Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.
By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work.
This system consists of- | the CVVT Oil Control Valve (OCV) which supplies the engine oil to the cam phaser or runs out the engine oil from the cam phaser in accordance with the ECM PWM (Pulse With Modulation) control signal, |
- | the CVVT Oil Temperature Sensor (OTS) which measures the engine oil temperature, |
- | the Cam Phaser which varies the cam phase by using the hydraulic force of the engine oil. |
Blade replacement
When the wipers no longer clean adequately,
the blades may be worn or
cracked, and require replacement.
CAUTION
To prevent damage to the wiper
arms or other components, do not

Disassembly
If the disassembly procedure is complex, requiring many parts to be disassembled,
all parts should be disassembled in a way that will not affect their performance
or external appearance.
