A-Premium VVT Intake & Exhaust Camshaft Actuator Solenoid Kit — 2.0–2.4L GM Fit with Cam & Crank Sensors

A-Premium's VVT kit includes intake and exhaust camshaft solenoid valves plus camshaft and crankshaft position sensors designed as direct-fit replacements for many GM 2.0–2.4L engines.

If your vehicle is showing VVT trouble codes, rough idle, reduced throttle response, or intermittent stalling, this complete actuator/solenoid and sensor kit gives you the core components needed to restore variable valve timing operation. Each part is engineered to match factory dimensions and electrical connections for straightforward installation on supported Chevrolet, GMC, Buick, Pontiac and Saturn models from the mid-2000s through the 2010s.

Which vehicles and engines will this A-Premium kit fit?

This kit targets a wide range of GM four-cylinder applications. It supports 2.0L, 2.2L and 2.4L inline-four engines across multiple model years and nameplates, so double-check compatibility before ordering.

• Covers Chevrolet: Captiva Sport (2013–2015), Cobalt (2006–2010), Equinox (2010–2017), HHR (2006–2011), Impala (2014), Malibu (2008–2014).
• Includes Saturn: Aura (2007–2009), Ion (2006–2007), Sky (2007–2010), Vue (2007–2010).
• Supports GMC Terrain (2010–2017), Buick LaCrosse/Regal/Verano (2010–2017 ranges), and Pontiac G5/G6/Solstice/Pursuit variations.

What parts and reference numbers are included in the set?

The package groups both intake and exhaust VVT solenoids with camshaft and crankshaft position sensors so you can address multiple fault codes at once. Reference numbers are provided to help confirm interchangeability with OEM units.

• Intake solenoid cross-references: 12655420, 12628347, 12646783, 12578517, 12679099 and legacy refs like 917215.
• Exhaust solenoid cross-references: 12655421, 12628348, 12646784, 12578518, 12679100, plus 917216 variants.
• Camshaft sensor and crankshaft sensor numbers included for easy match-up (examples: 917720, 12577245 for cam; 907799, 12588992 for crank).

How does this kit impact engine performance and drivability?

Replacing worn solenoids and sensors helps the engine control module get accurate timing and position feedback, which supports smoother idle, better throttle response, and more consistent combustion timing. While results depend on overall engine condition, fresh sensing and actuation components reduce the likelihood of timing-related diagnostic trouble codes.

• Improves VVT actuator responsiveness by restoring proper oil control signal to the cam phasers.
• Restores accurate cam and crank position signals to the engine computer for reliable ignition timing.
• Helps eliminate intermittent misfires and rough idle linked to timing or sensor faults.

What should I expect during installation and maintenance?

These components are manufactured to match OEM fit and electrical connectors, so installation is typically straightforward for a technician or experienced DIYer. Use correct torque specifications, clean oil passages before fitting solenoids, and verify engine oil level and quality for reliable VVT operation.

• Direct electrical plug-and-play connectors reduce adapter requirements.
• Clean oil screens and passages to prevent premature solenoid fouling.
• Inspect wiring harnesses and connectors for corrosion or damage before reassembly.

Who is this for: The A-Premium VVT kit is intended for owners and mechanics working on GM 2.0–2.4L four-cylinder engines who need a coordinated replacement for worn VVT solenoids and position sensors. It's a practical option if you want complete coverage of intake/exhaust actuation and both position sensors in one purchase, whether addressing multiple diagnostic codes or performing preventative maintenance on vehicles listed in the compatibility section.
