Hyundai Venue (QX): Evaporative Emission Control System / Schematic diagrams

Canister
Canister is filled with charcoal and absorbs evaporated vapor in fuel tank.
The gathered fuel vapor in canister is drawn into the intake manifold by the
ECM/PCM when appropriate conditions are set.
Purge Control Solenoid Valve (PCSV)
Purge Control Solenoid Valve (PCSV) is installed in the passage connecting canister
and intake manifold. It is a duty type solenoid valve and is operated by ECM/PCM
signal.
To draw the absorbed vapor into the intake manifold, the ECM/PCM will open the
PCSV, otherwise the passage remains closed.
Fuel Filler Cap
A ratchet tightening device on the threaded fuel filler cap reduces the chances
of incorrect installation, which would seal the fuel filler. After the gasket
on the fuel filler cap and the fill neck flange contact each other, the ratchet
produces a loud clicking noise indicating the seal has been set.
Description
Evaporative Emission Control System prevents fuel vapor stored in fuel tank
from vaporizing into the atmosphere. When the fuel evaporates in the fuel tank,
the vapor passes through vent hoses or tubes to the canister filled with charcoal
and the canister temporarily holds the vapor in the charcoal.
Removal
1.
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel
Line")

Description
The immobilizer system will disable the vehicle unless the proper ignition key
is used, in addition to the currently available anti-theft systems such as car
alarms, the immobilizer system aims to drastically reduce the rate of auto theft.
Inspection
1.
Loosen the cruise control switch connector.
2.
Check for resistance between terminals in each switch position.
