Hi J Patrick,
It is likely either that or the space between the sensor and wheel is off. Very anecdotally- When it is hot, and left out in the sun, the ABS light goes off. A couple times when I jiggled the connector to the wheel sensor it went off.
As you might guess- this isn't real high on my list of crises to deal with . BI will someday, but the weather was really nice today so I drove instead of worked on it.
