I'm going to ohm my speed sensor tonight and replace if need be.
Thanks guys.

 

The Black/orange wire is in the kickpanel. remove the plastic and it will be taped there with other wires. Disconnect it and ground the black/orange wire with the ignition in run. The abs light will flash a series of codes. For ex code 4 will be 3 short flashs followed by 1 long one.

I replaced my vehicle speed sensor on the rear differential last night.
I shopped around, and the least expensive was the motorcraft product
at the Ford dealer parts counter, $22 with tax. Napa was $27 with tax.
Autozone wanted $47.73 with tax, more than twice the price for after market!
Unplugged the negative battery terminal while I did the work. Swapped it
out, let it run for 15 minutes, took it out for a drive. Light is gone, runs alot
better. The old one shows an open circuit. Thanks again guys.

 

Hi! Could you please describe where your speed sensor on rear differential was located?

 

Disconnecting the battery has no effect on the ABS computer.

It only turns the light off when the self-test passes and there are no further self-test failures.

Makes sense when it's put that way. Thanks.

 

the speed sensor is located in the rear differential case. It will be the only item with a wire going to it on your diff case. Make sure you clean around it before removing it so you dont get any dirt into your fluid.

Thanks. I replaced the sensor located on the rear differential case and now the ABS light is gone.
