Wells Engine VVT Sprocket Variable Valve Timing

The Wells Engine VVT Sprocket, also called a variable valve timing sprocket, VVT actuator or cam phaser, is a replacement part for the camshaft timing system. It mounts on the end of the camshaft. It has two parts: the camshaft timing sprocket and a section that moves independently of it. When the VVT solenoid sends oil pressure to the sprocket, the actuator advances or retards camshaft timing.

Key Features:

• Adjusts intake and exhaust valve timing. Finer valve control can help lower emissions and improve fuel economy.
• Engineered and thermal-shock tested to match OE parts in fit, form and function.
• Direct replacement for a worn or failed factory VVT sprocket.
• From Wells Vehicle Electronics, a brand known for engine management and vehicle electronics parts.

Signs that a VVT sprocket may need replacement include rattling or clattering noises (especially at startup), hard starting, reduced power at higher speeds, and a check engine light. A new Wells VVT sprocket helps restore correct cam timing and smooth engine operation.
