issues with shifting, an erratic abs light, an erratic speedo, clicking noises from under the dash. the part cost $20 at AZ. it is held in with 1 bolt at the top of the diff, there is a wire going to it. it pops right out it has an oring on it. clean the area off well before installing it has to sit perfectly flat. you should check your difff fluid while you are there mine was down a quart. the filler plug is right even with the drivshaft

I just unplugged the fuse for now. It's better to have regular brakes than a faulty ABS. My front sensors are OK, I removed the sensors and inspected the teeth inside the hub, all intact. Need to check the rear next.

Default ABS is the smallest problem!

My ABS light was on for a few days and the speedometer was intermittantly operating until I could get my Ranger into a trans shop. A week and 2500 dollars later the trans specialist said I had 20 thousandths transmission end play but the specs call for 4 to 6 thousandths. This damaged the fifth gear and several other components. He claims the trans was incorrectly assembled at the factory. Can I nail Ford for this even though I've been driving the truck from new for ten years and 126,000+ miles?
The trans shifts better than new now!

While the truck was in the shop i was using the wife's Honda Accord to run my errands. The first day I got my truck back from the shop the wife came home with the "check engine" light glowing in the Honda. The Auto Zone rep said the code on the computer indicates an electrical transmission problem!

Who has cursed my family?

So far the 2400+ dollar transmission repair bill has been worth the money. The trans continues to shift easily. In fact it works better than new but since it was never assembled correctly in the first place that shouldn't be a surprise.
Come to think of it; around 60,000 miles i had to replace the rear bearings. The local garage man had no clue why they failed. I think I know now. They were installed incorrectly at the factory originally just as the transmission was. I must also now have the rear end rebuilt probably for the same reason. Can i sue Ford Motor for the cost of repairs?
