8. ETCS-i (Electronic Throttle Control System-intelligent)
General
In the conventional throttle body, the throttle valve angle is determined invariably by the amount of the
accelerator pedal effort. In contrast, ETCS-i uses the ECM to calculate the optimal throttle valve angle that
is appropriate for the respective driving condition and uses a throttle control motor to control the angle.

9. Dual VVT-i (Variable Valve Timing-intelligent) System
General
The Dual VVT-i system is designed to control the intake and exhaust camshafts within a range of 40
and 35 respectively (of Crankshaft Angle) to provide valve timing that is optimally suited to the engine
condition. This improves torque in all the speed ranges as well as increasing fuel economy, and reducing
exhaust emissions.
*: Oil Control Valve
Using the engine speed signal, vehicle speed signal, and the signals from mass air flow meter, throttle
position sensor and engine coolant temperature sensor, the ECM calculates optimal valve timing for each
driving condition and controls the camshaft timing oil control valve. In addition, the ECM uses signals
from the camshaft position sensor and the crankshaft position sensor to detect the actual valve timing,
thus providing feedback control to achieve the target valve timing.

Construction
1) VVT-i Controller
This controller consists of the housing driven by the timing chain and the vane coupled with the intake
and exhaust camshafts.
The intake side uses a VVT-i controller with 3 vanes, and the exhaust side uses one with 4 vanes.
When the engine stops, the intake side VVT-i controller is locked on the most retarded angle side by
the lock pin, and the exhaust side VVT-i controller is locked on the most advanced angle side. This
ensures excellent engine startability.
The oil pressure sent from the advance or retard side path at the intake and exhaust camshaft causes
rotation in the VVT-i controller vane circumferential direction to vary the intake valve timing
continuously.
An advanced angle assist spring is provided on the exhaust side VVT-i controller. This helps to apply
torque in the advanced angle direction so that the vane lock pin securely engages with the housing
when the engine stops.

2) Camshaft Timing Oil Control Valve
This camshaft timing oil control valve controls the spool valve using duty-cycle control from the ECM.
This allows hydraulic pressure to be applied to the VVT-i controller advance or retard side. When the
engine is stopped, the camshaft timing oil control valve is in the most retard position.

*: The advance and retard sides of the exhaust camshaft timing oil control valve are reverse of the intake
side.

Operation
1) Advance
When the camshaft timing oil control valve is positioned as illustrated below by the advance signals from
the ECM, the resultant oil pressure is applied to the timing advance side vane chamber to rotate the
camshaft in the timing advance direction.

2) Retard
When the camshaft timing oil control valve is positioned as illustrated below by the retard signals from

in the timing retard direction.

3) Hold
After reaching the target timing, the valve timing is held by keeping the camshaft timing oil control valve
in the neutral position unless the traveling state changes.
This adjusts the valve timing at the desired target position and prevents the engine oil from running out
when it is unnecessary.

manual supplement.
• Following the maintenance schedule is mandatory.
• Determine the appropriate time to service the vehicle
using either miles driven or time elapsed, whichever
reaches the specification first.
• Maintain similar intervals between periodic
maintenance, unless otherwise noted.
• Failing to check each vehicle part could lead to poor
engine performance and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
(a) Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
(a) Check that the coolant level is between the "FULL"
and "LOW" lines on the see-through reservoir.
