Engine camshaft position sensors, code P0345?

I'm getting code P0345 Camshaft position sensor circuit malfunction (bank 2).
I'm also getting code P0349 (CMP)Sensor A intermittent (bank 2).
From the research I've done, bank 2 is on the drivers side at the back of the engine by the firewall.
If this is all correct, then the main question is, Is sensor A the intake or exhaust sensor?
Thank you!

Here are the locations for the sensors but I can tell you that if the engine oil is low or dirty you will get these codes because the camshaft actuators will not work correctly. Also, a bad camshaft actuator will cause these codes as well. They were not nice when they put the sensors at the rear of the engine. If the engine is making noise, you could need the ford classic timing chains, guides and actuators, this is very common.
