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.

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.
