Good afternoon, I hope someone can help me with my HHR. The Check on the dashboard turned on and, since then, I've started noticing an accelerating deficiency. The failure has worsen with time and now it won't even advance along an uphill road. I've scanned it and the code that is indicated is P0016, which means a camshaft's misalignment. I would appreciate anyone's help.

The power steering suddenly generates error codes and, for its own safety, it is disabled and thus the manual steering is left without asistence. This makes the turning or maneuvering the car really hard.
