CVVT Oil Control Valve(OCV)

2007 > 2.7L V6 GASOLINE >
INSTALLATION
If the OCVs are installed incorrectly, the vehicle may be damaged.
So when installing them, ensure the OCV and harness connector colors match(Components and harness side).

INSPECTION
FUNCTION AND OPERATION PRICIPLE
The Continuously Variable Valve Timing (CVVT) system controls the amount of valve overlap by varying the amount of
oil flow into an assembly mounted on each intake camshaft through PCM control of an oil control valve. This system
uses two oil control valves, one on each bank. An Oil Temperature Sensor (OTS) is used to allow PCM monitoring of
engine oil temperature. As oil is directed into the chambers of the CVVT assembly, the cam phase is changed to suit
various performance and emissions requirements.. 1. When camshaft rotates engine rotation- wise: Intake- Advance / Exhaust- Retard
2. When camshaft rotates counter engine rotation- wise: Intake- Retard / Exhaust- Advance

Variable Intake Solenoid Valve(VIS)

2007 > 2.7L V6 GASOLINE >
INSPECTION
FUNCTION AND OPERATION PRICIPLE
Variable Intake manifold Solenoid (VIS) valves are installed on surge tank (VIS Valve #1) and intake manifold (VIS
Valve #2). These VIS valve #1 and #2 control vacuum modulators which activate valves in surge tank and intake
manifold. These valves are opened or closed by PCM according to engine condition (Refer to below table).

Electronic Throttle System(ETS)

2007 > 2.7L V6 GASOLINE >
INSPECTION
FUNCTION AND OPERATION PRICIPLE
ETC (Electronic Throttle Control) system is electronically controlled throttle device which controls the throttle valve. It
consists of ETC motor, throttle body and throttle position sensor (TPS). A mechanical throttle control system receives a
driver's intention via a wire cable between the accelerator and the throttle valve, while this ETC system uses the signal
from the Accelerator Position Sensor (APS) installed on the accelerator pedal. After the PCM receives the APS signal
and calculates the throttle opening angle, it activates the throttle valve by using the ETC motor. Additionally, it can
handle cruise control function without any special devices.
