2. EvaporativeEmissionControl
System (except canister)
Your Hyundai is equipped with an
emission control system.
There are three emission control sys-
tems which are as follows.
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmo-
sphere.
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh air to the
crankcase through the air cleaner.
Inside the crankcase, the fresh air
mixes with blow-by gases, then
passes through the PCV valve into
the induction system.

Exhaust emission control system
If the fuel-vapor vent line is clogged
or damaged, the fuel-vapor mixture
will escape into the atmosphere and
cause insufficient emission control.
Disconnect the line at both ends, and
blow it clean with compressed air.
Remove the filler cap from the filler
pipe, and check to see if there is
evidence that the packing contact to
the filler pipe is faulty. The overfill
limiter (2-way valve) installed on the
vapor line between the canister inlet
and fuel tank outlet must be checked
for correct operation.
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized Hyundai dealer in ac-
cordance with the maintenance sched-
ule in this manual.

PCV Valve
The crankcase ventilation system
must be kept clean to maintain good
engine performance.
Periodic servicing is required to re-
move combustion products from the
PCV valve.
