Airtex 3T1146 Engine Variable Valve Timing (VVT) Sprocket

The Airtex 3T1146 is a direct-fit replacement Variable Valve Timing (VVT) Sprocket, also commonly referred to as a cam phaser or VVT actuator. This toothed wheel mounts to the camshaft and works in conjunction with the engine's oil pressure and powertrain control module to advance or retard valve timing, optimizing engine performance, fuel efficiency, and emissions across the full RPM range.

Key Features:

• Direct-fit OE replacement VVT sprocket designed to restore proper camshaft timing
• Engineered to match original equipment specifications for fit, form, and function
• Restores proper valve timing to eliminate rough idle, hesitation, and loss of power
• Helps resolve camshaft position fault codes and VVT system malfunction codes
• Manufactured to withstand the demands of oil-pressure-driven variable valve timing systems
• Replaces worn, slipped, or damaged sprocket teeth that cause timing chain rattle or timing faults

A failing VVT sprocket can trigger check engine lights with camshaft position or timing-over-advanced codes, cause rough idle, reduce throttle response, and produce a metallic rattling noise from the front of the engine. Replacing the sprocket with a quality unit like the Airtex 3T1146 restores the precise valve timing your engine requires for optimal output and efficiency.
