KIrk yes they do produce an AC sine wave however the actual voltage can vary dependent on many factors, frequency and amplitude increase with engine speed.I've found that most (not all) have a hard time with the AC voltage test so a quick resistance test of the sensor or the jumper wire test usually indicates which way to procede. Thanks for sharing the info. Joe
