Variable Valve Timing (VVT) systems represent a big step in engine technology. VVT adjusts the valve timing of an engine based on driving conditions such as speed, load and acceleration. This dynamic adjustment enhances engine efficiency, power delivery and fuel economy while reducing harmful emissions.
However, automotive technicians frequently encounter vehicles with VVT issues caused by poor maintenance and low-quality motor oil. Problems commonly appear with a check-engine light accompanied by sluggish acceleration and reduced power. In many cases, the issue stems from clogged VVT actuators due to degraded oil.
