Engine Variable Valve Timing (VVT) Sprocket, 7V-1008P (Discontinued)

Your engine’s fuel economy and power depend greatly on complex electronic processes that control precisely when fuel and air are added to the combustion chamber. Your vehicle’s Cam Phaser advances or retards valve timing to optimize for various power and economy requirements. When this unit begins to fail, a ticking noise can sometimes be heard, and a check engine light may illuminate.
