The VVT sprocket is key to an engine's performance and clean running. If a worn one is the cause, signs can include rough running, lost performance or a check engine light, but other faults can look alike. Before replacing it, look around the camshaft area with the engine off and cool for oil leaks or damage, and leave testing of the VVT system to a shop.
