Go to the autozone website at autozone.com and register your vehicle. It's free and you will have access to an online repair manual for your vehicle. The information on the evap system and associated components (like the canister and purge valve) should be there. Hope this helped and best wishes.

If you just want to get through the smog test,they usually allow one monitor test to be incomplete and still pass.
If your area does,clear the codes and fill the fuel tank to the top.The other monitors should run and complete but the fuel tank monitor will not run with a full tank of gas so will not turn on the check engine light related to a tank vac leak.KEEP THE TANK FULL,and go get your smog test!

Service engine soon light came on, replaced gas cap it went off but a week later it came back on, when it try to fuel the truck it spill the gas back out like it is a full tank


One of the most common causes, is blockage in the venting system from fuel entering the vent lines and into the charcoal canister, the fuel gets absorbed by the charcoal canister causing it to swell and block vent lines. the gas tank contains both fuel and air. when you fill it up the gas displaces the air and the air has to go somewhere. but the air that is displaced is full of gas vapor so the gas vapor goes to the vent lines and into the charcoal canister, when the charcoal canister swells up it prevents the air from escaping the tank, canister could be clogged,canister filter may need replacement,electrical connection to the close valve may be open,canisterf might be damaged,purge valve from canister might be clogged,vent hoses might be clogged, the vent hose could be clogged, or the vent hose may have a kink. all this is caused by overfilling the gas tank, getting that last drop of gas in the neck of the fill tube.
good luck!

Check engin light is on showing it is for code#po455 which i fell is for fuel evap.i dont no what it looks like or where it is located thank you


This is a system which should prevent gasoline fumes from escaping into the air. This P0455 could mean something as simple as a gas cap that is no longer sealing but could also mean the a canister full of absorbent charcoal is saturated with liquid gasoline and must be replaced. These are mostly mounted on the fire wall under the hood and will have hoses attached to it. Most look like a simple tin can but can have any shape imaginable. These are supposed to absorb the fumes from your gas tank and then routed via hoses to the intake manifold somewhere between the actual air intake and the engine. They are really intended to last the life of the car but overfilling your gas tank can cause them to be wetted with fuel instead of be exposed only to fumes.
Check your gas cap first; this is the most common cause for this problem and the most common solution is to replace the cap.

You are on the right track, you replaced the vent valve and replaced the vsv valve in the engine compartment that should of solved the problem as long as the correct valves were replaced, i would check for a leak in a hose for the evap system, a smoke test would be a good way, the canister may not be the problem but the valves on the canister, there are a few vsv valves on the canister and also the pressure sensor, the switching valve is very common also, there are so many valves thats why the dealer replacing the canister as an asm, hope this helps also make sure gas cap is good.

Problems fillng the gas tank 2002 Sonata


i just went through that problem

Evap canister / close solenoid and air filter $211- 230.00 in parts

$675- $71.00 at dealships for this small 30 minute task

If no check engine light Evap canister and air filter - fixxes problem 100 %
note:you may be able to get by just replacing air filter- works
rarely

if have check engine- close solenoid and purge solenoid may need replace- you local autozone- like autozone will pull check codes for free

the how to:

Jack car up in rear - behind right rear tire - canister -canister close solenoid & air filter are located in a plastic box with metal strap and one bolt.

Unscrew bolt everything drops down the EVAP CANISTER is held to plastic box by wirer tie . Remove wire tie and solenoid connection.
There is a small metal wire clip the holds the solenoid electrical connection together with a flat screw driver pry up the wire clip , off is okay too , ....it will go back on.

Once you have done all that you have full access there are i believe from memory 3 rubber hoses with clips ......Mark hose connects very important mark the hoses way the going on evap canister with color tape .

Next, remove whole assembly- the solenoid and air filter will come with the evap canister.

Now that have the whole assembly move to your work bench
look to see how the soleniod hook up to the canister and the air filter - now, disconnect the hose to black solenoid and remove the air filter which hook to solenoid and solenoid at same to ......

Next seperate the the solenoid and air filter- you should be air to put your mouth on solenoid and blew air in one hole and out the other- this solenoid is noramlly open- if air dosen't go threw is stuck closed and must be replaced.

same with air filter- this air filter are know for get plugged and should be replaced every 30,000 miles.

Also note: over fill you gas tank , at fill up - can cause the Evap to get liquid gas inside which cause the chorcoal in the filter to swell up and plyug the system up.------ you should when fill up stop pump gas after the auto pump click off on normal work tank and not try to top off you tank.

note: check with your deal for exact wieghts
weigh the evap canister - six pound - replace it- new one is about 4-4.5 pounds - it is just best to replace .The evap holds gas fumes then send to engine so that dosn't vent to

All parts are dealships only -

This is easy fix and normal, for gas fill problems

canister Evap 161.00
canister close solenoid 43.00 may or may not be used
air filter 7.00

not used in this fix- check engine fix use these parts
sensor price ?
purge valve 39.00
canister close solenoid 43.00
