Import Cam Phasing Systems: Variable Valve Timing
One of the ways automakers squeeze more horsepower and torque from an engine is adding variable valve timing (VVT) to the valvetrain.

GM LS V8 VVT System: Oil Flow And Pressure
The CMP actuator system controls the amount of intake and exhaust valve overlap. The engine control module (ECM) can only command the CMP actuator to advance the valve timing from the park position or retard the valve timing back to the park position.
Oil-Related Engine Codes For Variable Valve Timing Engines
Variable valve timing is becoming a standard system on most late-model engines because it offers higher performance from a smaller displacement engine at higher rpms. Oil plays a larger role in VVT systems. They need engine oil not only for lubrication, but also to actuate the camshafts to change the profile of the lobes.
