okay i will put a ohm meter to the wires and see if it has power but if the sensor does have power then that means im having problems with the timing chain? like i jumped time or something? and thank you so much for your help

I had the exact same problem,.I.replaced crankshaft position sensor, still had service engine light, I did further research and found out it was the Electronic Control Module, replaced and it runs like a scalded dog.!!! No more codes or service engine light.
