I looked around for ABS issues but did not find anything to my question .. Mine started last summer running along interstate light just popped one I had just run over some paper and stuff tossed out by a diver food bags and stuff so I figured maybe some trash go into the area under wheel sensor I stopped a bit later for fuel and lite did nit come back on at start up.. Did not come on again for several weeks I scanned the system said faulty sensor circuit .
My son in Law has a mech. at his dealership to look it over he plopped a new sensor in it .. Light came back on again a day or so later I think there is a bad connection at some point .. I took the one at the wheel and the one right at the fender well liner a my scanner said it was right or passenger side front both times I scanned it .


My question is anyone know how many more connections there is its almost impossible for my crippled up *** to crawl and climb all over and under the thing to clean the connectors and add some dielectric grease and or has anyone else had the issue . Thanks for any help or info

 

Same issue with my '06 4WD F-350. A scan detected a faulty L\F sensor. The ABS light will intermittently come on then after a while go out by itself. I haven't taken it apart yet but I'm interested what you find. Please post your findings.

I'll tag along.....same issue - 2006 F350 5.4l 4wd. I use it mainly as a plow truck. ABS light would come on, then go out. Figured it was ice somehow messing with the system. Happens in the summer tho too. Goes on and off with no apparent issues. Only drive it about once a week during the summer to keep the critters from building nests. Figure it's just a sensor somewhere.

 

The tone ring and sensors do need to be cleaned periodically. Try that before replacing anything.
