Standard Motor Products VVT861 Variable Valve Timing Sprocket Cam Phaser

The Standard Motor Products VVT861 is a direct-fit replacement Variable Valve Timing (VVT) Sprocket, also known as a cam phaser. This component is a critical part of the engine's variable valve timing system, dynamically adjusting camshaft timing to optimize engine performance, improve fuel efficiency, and reduce exhaust emissions.

Key Features:

• Direct-fit OE replacement — engineered to match original equipment specifications for a hassle-free installation
• Precision-machined construction — meets tight dimensional tolerances to ensure accurate variable valve timing and correct rough idle
• All-metal integrated machined design — eliminates paddle inserts while providing a larger contact area for improved wear characteristics and proper lubrication
• Improved internal sealing — minimizes oil drain-back and reduces the frequency of PCM correction events
• Reduced friction — allows the sprocket to respond quickly at lower oil pressure for optimal performance
• Extensively tested — undergoes thermal shock, thermal cycling, salt spray, vibration, and dirty oil testing for real-world durability
• OE-matching sprocket tooth profiles — ensures quiet operation and long service life

A failed or worn VVT sprocket can result in rough idle, engine stalling, rattling noises at startup, poor acceleration, and illuminated check engine lights with codes such as P0011, P0014, P0016, or P0017. Restoring this component with a quality replacement brings the variable valve timing system back to proper operation. It is recommended to inspect and replace related VVT solenoids and timing chain components at the same time for a complete repair.
