1 General Information
With the following exceptions, MY 2003 VY Series Cab Chassis Emission Control – GEN III V8 Engine information
carries over from MY 2003 VY Series vehicles. For information not contained within this Section, refer to Section 6E3
Emission Control – GEN III V8 Engine in the MY 2003 VY and V2 Series Service Information.
• Emission control canister mounting position.
• Canister vent line routeing.
1.1 Evaporative Emission Control
The evaporative emission control system used on this
vehicle is the activated carbon (charcoal) canister storage
method. This fuel vapour canister (1) is a three port design
and is mounted in a bracket underneath the vehicle.
The canister cannot be repaired and is servi ced only as an
assembly. Periodically check the canister at the time or
distance intervals specified in Section 0B Lubrication And
Service.
The canister is designed to store fuel tank vapour via the
tank vent line (2) and release it to the engine via the canister
purge line (3).
The canister vent line (4) is attached to the chassis.
