2015 Subaru WRX P0335: Crankshaft Position Sensor “A” Circuit NEED HELP

Here's what happened. Originally I had spun a bearing so i ended up rebuilding my engine, and when I put the engine all back together and back in the car I got the p0335 code, found out I put the crank trigger plate on backwards, i took it out and replaced it with a new one. Same code, p0335 even after putting it the right way. I ended up buying a new crank sensor, still no good. Finally, i checked the voltage on the wiring harness... Ground: OK - Power: 12v - Signal: 5v. Am I missing something? Why isn't anything I am trying working? Any suggestions? Really don't feel like taking the engine out a 3rd time haha
