Hillbilly,
If the sensor is working as the drive shaft is turning your meter should indicate an AC voltage and I am going to have to guess because I don't have a specification for that vehicle that it will be between 1-5 volts AC at low speed and go up as the speed increases. It would probably be wise to try to find the exact spec if the sensor is sending out a voltage signal at all. I don't think you will see any voltage signal because I think that the sensor is your problem. If you do get a voltage signal though this could indicate a wiring problem or as I said before a bad sensor buffer module or PCM. The sensor send out an AC voltage signal and the buffer converts it into a digital signal DC voltage that the PCM cruise and other components that need a speed sensor reference can use. I think the sensor or wiring connection is probably the fault because in general we just don't see module and PCM failures like we used to these components are usually pretty well protected and the quality has improved greatly. If the sensor is faulty I would recommend using a good brand name replacement Nissan, Napa , Carquest component the cheap stuff from Advance and Autozone just don't see to last for the small amount in savings. Good Luck,hope you find this useful. - Starbuck
