sensors are likely out of adjustment.
a new set of plastic caps from the dealer ($5(or so)/set) will help the
adjustment.  with new caps, you push the sensor in until you hear the
teeth scraping plastic while the wheel turns, then tighten the clamping
bolt.  worst case is damaged teeth on the cvj or sensor is bad.  you can
check this by looking at the sensor signal output with an oscilloscope.
