Only after fueling the last four times, Ihave had to restart the car several times for it to keep running. I am told he evaporative cannister is full and needs to be replaced. Can this be by passed or mustit be replaced?
Any other suggestions

Re: 04 sonata hard tostart after fueling
Sounds like the 'Purge Control Solenoid Valve' to me. The evaporative canister (charcoal canister) absorbs the vapors from the fuel tank).. sometimes this canister becomes 'saturated' and the 'PURGE CONTROL SOLENOID VALVE' sucks RAW fuel into the intake manifold (causing a 'flooding' fuel condition).. but ONLY if this valve is STUCK OPEN or LEAKING. Replace this valve.. go from there.

I too have had the warning on the dash indicating: "GAS CAP". It is a generic code for anything to do with the fuel cap, filler hose, or overflow, including the charcoal cannister evaporative recovery system. Sometimes it is an easy fix, to simply replace the gas cap. If people consistently twist the cap past the point where it clicks, after closing = it can wear out the cap, and prevent a good seal. However, a large majority of people have overfilled their tank too many times and the evaporative cannister is full and the overflow line is clogged or kinked. Start with the cheap solution first, gas cap.
My problem started after running the extreme obstacle course at Daytona Beach Jeep Beach 2013 at which point I pulled the cannister off the bottom and had to replace it. There are no skid plates protecting it and it would be easy for sticks etc. to get jammed up in and around that cannister while even mildly off road. Crawl under and follow the filler hose down from the passenger rear of the vehicle. The charcoal cannister is approx the size of 2 loaves of bread and sits just forward of the axle, next to the drive shaft.
Filling up the gas tank can stir up the fuel fumes. You may need to check your evap system? I can't rule out bad gas?
When the problem is ongoing, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. With intermittent issues, need to test when problem is ongoing. How long since a tune-up? Any applicable trouble codes?
Problems at higher rpms, the basics, you check for a blockage of some kind, fuel--air--exhaust.
first check gas cap for proper seal. If OK, trace evaporation hose starting at fuel tank and going to evaporation cannister. Check hose for cracks and loose fitting. Check cannister for cracks and also hose from cannister to intake manifold. If no hose leaks or cracks, suspect leaky purge valve.
Let us know if you get stuck or have more questions.
1. Make sure your gas cap is sealing.
2. Inspect the evaporation system hoses and line that goes from the fuel tank to the evaporation cannister, which is probably in the engine compartment
3. Inspect the hose/line going from the evaporation cannister to the engine.
if you mean the evaporator hose for the air conditioner .. then observe under the hood .. you will see two pipes coming from inside the car side by side .. one is large and one is small .. the evaporator is the thing inside your heater compartment that cools the air for air conditioning .. the hoses could be called the "evaporator hoses" . the large hose is the "low pressure" side and is where the refrigerant comes out of the evaporator .. the smaller hose is the high pressure side and thats where fluid under high pressure enters the evaporator
now there is also an evaporitive emission control system on your car .. thats where gas fumes that evaporate inside the gas tank are collected in a charcoal cannister temporarily .. when the car is running those fumes are drawn into the engine and burned along with the fuel ... there is a hose that comes from the gas tank to the cannister and you could call that an evaporation collection hose ..
Hi, the fuel filter is by the front of the gas tank. but the person was right about the strainer on the fuel pump but that is just the first filter to keep large sediments out, and secondary filter is to keep the small stuff out.
I have 2002 sonata H-matic since late it has a severe miss when starting. after starting it runs smoothly but as soon as start for a couple of minutes the mis is there. please help me solve this problem
P0441 - Evaporative Emission Control System Incorrect Purge Flow
The "EVAP purge flow" faults are issues between the carbon cannister and the intake. The EVAP leak detection generally concerns the fuel tank to carbon cannister plumbing.
A little background. The EVAP or evaporative emission system is a control system to keep vapors from evaporation in the fuel tank from getting into the atmosphere. The fuel tank is not vented, but rather the vapors are piped to the carbon cannister (usually located behind the pass. side front wheel) where the charcoal element absorbs the vapor. This is actually a vapor "storage" device. Under certain engine operating conditions, the ECU activates the Cannister Purge Valve (N80) which opens and allows the engine vacuum to **** the fuel vapors back out of the carbon cannister. This purges the vapor, allowing the cannister to absorb more vapor. This evap system has been on vehicles since the '70s.
As part of the OBDII standard effective for 1996 cars and newer, it was mandated that leaks in the systems must be detected and reported as a fault which will set the Check Engine Light (CEL). To detect leaks, the system is pressurized by a pump so that leaks can be detected by a lack of appropriate pressure in the system. If there is a leak, such as a cracked vent hose, loose (or leaky) gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. a code will be set. On the cannister to intake side, leaks are detected by deviations in the idle control system. If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults.
My first recommendation is to closely inspect all the small vacuum lines connected to the intake manifold. The corrugated plastic lines are often the culprits, as well as the fabricate covered vacuum lines. Also consider replacing the gas cap.
Cleaning the fuel line was a good idea although it will need time to take effect. Another related problem could be clogged or stuck fuel injectors. Another thing to do is pull the spark plugs. Old or dirty spark plugs also contribute to engine sluggishness. Lastly, bring the car to an autoparts store that features free diagnostic tests. If there are any error codes stored on the car's computer, it would give you an idea where to look for any electrical problems.
