The engine may also idle roughly or stall unexpectedly because the variable valve timing cannot synchronize properly with the combustion cycle. Without a functioning solenoid, the engine management system cannot adjust the valve timing, leading to a significant drop in performance and potential damage.
Check Engine Light and Diagnostic Codes The most immediate indicator is usually the illumination of the Check Engine Light. This small yet vital component is responsible for regulating the flow of hydraulic pressure to the valvetrain, ensuring that the engine receives the proper lubrication and hydraulic pressure for the variable valve timing mechanisms.
