EVAPORATIVE EMISSION SYSTEM

[QG (WITH EURO-OBD)]

EVAPORATIVE EMISSION SYSTEM

PFP:14950

Description

EBS00QTY

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.

EVAP CANISTER

Check EVAP canister as follows:

Block port B . Orally blow air through port A .
Check that air flows freely through port C .

Block port A . Orally blow air through port B .
Check that air flows freely through port C .

FUEL CHECK VALVE

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.

Blow air through connector on EVAP canister side.
Air flow should be smoothly directed toward fuel tank side.

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)

Wipe clean valve housing.

Check valve opening pressure and vacuum.

If out of specification, replace fuel filler cap as an assembly.

POSITIVE CRANKCASE VENTILATION

PFP:11810

Description

EBS00QU0

SYSTEM DESCRIPTION

This system returns blow-by gas to the intake manifold.
The positive crankcase ventilation (PCV) valve is provided to conduct crankcase blow-by gas to the intake
manifold. During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the
PCV valve. Normally, the capacity of the valve is sufficient to handle any blow-by and a small amount of venti-
lating air. The ventilating air is then drawn from the air inlet tubes into the crankcase. In this process the air
passes through the hose connecting air inlet tubes to rocker cover. Under full-throttle condition, the manifold
vacuum is insufficient to draw the blow-by flow through the valve. The flow goes through the hose connection
in the reverse direction.
On vehicles with an excessively high blow-by, the valve does not
meet the requirement. This is because some of the flow will go
through the hose connection to the air inlet tubes under all condi-
tions.

EBS00QU1

PCV (POSITIVE CRANKCASE VENTILATION) VALVE

With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
