EMISSION CONTROL SYSTEM
G270000AFD
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all emission
regulations.
There are three emission control sys-
tems which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
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.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
G270100AUN
1. 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.
2. Evaporative emission control(including ORVR: Onboard
Refueling Vapor Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel vapors
from escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be
loaded into a canister while refueling at
the gas station, preventing the escape of
fuel vapors into the atmosphere.)
G270201AUN
Canister
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.
G270202AUN
Purge Control Solenoid Valve (PCSV)
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.
