I just changed both front abs sensors on my 2001 F-250. It took about 5 mins. or less for each side. Couldn't have been a simpler replacement and I could see nothing that you would have to know or look out for on this job. By the way the abs light didn't clear after the replacement until after I drove the truck but it cleared within a few seconds after I pulled out and has been okay since.

well my light is still on. tried clearing it with a good snap on scanner. i also disconnected the left side just to make sure they were'nt switched somehow. the light comes on without moving the truck so i dont think its the ring gear & the magnet looked pretty clean on the sensor i removed. i looked over the wiring nothing looks burnt or cracked....any thoughts? how about the control module? any way of testing it?

heres the code i get C1445 "speed sensor input failure"

ABS fault codes need to be cleared by a dealer, so I am told.

If your scanner can read the ABS module codes, it should be able to clear them.

I've heard that if you put a DVOM on AC volts, put the probes on the sensor wires and spin the wheel the sensor should make a small amount of AC voltage. I think it should increase with the wheel speed.

If your sensor is OK and you are still getting the code, the problem has to be in the wiring.
