VAPOR CANISTER
There are 2 EVAP canisters on the vehicle. 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.
