Well, looks like a bad/weak sensor ...
I hate to do a diagnosis w/o using the proper equipment , but in your case it would be a pretty fair and logical determination.
There are many articles that claim the sensors can loose the flux propertires by getting jarred or even by the front end parts getting rapped with a hammer when doing repair work on tie rods/etc...so, no shorts, no bad connection, reluctors check, ohms spec , etc could equate to a weak sensor.
Just b/c a sensor ohms out spec does not mean it generates the proper/ required signal... [ that's where we go back to a scope..we are not interested in the coils ohmic value, we are interested in the sine wave the sensor/reluctor generates...an ohm value just says it is supposed to put out a signal..I want to SEE that signal when I diagnose.]
You are seeing the V output [ or rather , the weak V output], so bad/weak sensor possible looks better than anything else at this point.
