EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEM
H010D01A-AAT3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT1. Crankcase Emission Control
SystemThe positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies 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
and into the induction system.
H010A02O-AATYour Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems 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 recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Caution for the Inspection and Maintenance
Test (V6 Vehicle with Traction Control Sys-
tem)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector in the engine
compartment. (2.7 V6 only)
o For more information, see shop manual
(Wheel Speed Sensor).
o After dynamometer testing is completed,
erase the ABS/TCS DTC (Diagnotic
Trouble Code) with a GST (Generic Scan
Tool) or Hi-Scan Pro.
CanisterFuel vapors generated inside the fuel tank are
absorbed and stored in the canister. When the
engine is running, the fuel vapors absorbed in
the canister are drawn into the induction system
through the purge control solenoid valve.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes 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.
H010C01S-AAT2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe 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, pre-
venting the escape of fuel vapors into the
atmosphere.)
