GM GENUINE PARTS Camshaft Position Actuator Solenoid Valve 12732244 — OE-fit, corrosion-resistant

GM Genuine Parts 12732244 is an OE-grade camshaft position actuator solenoid valve that controls oil flow to cam phasers to help maintain the engine’s intended valve timing.

This GM Genuine Parts solenoid is engineered and validated by General Motors as a factory-equivalent replacement for variable valve timing systems. It regulates hydraulic pressure to the cam phasers so the engine’s intake and exhaust camshafts can advance or retard according to speed, load, and driving conditions. Manufactured to rigorous GM specifications, this unit aims to deliver consistent fitment, calibration, and corrosion resistance compared with aftermarket alternatives.

How does this solenoid affect engine timing and performance?

The solenoid meters engine oil to the cam phasers, enabling precise camshaft position changes that adjust valve events. Proper operation helps the ECU achieve calibrated timing maps designed for efficient combustion and driveability. A failing solenoid can cause timing errors, rough idle, or reduced fuel efficiency.

• Controls oil flow to cam phasers for accurate cam timing
• Makes timing adjustments based on engine speed and load
• Designed to match OEM calibration for predictable performance

What are the build and durability features of the 12732244 unit?

This GM Genuine Parts solenoid is coated to resist premature corrosion and built to match the original equipment’s electrical and hydraulic characteristics. GM engineers update materials and designs periodically, and this part follows those validation standards. Installation typically provides the same service life expectations as the factory-fitted component.

• Protective coating against corrosion for longer service life
• OE-calibrated design to ensure consistent response and fit
• Backed and validated by General Motors engineering standards

How do I know this is the right replacement for my vehicle?

GM Genuine Parts are either the original production parts or parts validated by GM for specific Chevrolet, Buick, GMC, and Cadillac applications. Confirm compatibility by matching the GM part number 12732244 to your vehicle’s VIN, year, and engine configuration. Using the correct GM part ensures connector, mounting, and performance compatibility without aftermarket guesswork.

• Match part number 12732244 to your vehicle’s service manual or VIN
• Designed to fit the same mounting points and electrical connectors as OE
• OEM-level calibration helps preserve original engine mapping

What should I expect during installation and maintenance?

Replacement typically involves removing the old solenoid from the valve cover or timing chain area and installing the new unit with the proper torque and gasket or O-ring. Clean oil passages and use manufacturer-recommended oil to prevent contamination. If you encounter persistence of diagnostic trouble codes after installation, have the vehicle scanned and the system cycled per service procedures.

• Install with correct torque and new sealing components as needed
• Inspect and clean oil passages to prevent blockage-related failures
• Use correct oil grade and change intervals to protect variable timing parts

Who is this for: Technicians, DIY owners, and fleet managers looking for a reliable, factory-backed replacement solenoid for GM variable valve timing systems. Choose the GM Genuine Parts 12732244 unit when you need OE-fit, validated calibration, and corrosion-resistant construction to restore proper camshaft timing behavior in compatible Chevrolet, Buick, GMC, and Cadillac engines.
