Evaporative Emissions - Overview: Overview

The EVAP 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 system consists of:

• EVAP canister
• EVAP canister purge valve
• EVAP system leak detection pump with filter
• Fuel Tank Pressure (FTP) sensor and tube
• Fuel tank isolation valve (Tank pressure control valve)
• Fuel vapor vent valve (Refueling valve)
• Easy Fuel (capless) fuel tank filler pipe
