The  emission   control  system   of  your
vehicle  is  covered  by  a  written  limited

Your  vehicle is  equipped  with an  emis-
sion control system  to meet all emission
regulations.

Emission
Control
•  To  prevent the  vehicle  from misfir-
ing   during  dynamometer   testing,

Canister
There  are  three  emission  control   sys-
tems which are as follows.
Fuel  vapors  generated  inside   the  fuel
tank  are   absorbed  and  stored   in  the
onboard  canister.  When  the  engine  is
running, the fuel  vapors absorbed in  the
canister  are  drawn into  the  surge  tank
through the purge control solenoid valve.

Crankcase emission control
system
The  positive  crankcase  ventilation  sys-
tem is  employed to  prevent air  pollution
caused by  blow-by gases  being emitted
from the crankcase.This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh  air  mixes with  blow-by gases,
which then  pass through the  PCV valve
into the induction system.
Purge Control Solenoid Valve (PCSV)
In order to  assure the proper function  of
the  emission control  systems,  it is  rec-
ommended   that   you   have   your   car
inspected and  maintained by an  author-
ized HYUNDAI dealer in accordance with
the maintenance schedule  in this manu-
al.
The purge control  solenoid valve is con-
trolled  by   the  Engine  Control   Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es  so that  evaporated fuel  is  not taken
into the engine. After  the engine warms-
up  during   ordinary  driving,  the  PCSV
opens to introduce evaporated fuel to the
engine.
