The P0340 code is for the intake camshaft position sensor (G40), not the exhaust camshaft sensor. I would swap out the camshaft position actuator and make sure the engine oil is full. I would recheck all of the engine wiring harness grounds, one might be off or loose. Here is the location of the camshaft adjuster solenoids. Let me know

Okay, sounds good, I would check to make sure the electrical connector is in good shape as well.
