Description
This course explains everything about Engines Variable Valve Timing System Operation and Diagnostic.
Variable valve timing system have been used on automotive engines for years. This system that generally is named as VVT, it is referred as different names across different brands like CVVT (Continuous Variable Valve Timing) on Hyundai and KIA, VVT(Variable Valve Timing) on Toyota, Lexus, VW, VCT (Variable Camshaft Timing) on Ford, VANOS on BMW. Considering that this system is widely used on many engines and it sometimes causes many different issues for engine operation, understanding the VVT system operation and diagnostic is very important.
Here is the what we have covered:
– A comparison between the fixed valve timing and variable valve timing.
– Variable valve timing system advantages and disadvantages.
– Variable valve timing components and operation.
– How VVT Cam Phaser works and the common causes.
– How to test the VVT Cam Phaser with scan tool and and the bench.
– Oil Control Valve (Commonly Known as VVT Solenoid) introduction, wiring diagrams and diagnostic.
– VVT Solenoid Diagnostic on the Car with Multimeter, Scan Tool and Oscilloscope.
– VVT Solenoid Removal and Bench Test.
– Variable Forced Solenoid Valve (VFS) operating principle on Variable Valve Timing System.
– Electric continuous variable valve timing (E-CVVT) Introduction, operating principle and common issues.
– E-CVVT Diagram and Resetting Procedure with Scan Tool.
– Variable Valve Timing System common fault codes diagnostic guide.
