Re: ABS Sensor

Jeffrey,

    I was wondering did you replace all 4 tires or just the front or rear
tires?  If you just replaced the two wheels it might be the difference in tire
radius is your problem. I recall a post on the list a while back that suggested
the difference in tire size would cause problems with the ABS system. As far as
the sensors go.  An open in the wiring on one of the sensors, or a "misgapped"
wheel sensor could also produce the phenomenon you are describing.  Of course
that would also suggest "sabotage" by your tire dealer.  I would be more
inclined to think that your problem is your new tires.
