6. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OUTPUT SIGNAL CIR-
CUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between EVAP canister purge volume control solenoid valve terminal 2 and
ECM terminal 19. Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK (With CONSULT-II)>>GO TO 7.
OK (Without CONSULT-II)>>GO TO 8.
NG >> Repair open circuit or short to ground and short to power in harness or connectors.
7. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT-II
1. Reconnect all harness connectors disconnected.
2. Start engine.
3. Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with
CONSULT-II. Check that engine speed varies according to the
valve opening.
OK or NG
OK >> GO TO 9.
NG >> GO TO 8.
8. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Refer to EC-815, "
Component Inspection" .
OK or NG
OK >> GO TO 9.
NG >> Replace EVAP canister purge volume control solenoid valve.
9. CHECK INTERMITTENT INCIDENT
Refer to EC-570, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
>>INSPECTION END Continuity should exist.

EVAPORATIVE EMISSION SYSTEMPFP:14950
DescriptionEBS01154
SYSTEM DESCRIPTION
The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel
system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister.
The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the
vapor is stored there when the engine is not operating or when refueling to the fuel tank.
The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the
engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the
engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is
proportionally regulated as the air flow increases.
EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and
idling.

Component InspectionEBS01155
EVAP CANISTER
Check EVAP canister as follows:
1. Block port B . Orally blow air through port A .
Check that air flows freely through port C .
2. Block port A . Orally blow air through port B .
Check that air flows freely through port C .
FUEL CHECK VALVE
1. Blow air through connector on fuel tank side.
A considerable resistance should be felt and a portion of air flow
should be directed toward the EVAP canister side.
2. Blow air through connector on EVAP canister side.
Air flow should be smoothly directed toward fuel tank side.
3. If fuel check valve is suspected of not properly functioning in
steps 1 and 2 above, replace it.
FUEL TANK VACUUM RELIEF VALVE (BUILT INTO FUEL FILLER CAP)
1. Wipe clean valve housing.
2. Check valve opening pressure and vacuum.
3. If out of specification, replace fuel filler cap as an assembly.

WATER SEPARATOR
1. Check visually for insect nests in the water separator air inlet.
2. Check visually for cracks or flaws in the appearance.
3. Check visually for cracks or flaws in the hose.
4. Check that A and C are not clogged by blowing air into B with
A , and then C plugged.
5. In case of NG in items 2 - 4, replace the parts.
NOTE:

Do not disassemble water separator.

Periodic MaintenanceELS000AM
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE (QR20DE AND QR25DE PETROL ENGINE)
(Annual Mileage <30,000 Km/year)
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace,.
NOTE:

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.

(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.

(2) Replace the drive belt if found damaged or if the auto belt tensioner reading reaches the maximum limit.

(3) First replace at 90,000 Km (54,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform "I"
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.

(4) Fuel filter is maintenance-free. For service procedures, refer to FL section. MAINTENANCE OPERATIONMAINTENANCE INTERVAL
