What does a VVT sprocket do?

Located on the camshaft, VVT sprockets (also known as cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency. Remove the entire camshaft.

How much does it cost to fix cam phasers?

Replacing cam phasers is not cheap. You can expect to pay anywhere from $800 to $2500 to get the job done by a professional.

What is the advantage of variable valve timing?

Top 4 Advantages Better Engine Performance. When you put more demand on your engine, it needs to have more revolutions per minute (RPM). Better Gas Mileage. Without variable valve timing technology, an engine must work harder and consume more fuel just to satisfy the demands being placed on it by the driver. Reduced Carbon Emissions. Higher Engine Longevity.

How does variable valve timing improve performance?

The variable valve timing systems are seen in the internal combustion chamber of an engine. It does the job of changing the timing of a valve’s opening and closing and works together with the valve lift system. This component is important because its proper use can enhance engine performance, increase fuel efficiency, and reduce emissions.

How does VVT-variable valve timing work?

Variable Valve Timing (VVT) is a way to advance/retard valve timing, and change duration, overlap and even lift in some applications while the engine is running. VVT is computer-controlled and typically uses oil pressure to change the position of a phaser mechanism on the end of the camshaft to advance or retard cam timing.

How do you replace a variable valve timing solenoid?

Replacing a variable valve timing solenoid is much easier, and can be handled by an experienced do it yourselfer. You can access the solenoids by removing the timing cover. Then you can disconnect the solenoid wiring harnesses, and remove the bolts that hold in the solenoids. Then you can simply pull the solenoids straight out.
