- Changing Fuel Filler Neck on 2004 Toyota Corolla.
Vehicle was getting evaporative (EVAP) emissions codes DTC MIL P0441, P0442, P0446
EDIT: 4/28/2019
After having it successfully clear the codes and run all the monitors, now the car is back to a P0441 and P0442 error codes. I'll have to figure out what is happening.
EDIT: 8/23/2019 This does seem to have fixed the problem. Initially, I had some error codes again after the repair. but it seems to be working now.

Very good video. Well done with perfect commentary and steady clear video
You are very kind sir.
Good job. Thank you for the video. I have something obstructing fuel when I fill my car and it takes forever filling because the gas station's pump keeps shutting off. This is just what I needed.
Nice video John. My wife's 2003 corolla has been presenting this code for a few years now. I clear it and it'll come back 6 to 12 months later. Because of the age and mileage of the car I think my best bet will be just to keep clearing it so that if the engine light does appear for something substantial I'll find it. My permanent fix will be buying a new Toyota at some point.
Hi John,
Very good video with detail rich.
Hey, thanks
Thank you. I just received those and seeing this gives the confidence to change the part
Thanks. Let me know if I missed anything and we can added to the notes for others.
I couldn't find a good video for this vintage car, so I thought I would try to make one.
Nice video great info and camera work
Thanks for the kind words.
my 98 corolla started throwing the same codes. i've replace cap. clear code w scanner. 3 days later check eng lite comes back. tested vsv. heard it click , so think that's working. kinda rusty under there, so i just suspect its my filler neck, like yours. thanks for vid. of course, would like a smoke test but , ugh, dont wanna pay 100$ of that.
oh, also, i suspect filler neck cuz when i was filling it the 1st time.{ just bought car} the station pump kept shutting off like it was full and i knew there was no way it could have been . never had a car do that, but ive never had a po446 code either, so i think their related.
Best of luck resolving this. It took me a long time and a lot of wasted money and effort until I found the root cause.
That sounds like the fuel tank vapor check valve.those are notorious to have leaks and also go bad if you top off when filling gas.if you have a habit of over filling your tank it can ruin it.
Hello sir whats the name of the hose that has the plastic shield on
The fuel filler neck consists of the large diameter tube for getting gasoline down to the tank, and two separate vent lines that are covered by the plastic panel.
So you didnt have to drop the fuel tank to detach the old or install the new filler neck?
No. I didn't have to drop the fuel tank or drain the tank. I did spill a little bit of fuel when I took off the lower hose.
I deliberately jacked up that side of the car and left the other side low to try to keep the fuel from spilling from the tank.
Perhaps it would be smart to drain the tank, or at least not working on a full tank.
I did keep a fire extinguisher near by as there was a lot of fuel vapor.
Of course, if you are a smoker, don't do that near the tank.
Thanks for putting together this video. It takes time. So I have been having one of the evap codes and I have replaced the gas cap a few times. Last night I pressured the vent system, the fuel tank and canister. I had to plug a couple lines etc. And the canister. To my dismay when I was spraying some sort of water bubble solution to find leak I found the back of the fuel tank on top where a large vent or vacuum line that goes to the canister was bubbling big time. Just letting you know what I found. I just have to figure out how to fix the fuel tank or replace. Cheers.
I think I saw another video where a gasket into the fuel tank had gone bad and made a leak. Hope you resolve the issue.
Excellent very detailed instructions. You explain it in and understanding way.
question. When you remove the fill hose pipe from the gas tank, what stops the gas from pouring out from the gas tank?
Thank you if anyone could answer this, would be greatly appreciated.
I believe there is a check valve that allows in and not out.
Thanks for the video. I have a 2002 Corolla and the error code P0440 came on. I could smell gas vapors, but I could not get the car into the shop for a couple of months. I did and they got the check engine light off, but I still smelled gas when I pulled out. My car was on empty. I filled it up and quickly found gasoline dripping out just in from the left back tire. When I parked on flat ground it stopped leaking.
I took it back in and they want to charge $1,000 for repairs. They say they ordered a kit which includes these parts - : Fuel
ring, cap assy, shield fuel, hose for upper neck, lower fill hose, Rigid pipe filler, fuel hose. - for $418.
And labor at $450 as they say they have to empty and remove the gas tank.
Does this sound reasonable?
Seems a bit high. I don't know why they would need to remove the gas tank. I certainly didn't do that.
Hello! Aside from the engine codes did you experience and symptoms or did anything change with the cars drivability after changing? Thanks! Great video!
