Where is the crank position sensor on a 1990 Nissan maxima with the vg30e engine?

OK ...AFTER A LONG OVERVIEW OF BOTH MY MANUALS...I DO NOT SEE A ..."POISTION" SENSOR LISTED......HOWEVER I DO SEE A CRANK ANGLE SENSOR..I BELIEVE THATS WHAT YOU ARE MEANING..IT IS INCORPORATED INTO THE DISTRIBUTOR SYSTEM...YOU CAN LOCATE IT UNDER THE ROTOR IN SIDE THE DISTRIBUTOR ITSELF......ALL THE BEST ..........BUDDY MACK.......THANKS FOR INCLUDING ENGINE INFO AND YEAR...
