Is it plugged in? It is right under your nose when you open the bonnet.

Check for 5v engine running across the plugs pins 1 and 3, red/black and black.

The fault looks to be electrical but it is the AWA engine which suffers from problems with the mechanical side of the VVT, the ALT is much more reliable. You need to check the signal of the G40 at the ECU.
