Hyundai Accent (HC) (2017 - 2022) Service Manual: Variable Force Solenoid (VFS)

- Description CVVT (Continuous Variable Valve Timing) system advances or retards the valve opening and closing timing of the intake or the exhaust valve in accordance with the ECM control, calculated by the engine speed and the load. The CVVT control causes a valve over-lap or under-lap between the intake valve and the exhaust valve. This improves fuel efficiency, reduces exhaust gases (NOx, HC) and enhances the engine performance, thanks to reduced pumping loss, internal EGR (Exhaust Gas Recirculation) release, improved combustion stability, and increased volumetric efficiency.

Hyundai Accent (HC) (2017 - 2022) Service Manual: General Information

- General Troubleshooting Information Before Troubleshooting 1.Check applicable fuses in the appropriate fuse/relay box. 2.Using the battery checker (MCR-570 KIT), check the battery for damage, state of charge, and clean and tight connections.(Refer to Engine Electrical System - "Battery")     • Do not quick-charge a battery unless the battery ground cable has been disconnected, otherwise you will damage the alternator diodes.
