Problem with 2008 gear tooth sensor

My problem is that the "S" output is steady at about 4v DC with the output pulses riding on top of this DC voltage. The pulses are much wider than last year's sensor. The pulses are about .5v p-p and are 10 mS wide. Reversing the gear direction reverses the duty cycle so the pules are about 25 mS.

I was expecting the output to swing from 0 to about +5v with the narrow uS pulses as with last year's sensor.

I checked the +5, Gnd and +12 connections and voltages.

My question: has anyone had problems with this year's gear tooth sensor?

Thanks, Larry
