Exhaust and Intake Camshaft Position Sensors GMC Acadia 3.6L 2007-2016 Location and Replacement

Exact Component Location

This video focuses exclusively on showing you the exact, precise location of the Intake and Exhaust Camshaft Position (CMP) sensors on this vehicle. The 3.6L V6 engine utilizes a total of four camshaft sensors—two for each cylinder bank. If you are struggling to find them, they are located at the rear (transmission side) of the cylinder heads. The front bank (Bank 1, facing the radiator) and the rear bank (Bank 2, facing the firewall) each have an intake and an exhaust sensor mounted into the upper timing or valve cover area, and this visual guide will clear up any confusion immediately.

How This Video Helps Your DIY Repair

Locating all four sensors quickly is the crucial first step for any successful do-it-yourself project. By seeing the exact spot and identifying how the electrical connectors, locking tabs, and single mounting bolts are oriented on both the radiator bank and the tight firewall bank beforehand, you can easily plan your approach, grab the right compact sockets or swivels, save valuable time, and proceed with confidence knowing you are targeting the correct components.

Symptoms of Faulty Camshaft Position Sensors

Failing intake or exhaust camshaft sensors prevent the engine control module from accurately tracking valve timing and synchronizing fuel injection. Common symptoms include an illuminated Check Engine Light (CEL) with specific timing or correlation codes (such as P0340, P0345, P0365, or P0390), extended engine cranking or a hard-start condition, severe engine hesitation and jerking during acceleration, a rough or surging idle, and a noticeable drop in power.

Safety Measures and Precautions

Before beginning any work on your vehicle, it is essential to prioritize safety. Always wear proper protective gear, including safety glasses and mechanic gloves, to protect your eyes and hands from sharp engine brackets, brittle electrical clips, and hidden road grime. Because the sensors on the rear bank require reaching deeply into the back of the engine bay near the firewall, stay alert, ensure the engine is completely turned off and fully cooled down to avoid severe burns from hot engine components or exhaust plumbing.
