Please..someone tell me where the "CAMSHAFT POSTION SENSOR " IS LOCATED ON MY 2011 BUICK LUCERNE CXL 3.9 LITER. I'VE BEEN THROUGH EVERY YOUTUBE VIDEO, HAVE CALLED AUTOZONE, O'REILLY'S, ADVANCE AUTO & POSTED ON FB. NO ONE SEEMS TO KNOW WHERE ITS LOCATED. IM TRYING TO FIX IT MYSELF. CANT OFFORD A TRUE MECHANIC..PLEASE HELP ME..LOST IN TEXAS!🤔

 

This should be about right. Don’t confuse camshaft with crankshaft sensor. Also may have non-changeable geared section of sensor but not meant to remove- sensor should be phenolic piece with wires (socket) only.
