EVAPORATIVE EMISSION SYSTEM

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.
