* Fuel Tank: This is the starting point, containing the fuel vapor. Obviously, this is under the car, in the rear.
* Evaporative Emission Canister (often called a charcoal canister): This canister absorbs fuel vapors. It's usually located near the rear of the vehicle, often under the car near the fuel tank, but sometimes in the wheel well.
* Purge Valve (or solenoid): This valve controls the flow of fuel vapors from the canister to the engine's intake manifold for combustion. It's generally found near the engine bay, possibly attached to the canister or near vacuum lines.
* Vapor lines/hoses: These connect the fuel tank, canister, and purge valve. These run under the car and through various parts of the vehicle.
* Pressure sensor (or sometimes a sensor within the canister): This monitors the pressure within the system. Its location can vary, but it's usually near the canister or fuel tank.
To locate these components specifically on *your* 1999 Chrysler Cirrus:
1. Consult a repair manual: A Haynes or Chilton repair manual specific to your year and model will have diagrams showing the exact location of each component. This is the most reliable method.
2. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts) allow you to select your vehicle and view diagrams of the fuel system, including the evaporative emission system. These are usually fairly accurate.
3. Visual inspection (use caution): Carefully inspect the area under the car, near the fuel tank and the engine bay. Look for a canister (often black plastic), vacuum lines, and any sensors or valves that might be connected to the fuel system. Be extremely careful when working under a car and use jack stands for safety.
Remember that working on the evaporative system can involve dealing with fuel vapors, which are flammable. Proper ventilation and safety precautions are essential. If you're not comfortable working on the vehicle yourself, it's best to take it to a qualified mechanic.
