The evaporative emission control system prevents
fuel vapors generated in the fuel tank from escapin g
into the atmosphere.
Fuel vapors from the fuel tank flow through the
fuel tank pressure control valve and vapor pipe/hos e
to be stored temporarily in the EVAP canister.
When the vehicle is in operation, fuel vapors stored
in the EVAP canister flow through the EVAP purge
solenoid and purge port and go into the intake
manifold plenum to be sent to the combustion cham-
ber.
When the engine coolant temperature is low or
when the intake air quantity is small (when the
module brings the purge

intake manifold plenum. This does not only insure

Furthermore, an EVAP ventilation solenoid is locate
between the EVAP canister and the atmosphere
in order to carry out OBD-II EVAP leak monitoring.
This solenoid is normally off, but turns on during
OBD-II EVAP leak monitoring to shut off the flow
of air into the EVAP canister from the atmosphere.

EXHAUST GAS RECIRCULATION
GENERAL INFORMATION
The exhaust gas recirculation (EG system lowers
the nitrogen oxide
emission level. When the
air/fuel mixture combustion temperature is high,
a large quantity of nitrogen oxides is gener-
ated in the combustion Therefore, this
system recirculates part of emission gas from the
exhaust port of the cylinder head to the combustion
OPERATION
When the engine coolant is low, when
the engine is at idle or when a wide open throttle
operation is performed, the EGR valve is kept
closed, achieving no EGR.
The manifold differential pressure sensor is locate d
in the intake manifold plenum. This sensor detects
variations in the manifold pressure when
the EGR solenoid is momentarily operated. If the
manifold negative pressure the EGR sys-
tem is normal.

The EGR flow rate is controlled by the EGR valve
so as not to decrease the
In normal vehicle operation performed after warm-
ing up of the engine, the EGR valve is opened
to carry out EGR.
The ECM uses this to check the operation of the, EGR system. If a problem is found, the check en-’
