Construction
1) VVT-i Controller
This controller consists of the housing driven by the timing chain and the vane fixed on the intake
camshaft.
The oil pressure sent from the advance or retard side path at the intake camshaft causes rotation in the
VVT-i controller vane circumferential direction to vary the intake valve timing continuously.
When the engine is stopped, the intake camshaft will be in the most retarded state to ensure startability.
When hydraulic pressure is not applied to the VVT-i controller immediately after the engine has been
started, the lock pin locks the movement of the VVT-i controller to prevent a knocking noise.
2) Camshaft Timing Oil Control Valve
This camshaft timing oil control valve controls the spool valve position in accordance with the duty-cycle
control from the ECM. This allows hydraulic pressure to be applied to the VVT-i controller advance or
retard sides. When the engine is stopped, the camshaft timing oil control valve is in the most retarded
state.

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

Purge VSV
Opens in accordance with the signals from the ECM when the system
is purging, in order to send the vapor gas that was absorbed by the
canister into the intake manifold. In system monitoring mode, this valve
controls the introduction of the vacuum into the fuel tank.
Canister FilterPrevents dust and debris in the fresh air from entering the system.
ECM
Controls the canister pump module and purge VSV in accordance with
the signals from various sensors, in order to achieve a purge volume that
suits the driving conditions. In addition, the ECM monitors the system
for any leakage and outputs a DTC if a malfunction is found.

Construction and Operation
1) Refueling Valve
The refueling valve consists of the chamber A, chamber B, and restrictor passage. A constant
atmospheric pressure is applied to the chamber A.
During refueling, the internal pressure of the fuel tank increases. This pressure causes the refueling
valve to lift up, allowing the vapor gas to enter the canister.
The restrictor passage prevents the large amount of vacuum that is created during purge operation or
system monitoring operation from entering the fuel tank, and limits the flow of the vapor gas from the
fuel tank to the canister. If a large volume of vapor gas recirculates into the intake manifold, it will
affect the air-fuel ratio control of the engine. Therefore, the role of the restrictor passage is to help
prevent this from occurring.
2) Fuel Inlet (Fresh Air Line)
In accordance with the change of structure of the EVAP control system, the location of a fresh air line
inlet has been changed from the air cleaner section to the near fuel inlet. The flesh air from the atmosphere
and drain air cleaned by the canister will go in and out of the system through the passage shown below.

Service Tip
The engine oil in the oil filter can be drained by removing the drain plug and inserting the drain
pipe supplied with the element into the oil filter. For details, refer to the 2006 RAV4 Repair Manual
(Pub. No. RM01M1U).
The engine oil maintenance interval for a model that has an oil filter with a replaceable element
is the same as that for the conventional model.
EG-87
4. Oil Filter
An oil filter with a replaceable element is used. The element uses a high-performance filter paper to
improve filtration performance. It is also combustible for environmental protection.
An aluminum alloy filter cap is used to extend its life.
This oil filter has a structure which can drain the engine oil remaining in the oil filter. This prevents engine
oil from spattering when replacing the element and allows the technician to work without touching hot
engine oil.
