Hi,

Had a continuous ABS warning light on, previous owner told me it was the front right sensor, which I have just replaced... now when I start the car, the ABS light comes on briefly, then goes out as I would expect (seems to pass the self-test).

When I start driving however, it comes on after about 20ft or so and stays on, until the next time I start the car.

Has anyone had a similar problem?

I know I really need to get the ABS codes but don't have access to an ABS scanner - does anyone know which pins on the OBD2 port to jumper to get the ABS light to blink the fault codes? I can't find that info anywhere!

Many thanks!

 

Sounds like the sensor is too far or too close and its putting on the ABS light.

 

hmm, it's bolted in with a single bolt... wonder if it's pushed down firmly enough into the hub, thought it was sitting down ok but worth double checking!

 

There could be metal debris on the ring from the brake rotors... Also check the wires they could be coming in contact with the rinsed not done right. I have had this happen to my blazer personally.... I hope this helps...

 

With the rims... Sorry for the typo...

 

Will look at it again one night soon, thanks for the help... I wondered if the sensor was sitting up very slightly when I fitted it (only talking about 1mm!).

My plan of attack is to remove the sensor again, and rotate the hub, looking through the sensor hole to see if the teeth on the hub are all in good condition and free from dirt. I will then re-seat the sensor, maybe giving it a light tap or two with the handle of a screwdriver to ensure it is sitting completely flush with the hub.

I'll keep my fingers crossed that it fixes it, otherwise I think it'll be a trip to the local garage and £50 diagnostics

 

im having this exact problem with my 2000 i replaced the passenger side and now it only goes on when i start driving. i heard you can jump pins A and H but i cant identify which pin is which did you solve it?

 

Check the large fuse in the distribution box under the hood, I think it is a 60. I have mine out right now because of the vss in the right wheel being bad. Have not had the time to fix it yet. By pulling this fuse, the ABS is disabled. My light does the exact same thing as you describe.
