Wells 3T1156 Engine VVT Sprocket Variable Valve Timing

The Wells 3T1156 is a replacement engine Variable Valve Timing (VVT) Sprocket designed to restore proper camshaft phasing and variable valve timing system function. The VVT sprocket works in conjunction with the timing chain and camshaft phaser to allow the engine control module (ECM) to adjust valve timing based on operating conditions, optimizing performance, fuel efficiency, and emissions.

Key Features:

• Direct-fit replacement for worn or failed OEM VVT sprockets
• Engineered to OEM specifications for precise fit and function
• Restores proper variable valve timing operation
• Compatible with the vehicle's existing timing system components
• Manufactured by Wells Vehicle Electronics, a trusted supplier of engine management and powertrain components

A failing VVT sprocket can cause symptoms such as rough idle, reduced power, poor fuel economy, and diagnostic trouble codes (DTCs) related to camshaft position or timing. Replacing the sprocket with a quality Wells unit helps eliminate these issues and return the engine to factory specification performance.
