Evaporative Emission Control Canister: Description and Operation
EVAP Canister:
The canister protrudes through the top of the bracket. The vacuum and vapor tubes connect to the top of the canister. It is a charcoal canister.
All vehicles use a, maintenance free, evaporative (EVAP) canister. Fuel tank vapors vent into the canister. 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 proportional purge solenoid. The PCM purges the canister at predetermined intervals and engine conditions.
