How does the VVT work on a GM engine?
They also have a 5-pin connector for the VVT and camshaft sensor. 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? The computer senses engine load. It also monitors valve timing through the camshaft position sensor.
What kind of intake cam does a VVTi use?
The vvti has a different Intake cam/cam gear (As it’s VVTi!) Aftermarket cams are available for the VVTi such as HKS’s Valcon system yet they are expensive, a custom grind is probably a more viable option. Link to HKS Valcon Unit: http://www.hks-power.co.jp/products/…on/valcon.html
What does variable valve timing ( VVT ) mean?
Variable Valve Timing (VVT) is a system that automatically adjusts Valve Timing. **The table below shows the engines that were originally equipped with VVT.**
What do you need to know about a VVT solenoid?
There’s a lot of confusion surrounding VVT solenoid operation, as well as the symptoms associated with a bad VVT solenoid. That’s why we’re here to shed some light on the subject. A VVT solenoid applies oil pressure to activate the mechanism that adjusts valve timing (usually an actuator at the end of the camshaft).
Can a check engine light be a VVT fault?
So, this can hurt engine performance; fuel economy and emissions. Also, turning on the check engine light; setting a (VVT)-related fault code. Consequently, any codes could be the result of; a bad cam phaser, oil flow control valve or wiring fault. So, don’t jump to any conclusions; regarding the variable valve timing (VVT) system.
Cam Changing (VVT) Camshaft Phasing (VVT) Cam Changing + Cam Phasing (VVT) (VVC) System ( Unique To Rover ) (VVT) – Variable Valve Timing. So, in theory, maximum overlap is needed; between intake and exhaust valves opening, at high speed. However, when the car is running at medium cruising speed; maximum overlapping may also be useful.

What kind of noise does a VVT make?
When this happens, you may hear a rattling noise or ticking noise from the engine. Some automakers (e.g. Ford) have technical service bulletins (TSBs) for this concern.
