FUEL FILLER CAP 

DESCRIPTION 

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 filler neck flange contact each other, the 
ratchet produces a loud clicking noise indicating the seal has been set.

2008 ENGINE PERFORMANCE

Evaporative & ORVR Emission Control System - Sedona 

DESCRIPTION 

On-Board Refueling Vapor Recovery (ORVR) system is designed to prevent fuel tank vapor (HC) emissions 
during refueling at the gas station. 

This system consists of a fill vent valve, fuel shut-off valve, fuel cut valve (for roll over), two way valve 
(pressure/vacuum relief), fuel liquid/vapor separator which is installed beside the filler pipe, charcoal canister 
which is mounted under the rear floor LH side member and protector, tubes and miscellaneous connections. 

While refueling, ambient air is drawn into the filler pipe so as not to emit fuel vapors in the air. The fuel vapor 
in the tank is then forced to flow into the canister via the fill vent valve. The fuel liquid/vapor separator isolates 
liquid fuel and passes the pure vapor to the charcoal canister. 

While the engine is operating, the trapped vapor in the canister is drawn into the intake manifold and then into 
the engine combustion chamber. According to this purge process, the charcoal canister is purged and recovers 
its absorbing capability.
