Trouble code P0011

I'am working on a 2006 Infiniti G35X with a 3.5 engine. The code came up P0011 which is camshaft posittiontiming over advaned or system performce bank 1. Does anyone have an idea where to start.:banghead:

Do you have high speed clatter? Sounds like the cam phase sensor,bank one. Its located near the firewall on the valve cover. Remove upper and lower plenum, or you can remove the intake/throttle body.15 minutes to an hour,depends on which way you go. Then unclip the connector and pull sensor out.

The car seem to be making a clicking under a load or when speeding up.
