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 met.
Purge Control Solenoid Valve (PCSV)
Purge Control Solenoid Valve (PCSV) is installed in the passage connecting canister
and intake manifold. It is a duty cycle controlling solenoid valve 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 gaskets
on the fuel filler cap and the filler neck flange contact each other, the ratchet
produces a loud clicking noise indicating that 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 from the fuel
tank, the vapor passes through vent hoses or tubes into canister filled with
charcoal and the canister temporarily holds the vapor in the charcoal...

because the LKA system may not recognize
that the driver has their hands
on the wheel...
Odometer
The odometer indicates the total distance
that the vehicle has been driven
and should be used to determine
when periodic maintenance should
be performed.
Range
The range is the estimated distance
the vehicle can be driven
