The codes are indicating an issue with the engine control module (ECM) detecting a variation in the mechanical timing between the crankshaft and banks 1 and 2 camshafts. On the newer vehicles with VVT, the ECM will actually try to increase valve lift during higher engine speeds. The codes you provided, although are specific to the VVT system, are general codes which could be the result of several things such as sludge in the engine, worn timing chain/guides, or a wiring problem. Since you do not have any power signal to the sensors, wiring is where I would start. Trace the wires from the sensors to the ECM. If possible, simply check them for continuity. Chances are there is a break in the wiring or a corroded connection at the ECM.
