What is a variable timing actuator?
What is the Variable Valve Timing Actuator (VVT) all about? With VVT, the engine’s timing adjusts minutely during operation to meet the needs at the time, predominantly during mid and peak performance situations. It also helps to provide the smoothest idling, and ensures good “all around” performance.
How does valve timing work in an LS engine?
The computer senses engine load. It also monitors valve timing through the camshaft position sensor. It uses these inputs to determine the best valve timing for the current conditions. The computer sends a signal to a solenoid on the timing cover. The solenoid controls oil flow through a special control valve in the camshaft bolt.
How does a variable valve timing system work?
Variable Valve Timing (VVT) systems are designed to reduce emissions and maximize engine performance and fuel economy. Variable Valve Timing (VVT) systems utilize oil pressurized solenoids and camshaft phasing sprockets to change the timing of a valve lift event throughout the engine RPM range.
Is the actuator on an engine without VVT?
Engines without VVT will not have the actuator. They only have a 3-pin connector for the camshaft sensor. GM used 2 different camshaft phasers. How does it work?
Do you need a cam phaser limiter for VVT?
If you swap your cam and want to keep VVT, a Cam Phaser Limiter is often required. For performance engines, a VVT Delete Kit is recommended. Was this answer helpful?

What kind of camshaft phaser does a Lincoln Navigator have?
2006-2008 Lincoln Mark LT 5.4L 2005-2014 Lincoln Navigator 5.4L Includes 2x Camshaft Phaser Sprockets. Includes 2x Camshaft Phaser Bolts.

How does the variable valve timing system work?
The function of the VVT is to control the open and shut timing of the valves so as to maximize fuel economy. Any malfunction here can cause wastage of fuel or dip in performance. If you notice decreased fuel economy, chances are that the variable valve timing sensor or some other part of the VVT system is failing.
