P1110 NISSAN - valve location

Question

Hi, I am having problem with my car(Nissan Primera 1.8 1999 CVT, it's QG18DD engine). It does rev while in park or neutral. Also check engine light pop up some time while driving But temporarily it's gone if I shut the engine for a while. Scan shows Code error P1110 (Intake Valve Timing Control Bank 1). Can some one please tell me the location of this device? I have uploaded the engine image and made a lucky guess to figure out the device(Marked as red) http://postimg.org/image/azoxaczst/

If I am correct then what would be procedure to remove the device? If not, help me to locate it and tell me how to remove? Thanks heaps!!!
