The Evaporative Emission Control (EVAP) system is responsible for preventing fuel vapors from escaping into the atmosphere. The EVAP system on the 2005 Dodge Neon consists of several components, including a carbon canister, a purge valve, and a vent valve.
Carbon Canister:
- The carbon canister is located in the engine compartment, near the firewall.
-It is a black, cylindrical container with a charcoal filter inside.
-The charcoal filter absorbs fuel vapors from the fuel tank.
Purge Valve:
- The purge valve is located near the carbon canister.
- It is a small, plastic valve that opens and closes to allow fuel vapors to flow from the carbon canister to the engine.
Vent Valve:
- The vent valve is located on the fuel tank.
-It is a small, plastic valve that opens and closes to allow air to enter and exit the fuel tank.
Other EVAP System Components:
- EVAP Control Module: The EVAP control module monitors the operation of the EVAP system and controls the operation of the purge and vent valves.
- It is located under the hood, near the carbon canister.
EVAP System Operation:
- When the engine is running, the EVAP control module opens the purge valve. This allows fuel vapors from the carbon canister to flow into the engine, where they are burned.
- When the engine is turned off, the purge valve closes. This prevents fuel vapors from escaping from the carbon canister into the atmosphere.
- The vent valve opens and closes to allow air to enter and exit the fuel tank. This helps to maintain the proper pressure inside the fuel tank and prevents fuel vapors from escaping.
