Wells 3T1016 Variable Valve Timing (VVT) Sprocket

The Wells 3T1016 Variable Valve Timing (VVT) Sprocket—also known as a VVT actuator or cam phaser—is a toothed wheel mounted on the camshaft designed to optimize engine performance and efficiency. Located on the end of the intake and exhaust camshafts, this precision-engineered component plays a critical role in modern engine management systems.

How It Works:

After the VVT solenoid sends additional oil pressure to the VVT Sprocket, the actuator is able to advance or retard the timing of the camshaft, allowing for finer adjustments of the intake and exhaust valves. These minute adjustments to the valves, which control the flow of combustible fuel and spent gasses in and out of the combustion chamber, can help decrease vehicle emissions and improve fuel economy.

Quality & Engineering:

Wells VVT Sprockets are engineered and thermal-shock tested to match OE parts in fit, form and function. Wells Vehicle Electronics delivers advanced vehicle electronics solutions backed by extensive application information and technical support.

Signs of a Failing VVT Sprocket:

• Making loud rattling or clattering sounds, especially when vehicle first turns on
• Check engine light or VVT-related diagnostic trouble codes
• Reduced engine performance or rough idle
• Decreased fuel economy

This direct replacement VVT sprocket restores proper variable valve timing operation for optimal engine performance, emissions control, and fuel efficiency.
