Default check engine light??? P0455

i have a code P0455 Evaporative Emission Control System Leak Detected Large Leak Detected. i have replaced the gas cap with a new one from auto zone who scanned the engine code for me. any other idea what i should do. they gave me a list on what to check.

1) defective, loose or missing fuel cap (already replaced)
2)EVAP canister broke, hose cracked or not connected
3)Purge or vent solenoid defective
4) Vacuum leak at engine

I don't know where to find these thing EVAP canister is or the purge solenoid, or vacuum leak at engine. This is my first america car and i know nothing about them but would like to learn. any help would be greatly appreciated. Thanks in advance.

DH:

The new gas cap was a good start. I just replaced min at 74k to cure a reccurring p0442.

You will find the evap cannister below near the T case on a cross member. I will bet $20 you will find one or both hoses cracked there.

This is what I found about 6 months back when I had my p0455. You can either buy the assembly at the dealer for ~$40. or go to the local AZ and get a couple of heater bypass hoses for $20.

well before i bought the new gas cap i had code po442 also. so now i just have that one code coming back. took a look at the canister and hoses and the hoses seems fine with no cracks. i think i just might replace the whole assembly just to be on the safe side. but thanks for the advice.

Gas cap is good start. One thing i observed when I was having these recurring codes, was actually a few things. 1. The hoses attaching to the canister, at least one of them was a flared fittinf meaning 3/8th on one side 7/16th on the other I got mine fixed using a length of each size and a coupler and hose clamps. The lengths of hose I got were very short lengths maybe 6" at most per segment, AutoZone gave me them for scrap hose but I had to pay for the couplers, and clamps. One more area to check is off the PCV valve there is a hose that runs into a plastic tube across the manifold and connects with another piece of 90 degree elbow in the back of the engine drivers side between the firewall and engine, that elbow was split. Check both pieces of vacuum hoses both on the engine and pcv valve side. Really check the hoses good, mine were dryrotted and split at the fittings. Might be a good thing to check prior to a long road trip, saves some embarrassment while out on the road. Even with the codes, my 4.7 fine, just a nusciance and distraction and possibly a slight fuel mileage drop but fuel drop is negligible. GoodLuck!!!!

Guys:

Add to this the short section of 5/16" hose that goes from the evap cannister to the fuel tank.

800 miles after replacing the gas cap and having no CE light, yesterday it comes on.
Found the aformentioned hose cracked, so hopefully this is the fix.

i think there is an outline of what it connects to and in what order on the underside of your hood or at least mine has one check there as long as the truck hasnt been repainted it should be there and visible

Did you guys reset the codes after doing these repairs? My wife has left her locking gas cap loose before and once I tightened it, Autozone reset it. (They're not supposed to though).
Which fuse can I pull to reset the computer? Another post said fuse 23, but mine has no fuse 23.
I'm tempted to remove the battery cable to reset it.

Last time this happend, they did it for me after I went and tightened the gas cap then and there. he said they're not supposed to though. This time, they wouldn't do it. Guess they're cracking down. I'll go up the road and try another one.

One other tidbit=don't over fill the gas tank=top it off=gas will get down into the canister and play havoc sometimes=girlfriend did that and the dealer socked for a new cannister= unplug the hoses let the canister air out and try reseting the code after you put all the hoses back on. The solenoid should be running of a hose on the throttle body. It could also be the leak detection/cannister vent valve=the largest hose on the cannister looks like it connects to it=maybe stickin open.

definitely not a stupid question
It is a filter that I use in line with the pvc to filter out all the oil vapors that get sucked back into the intake once I get my camera back from my sis on vacation I'll post the new pic of how much oil has built up since my first pic.
For anyone that remembers the first pic the oil build up was not to bad wait till you see the new pic
