Wheel speed sensor trouble

[87TTops]

I got the Trac off/ABS light combo, so I checked the ohms of all 4 speed sensors. I got varying readings on three of them, all around 1.1k, but the passenger rear gave a reading that started at about 20M, and increased until it hit infinity in about 5 seconds. I did it multiple times to make sure. My guess is that this is the bad apple, but I wanted to make sure before I bought the hub that I wasn't just testing it wrong or something else I did, because it was very hard to get the leads in there with the wheel on from under the car, since I didn't feel like taking em off. Also, I want to make sure this is the only bad one, because I noticed some other posters replaced a hub for not having 1.09k, which only one sensor had exactly.

I'd also like to note that before I got the lights, when leaving a parking lot (car just turned on, leaving from a stop with the wheel turned) the traction control would kick on for no reason until i straightened the wheel. It would go away quickly but it certainly shouldn't have been doing that, so I knew something was gonna break soon. The trac off/abs combo was intermittent for the first couple days too, but now is permanent. Hope that helps.
