A camshaft actuator solenoid is typically installed in the front of each cylinder head and is used to precisely control the flow of oil into the camshaft actuator. This adjusts the rotation of the camshaft to modify valve timing and valve overlap dynamically. These solenoids control both exhaust and intake camshafts, enabling improved engine performance, fuel efficiency, and compliance with emissions standards.This solenoid valve is compatible with the following vehicles: Buick: 20102015 LaCrosse, 20112015 Regal, 20122015 Verano Chevrolet: 20122015 Captiva Sport, 20062010 Cobalt, 20102015 Equinox, 20062011 HHR, 20082014 Malibu, 20122014 Orlando, 2014 Impala GMC: 20102015 Terrain Pontiac: 20072010 G5, 20062010 G6, 20062009 Solstice, 2006 Pursuit Saturn: 20072009 Aura, 20062007 Ion, 20072010 Sky / Vue with 2.0L, 2.2L, or 2.4L engines OE part numbers: Intake Solenoid: 12655420, 12628347, 12646783, 12578517, 12679099, 917215, 917-215, 2T1014 Exhaust Solenoid: 12655421, 12628348, 12646784, 12578518, 12679100, 917216, 917-216, 2T1015 Please verify the OEM replacement number before ordering.This solenoid may help resolve issues related to diagnostic trouble codes P0010 (intake side circuit malfunction), P0011 (intake side actuator solenoid timing over-advanced), P0013 (exhaust side circuit malfunction), and P0014 (exhaust side actuator solenoid timing over-advanced), potentially restoring normal engine operation and driveability.Each camshaft position solenoid actuator is built to meet original equipment specifications and serves as a direct replacement for the intake and exhaust camshaft position actuator solenoid valve. It is designed to fit, function, and appear identical to the original component. Constructed with precision-machined parts, this solenoid provides reliable performance and durability.
