2006 Infiniti M45 Camshaft Position Sensor

Hello. Can someone tell me where to locate the Camshaft Position Sensor on a 2006 Infinity M45? Service Engine light came on after the car stalled out. AutoZone pulled a code PO340 for the Camshaft Position Sensor. I've purchased the replacement part but need to know where it is located on the engine. Thank you very much!
