The canister purge valve is located behind the intake manifold in the engine compartment on the firewall side .It should be a small round solenoid with a wire connector attached.It will have a feed hose from the evap cannister to the purge valve and then to the intake manifold.The evap canister is located on under the vehicle on the right side of the gas tank and is held in place by a bracket.If you follow these hoses it will also get you to the canister purge valve.I hope this helped.
the purge valve canister collects fuel vapor during the time you are driving and releases them back to the intake manifold to burn with air and fuel as you are driving. during the time the car is setting still over night any fuel vapor will go back to purge canister to start again when you drive. location of canister is in front of fuel tank on driverside. hope this will help you!!!!
the canister should be mounted on a bracket in front of the fuel tank, the purge valve is located under the hood, if you find the emission lable under the hood.it should have a pretty good detail of purge valve location
Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications. Damaged, missing or improperly installed fuel filler cap. Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system. Disconnected or cracked fuel vapor hoses/tubes in EVAP system. EVAP canister purge valve stuck closed. Canister vent (CV) solenoid stuck open. Fuel tank pressure (FTP) sensor malfunction. EVAP canister leaking. Fuel vapor control valve tube assembly blocked. Fuel vapor vent valve assembly blocked.
Obviously the gas cap would be the easiest and cheapest thing to fix. Just make sure it is put on correctly and tight. If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material. Hopefully it is the gas cap and you can take care of it yourself. Good luck.
P0441 : Evap. Emission System Incorrect Purge Flow
General Description The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The ECM controls the Purge Control Solenoid Valve (PCSV) to purge any collected vapors from the canister back to the engine for combustlon. This valve is actuated by the purge control signal from the PCM and controls fuel vapor from the canister to the intake manifold. Possible Cause :
● Leakage on hose to PCSV● Defective PCSV
