Help testing E70 X5 N55 crank sensor !!!

[Beemernoob92]

I need help testing the crank sensor on a 2011 BMW X5 N55. I'm getting a crank no start and code for crank sensor implausible (I will get code tomorrow and update this) so far I have replaced the sensor with 2 other used ones that I had know good sensors. I have tested continuity from the crankshaft sensor to ECU connector and it is good. I have checked 3 wires on the crank sensor connectors I have a yellow wire which has 4.81V on it a black and green wire which is ground and a blue and yellow which has 4.99V on it. I tested these wires at sensor connector unplugged and back probed the ECU side also. My question is would anyone know what the voltages should be and what the best test to do to confirm that the sensor is working ? Thanks
