OPERATION
This vehicle uses a maintenance-free, Evaporative (EVAP) Canister (1) filled with activated carbon granules. Fuel tank vapors are vented into the
canister where they are absorbed by the activated carbon granules. The canister temporarily holds the fuel vapors until intake manifold vacuum draws
them into the combustion chamber. The Powertrain Control Module (PCM) purges the canister through the pulse-width modulated EVAP Purge
Solenoid (3). The PCM purges the canister at predetermined intervals and engine conditions.
