EVAPORATIVE EMISSION CONTROL SYSTEM
GENERAL DESCRIPTION (EVAPORATIVE EMISSION SYSTEM)M1173005100706
The evaporative emission (EVAP) system prevents
fuel vapors generated in the fuel tank from escaping
into the atmosphere.
Fuel vapors from the fuel tank flow through the vapor
pipe/hose to be stored temporarily in the EVAP can-
ister.
When the vehicle is in operation, fuel vapors stored
in the EVAP canister flow through the EVAP purge
solenoid, purge port and intake manifold plenum to
the combustion chamber.When the engine coolant temperature is low or when
the intake air quantity is small (when the engine is at
idle, for example), the Engine-ECU brings the EVAP
purge solenoid into the OFF state to shut off the fuel
vapor flow to the intake manifold plenum. This
ensures driveability when the engine is cold or run-
ning under low load and also stabilizes the emission
level.

4. If the inner shaft is hard to remove from the transaxle, strike
the bracket assembly lightly with a plastic hammer and
remove the inner shaft.
Do not apply pressure to the wheel bearing by the vehicle
weight to avoid possible damage when the drive shaft is
removed. If, however, vehicle weight must be applied to
the bearing to move the vehicle, temporarily secure the
wheel bearing by using special tools MB991000 and
MB990998.
