ABS SNAFU help
I had blowout on my left front, thanks to the Lord I made it to the shoulder. After I cleaned my pants, changed it, and got home, I had the ABS light on. I noticed the cable for the ABS sensor was severed, by the flying tread I imagine. The connector was gone and all that was left was the hanging wires. I tried splicing them together (both ways) but the ABS light remains. Any ideas? Is there a specific resistance it looks for, or do I need to drive it a little bit to send a signal or what? After the first 8 months of this year I'm about ready to drive my truck downtown and leave it running with the keys in it! It never ends.

I recently replaced my front wheel bearing assemblies and they came with new ABS sensors. If they will work and I can remove them, you can have it
I remember after the ABS was unplugged, the light stayed on for a bit. I can't remember if clearing the DTCs fixed, key cycle, or what

You have proven that the wiring was damaged when the tire broke it. Buy a new pigtail/sensor like the ones at this website:

I would take ExPaCamper up on the offer. I save my old sensors just in case something like this happens. I may have one left.
Like Larry stated, the wiring was damaged. I do not know how sensitive to differences in electrical resistance the Hall Effect (HE) sensors and ABS/PCM modules in our trucks are, but I do know that you cannot just splice the wires together on some robotic applications (resistance has to match with all interrelated sensors) and you've more than likely added resistance with your slices.

I had a similar issue where the ABS electric line from the hub made it but the wire on the computer side broke and there was not enough meat on the engine side clip after patrolling the junkyard for fords in general to find the part I did. A key part of the procedure is using the soderfilled connectors this ensures a waterproof connection and minimal added resistance. After installation the ABS light remained on until exiting the driveway. 20,000 miles later its working well.

My thread with ABS light ON after replacement/unplugging and plugging back in.

I've been out of pocket for a few days, but thought I'd post an update: I couldn't get the idea out of my head that since the abs sensors should only be sending a discrete signal to the abs module, i.e. going high as each tooth passes and low when it's not, resistance shouldn't matter, only the presence of a signal or not. Anyway, I spliced the wires again and just like RigCity, the ABS light cleared soon after I left the driveway. Thanks to everyone, especially ExPaCamper for the offers of help and parts!
