A camshaft actuator solenoid is typically installed in the front of each cylinder head. It controls the flow of oil into the camshaft actuator, adjusting the rotation of the camshaft to optimize valve timing and valve overlap dynamically. These solenoids manage both exhaust and intake camshafts, enabling improved engine performance and fuel efficiency while meeting emissions requirements. This solenoid valve fits the following vehicles: Buick: 2010–2015 LaCrosse, 2011–2015 Regal, 2012–2015 Verano Chevrolet: 2012–2015 Captiva Sport, 2006–2010 Cobalt, 2010–2015 Equinox, 2006–2011 HHR, 2008–2014 Malibu, 2012–2014 Orlando, 2014 Impala GMC: 2010–2015 Terrain Pontiac: 2007–2010 G5, 2006–2010 G6, 2006–2009 Solstice, 2006 Pursuit Saturn: 2007–2009 Aura, 2006–2007 Ion, 2007–2010 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 compatibility with your vehicle using the OEM part numbers before purchasing. This solenoid may help resolve Check Engine Light issues related to diagnostic trouble codes P0010 (intake side circuit malfunction), P0011 (intake side timing over-advanced), P0013 (exhaust side circuit malfunction), and P0014 (exhaust side timing over-advanced), restoring proper engine operation. Each camshaft position solenoid is built to meet original equipment specifications. It serves as a direct replacement for the factory intake and exhaust camshaft position actuator solenoid valves, ensuring proper fit, function, and appearance. Constructed with precision-machined components, this solenoid provides reliable performance as a replacement option.
