1997 4 runner Limited P0335 Issue

I have a P0335 code for crankshaft position sensor. The crankshaft sensor is good ohm 2000, the teeth are fine on my crankshaft, wireing rings out good, signal .5 volts at ECU. The weird thing is that if I move the sensor or ground to something it kicks fuel and ignition on. It seats good up next to the crankshaft teeth but will not read on my tach or signal. Grounding is good, by the way. Any thoughts?

 

I'd try replacing the sensor. Maybe it's weak? I know they are just a hall effect sensor so how they can go weak is beyond me, but it looks like you've narrowed it down to that part.

 

New sensor is installed. I have bought 3. 1 used OEM, 1non-OEM and the newest is new OEM. Non have changed my issue.
