I have one thought and it's probably not a good one. There are different width washers for mounting the sensors to adjust for production variances. It might be that one of yours was set up at the maximal distance from the wheel ring and something got tweaked. It's worth trying a thinner washer and seeing of mounting it closer to the ring works. IIRC the washers come in sets from the dealer, i.e., order a washer and you get a set of three. If nothing else, look up the tolerances and measure yours. ABS sensors are pretty dumb devices; it's hard to imagine how one could go bad other than a broken wire.
