Description and operation
Description

Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the 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 in turn improves fuel efficiency, reduces exhaust gases (NOx, HC) and improves engine performance by reducing pumping loss, generating internal EGR effect, improving combustion stability, improving volumetric efficiency and increasing expansion work.

This system consists of

-the CVVT Oil Control Valve (OCV) which supplies the engine oil to the cam phaser or cuts the engine oil from the cam phaser in accordance with the ECM PWM (Pulse With Modulation) control signal,

-and the Cam Phaser which varies the cam phase by using the hydraulic force of the engine oil.

The engine oil released from the CVVT oil control valve varies the cam phase in the direction (Intake Advance/Exhaust Retard) or opposite direction (Intake Retard/Exhaust Advance) of the engine rotation by rotating the rotor connected with the camshaft inside the cam phaser.

Repair procedures
Inspection
Coil Resistance
1.

Switch "OFF" the ignition.

2.

Disconnect the OCV connector.

3.

Measure resistance between the OCV terminals 1 and 2.

4.

Check that the resistance is within the specification.

Specification: 6.9 - 7.9 Ω [20°C(68°F)]

Valve Operation
1.

Remove the oil control valve.

(Refer to CVVT Oil Control Valve - "Removal")

2.

Check that the valve operates properly when battery voltage is applied to terminals 1 and 2 of the valve connector.

Specification: Operate

Removal
1.

Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.

Disconnect the CVVT oil control valve connector (A).

3.

Remove the installation bolt (B), and then remove the valve from the engine.
