The Diagnostic Trouble Code table says for P0441 Evap Ctrl System Incorrect Purge:

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 combustion. This valve is actuated by the purge control signal from the ECM and controls fuel vapor from the canister to the intake manifold.
DTC Description

During "test of vapour generation" a new value from the tank pressure sensor is measured and compared with the start pressure at beginning of "test of vapour generation".
The ECM sets DTC P0441 if the pressure signal decrease occurs and the difference is below the predetermined threshold. If same error code is set in the next driving cycle, the ECM illuminates the MIL.

Unfortunately, this is not the 'turn gas cap 3 clicks" fault. Your likely cause is the PCSV valve is sticking in the open position.

Your test inspection procedure is:

System Inspection
PCSV Inspection
1. Ignition "OFF" .
2. Disconnect the hose leading from the PCSV to the intake manifold at PCSV.
3. Using a vacuum pump, apply specified vacuum(Approx. 15 in, Hg) to the manifold side of the valve and verify PCSV holds vacuum.
4. Ignition "ON" & Engine "OFF".
5. Install scantool and select "EVAP PURGE VALVE" on the Actuation Test mode.
6. Activates "EVAP PURGE VALVE" by pressing "STRT(F1)" key.
7. Verify PCSV release vacuum while valve is activating(should hear a faint click from PCSV).
8. Repeat this procedure 4 or 5 times to ensure PCSV reliability.
9. Is PCSV working properly?
YES
? Thoroughly check fuel vapor hoses and hose clamp and replace as necessary. Go to "Terminal and connection inspection" procedure.
NO
? Thoroughly check fuel vapor hoses and hose clamps between PCSV and intake manifold. Repair as necessary.
If OK, test with a new PCSV and check for proper operation. If problem is corrected, replace PCSV and go to "Verification of Vehicle Repair" procedure

I realize you probably do not have a ScanTool, as this is a dealer testing console. You should start by inspecting the hoses and connection to the PCSV.

Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you remove the positive battery connector and let it sit for atleast 5mins. or more before reconnecting it. This will reset the system and can get it back to it's normal operation.
Hope this helps and thank you for using FixYa! Have a good one!

Yes the seal around the gas cap is sucking air take some baby oil and run it around the gaset and put it back on and this should stop.
p.s.
dont remove the gas cap with the engine running or you will set of an evap emmison control sensor.

P0441 code evap for Hyundai Accent 2004


You can clear the code and see if it comes back first.
Code 441 is for incorrect purge flow which means the computer vented the gas tank to the vapor canister and the flow went the wrong direction or there was a vac when there should not have been.
If the code returns a mechanic will need to check the gas tank vent.

2001 toyota 4runner< engine light on, code comes out to be - p0441 auto zone said change gas cap, i did, 2 weeks later light comes on again< what do you think?


You can get this code if you don't tighten the gas cap all the way, or the gas cap is bad. I will put all the detail for the code below and what I would do to fix the problem...

NOTE: Do not top off your tank either. This could cause the 'overfill check valve' to fail, and could cause this code.

Definition of P0441: Evaporative Emission Control System Incorrect
Purge Flow

Detection logic:
DTCs P0441 and P0446 are recorded by the ECM when evaporative emissions leak from the emissions components
or when there is a malfunction in either the VSV for EVAP, the VSV for
pressure switching valve, or in the vapor pressure sensor itself.
detection cause: Pressure in charcoal canister and fuel tank does not drop or
drop in pressure increased beyond the specified limit during
purge control (2 trip detection logic)

What I would do:
1. Replace fuel cap and reset computer. If code returns, then proceed to next

The next steps require a diagram, so the purchase of service manual to locate the components is very helpful

2. Check for vacuum leaks in ALL emission hoses
3. Check VSV valve operation (there are three; they are ~$75 new from dealer, and sometimes fail)
4. Check for cracks or leaks around or in the charcoal canister (usually requires a smoke machine)
5. check for voltage to VSV's
6. Last resort: take it to the dealer and have them run a diagnosis. This should run between $50-$100.

Good luck!

2004 hyundai accent. trouble filling gas tank


I have a 2005 Hyundai Accent, It is not possible to fill the tank if you are letting the petrol pump run at full speed.Trying to fill up quickly it will only build up pressure and cut off. Next time you fill up just pull the petrol pump handle half way, it will take longer to fill but you wont get the blow back. Modern petrol pumps are getting quicker all the time.Hope this helps you.

Car acted like the battery died/cannot fill gas tank.


Evaporator vent silenoid at rear by gas tank is most likely stopped up. Is the check engine light on? If so, take to Auto Zone and get them to scan it for free. Get codes only and post them.

P0441 EVAP Emission Control System Purge Flow Fault 2001 Accent


It is always best to start simple on a lot of these things. This code indicates that somewhere in the evaporative system you have a leak that has set off the code. The gas cap is the most common culprit and that is where I would start. Buy a new gas cap and put it on. It may and should solve your problem. A lot of gas caps have rubber seals that do wear out over time. If this does not solve your problem simply use a search engine and type in p0441 a wealth of information will pop up. There are other possible causes and solutions but that's where I would start (with the gas cap)
