PURPOSE
The charcoal canister contains activated charcoal granules which absorb and store fuel vapors until they can be consumed during combustion.
OPERATION
A maintenance free, EVAP canister is used on all vehicles. The EVAP canister is located under the vehicle, inside the left frame rail, in front of
the fuel tank (Fig. 2). The EVAP canister is filled with granules of an activated carbon mixture.
Fuel tank pressure vents into the EVAP canister. Fuel vapors are temporarily held in the canister until they can be drawn into the intake manifold.
The duty cycle EVAP canister purge solenoid allows the EVAP canister to be purged at predetermined times and at certain engine operating
conditions.
