Default P0340 Code still persists!!

Hey all. So in my last couple posts I’ve been messing with a P0340 code for the Camshaft sensor A or something of the other. I was recommended to have a O-Scope done to see if the wavelengths and frequencies were right on the cam and crank sensors. The CEL is still on and still pulling the same code with both cam sensors replaced as well as crank sensor. Im beginning to think I may have an ECU issue, but that sounds a little extreme. I haven’t had the chance to get the O-Scope done to the car, I live in a small town, I’d have to hunt someone to do that. But the car runs too good to have bad sensors in my opinion, it starts every time, no issues.

thanks in advance to all the help!!! It’s greatly appreciated!!
