ABS Light and codes
 

Have an ABS light. Was on a 300 mile trip cruising down the freeway the ABS comes on.
Codes:
C1145 Right Front speed sensor input circuit fault
C1234 Right Front wheel speed senor input missing
U1900 ABS Comm Bus Fault
B2900 VIN mismatch

ABS light not on when I start the truck, and after driving a short distance I can feel the ABS pulsating in the brake peddle and then I get the light.

Any tips would be appeciated. Pictures are a big Plus.
Thanks in advance,

Update,
Replaced the ABS speed sensor on the front right and all is good. Wish I would of just taken the sensor out and cleaned it first. It was so caked with brake dust that I could see that causing it not to register.

How easy is it to replace? I have the same thing that has been on going for months.

Thanks.

The sensor is just held in with a small bolt. Take it out, clean it and check the wiring, clean the brake dust, clear the codes, and see if they return. If they do then replace the sensor. I believe it's nothing but a magnet anyway.

OK thanks...

Last time I looked I thought I remembered the wire going into the hub and disappearing.

Wasn't sure how far I was going to have to dig into the hub to get to the sensor. Will have to look again and refresh the ol' noggin. That's why I kept putting it off.

Just remember to clean the relucter ring on the hub itself the gaps can fill in with brake dust/road grime. The sensor reads off of those gaps. No gap no true reading.

I watched a you tube video of a guy replacing his. I have a 2WD and it only took about 30 minutes, very easy. I didn't clear the codes or disconnect the battery and when I started back up the ABS light was still on. Stayed on for about 5 minutes and went out and stayed out.
Nice not having that light stare at me. Its easy enough that I'd try to just wipe it down and see if that fixes it.

I just realized you have an F-250 2x2 drive. reread your post.

I have an F-350 4x4 dually.... not the same setup.

That front sensor is buried in the hub.

No end in sight..
