Jeep 5184150AF Valve-Oil Control

The 3.6L V6 in 2012 and later models features a Variable Valve Timing (VVT) system that independently adjusts the timing of all four camshafts through solenoids and oil control valves, which manage oil pressure to the camshaft phaser assemblies located at the front end of the camshafts behind the VVT solenoids. Each phaser is equipped with an Oil Control Valve (OCV) that secures the phaser to the camshaft; the OCV spool valve is spring-loaded and moves freely within the OCV, with all OCVs being identical in design but needing to be reinstalled in their original locations. To replace the VVT solenoids, first disconnect the negative battery cable and remove the engine cover. For the driver's side solenoids, the throttle body must be removed, along with two nuts and three bolts, allowing the upper intake manifold support bracket to be moved aside. For the passenger's side solenoids, detach the heater core tubes from the valve cover after removing two nuts. Locate the VVT solenoids on the front of the valve covers, marking their positions if they are to be reinstalled. Disconnect the electrical connectors of the solenoids, remove the bolts, and pull the solenoids out of the valve cover, ensuring to twist them out if Torx screws are present. Inspect the O-ring for damage and replace it if necessary. Reinstallation follows the reverse order of removal, ensuring the solenoids are placed back in their original locations. Finally, perform the cam/crank variation relearn procedure using a scan tool; while the vehicle may operate without this procedure, it is recommended to complete it as soon as possible by a qualified technician or repair facility.
