Evaporative Emissions
Evaporative Emissions
Overview
The EVAP (Evaporative Emission) system prevents hydrocarbon emissions from entering the atmosphere by storing fuel vapors and routing the vapors to the engine to be consumed during normal engine operation.
The EVAP (Evaporative Emission) system consists of:
- EVAP (Evaporative Emission) canister purge valve
- EVAP (Evaporative Emission) canister
- Dust separator
- EVAP (Evaporative Emission) canister vent solenoid
- Fuel vapor tube assembly (includes the FTP (Fuel Tank Pressure) sensor)
- Easy Fuel(TM) (capless) fuel tank filler pipe
