I have a 2001 Hyundi accent everytime I put gas in the tank it takes a long time to fill up. And my check engine light comes on a reads P0441 on my scanner I reset my computer and erased the codes. Within a short time the light comes back on.... Any idea.?????

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.