No symptoms or problems
It’s common to smell/see gas in the vicinity as we do now.
Did the error code end up clearing up? Also, how did you empty the gas tank? Was it just driving until it was basically empty? I’m getting ready to do this in a few weeks as I got the error code today and started researching. Thanks so much for this!!!!
Sadly, I still do occasionally get the error code, but it is much less frequent. There is no doubt that my fuel filler next was "a" problem, but it might not be the only problem.
I did not empty the gas tank. The tank was not full and the back end of the car was jacked up. A little gasoline spilled out when I disconnected the lower hose, but not much.
Good luck with your repair.
@@johnbriggs7514 Thanks so much for the info John. People like you who make this content are literally the pillars that hold up UA-cam and make it awesome. Best of luck!!
I need to do replace this on a 2007 highlander, i hope is easy
where did you find the fuel filler neck?
It is Toyota part number 77201-12750 and I purchased it on like at ToyotaParts. Just google the part number
Nice video John all what i need it for my echo toyota 2001
Glad it helped. It does seem to have finally fixed my 2004 Corolla. I've had those errors for years. So happy they are gone.
Similar issue on my 2003 Sequioa. Toyota's are NOTORIOUS for their rubber lines to crack and cause issues on EVAP and vaccuum connections. I replaced every single one under the hood, many were very cracked at the ends and you couldnt see them unless you removed the hose. I replaced the vsv valve at the Evap Charcoal canister, it went away for about a week and then came back. I will be doing the soapy water test next.
These codes passed Texas Emmissions tests last year, same exact code (446), but this year it failed. Was told Texas has changed their requirements to be closer to Cali standards. Great......
Sorry you are having those issues. The rubber lines on mine were fine. But once I finally fixed the fuel filler neck, the codes finally went away
@@JohnCBriggs Thanks! I am going to check those as well. Been trying to chase these codes for a year now.... Didn't think to check that.
@@user-ym9wb2mk5e it took me a year as well :)
Bummer!! So sick of these emissions tests
Did those codes goes go away (or not come back if you cleared them)?
John Anthony. If I cleared the codes with the ODB2 port, they would come back after a while. The evaporation test needs a number of conditions before it is run by the car computer. I could go a week without the test being run.
After the repair, the codes have permanently gone away.
What about change the gas full neck to a 78 ford thunderbird? Please if someone knows how to do let me know thank you
I would appreciate if anyone could answer this. When you remove that hose pipe from the gas tank, what stops the gas from spilling out?
I do not know the anatomy of that. Is there a risk of the gas pouring out when you remove that hose pipe from the gas tank for replacement of the hose pipe?
Notice that the car is jacked up only on the driver's side. This move the gasoline away from the filler neck and I had only minimal gasoline spill out. Also the gas tank was not full.
FWIW. Recently I also had to have the gas tank changed out because there was rust on it as well.
@@johnbriggs7514 John, Thank your speedy response. Much appreciated!
Does it make a difference if car is a 2003 or 2004 Toyota Corolla ?
No. Looks like 2003-2006 are the same. www.toyotapartsdeal.com/oem/toyota~pipe-sub-assy-fuel~77201-12750.html
my car has the exact same three codes. Local mechanic thinks it is a charcoal canister. Will be searching for a second opinion.
Their databases say it is most likely the charcoal canister, but that is only because it is the thing most often replaced, not the right thing. It is a flawed system.
I replaced the canister, which did seem to have at least one issue, but it didn't clear the problem.
Hi... I can not connect with ecu on my 2005 Toyota Corolla Altis 1.8... when it try to connect to ecu the abs light start blinking... Each and every time... I tried different odb 2 devices and many apps on mobile device too... And same devices connect with my 2010 Toyota Corolla 1.3 very easy... Will you help me plz
Mb Barham. I'm sorry I don't know what is happening with that. Sounds very frustrating.
All the way .. thanks to reply... I tried all methods... Disconnected abs by relay and connector... And things too... But nothing works... As I will get any solution... I will share with you...
@@mbbarham2523 MB. 2005 Corolla have a recall on the ECM. My 2005 corolla was throwing all sorts of codes until i got the ECM replaced from toyota and that solved most of the codes except for the EVAP. Turns out i had a broken line. Replaced the EVAP which solved the issue
Did you do a smoke test?
At time marker 0:43 you can see the before smoke test. But I didn't do one after, and it is still throwing codes. No doubt the filler neck leaked, but I either installed it poorly or there is another issue.
@@johnbriggs7514 I heard you replace the Canister, but I have a question... Are you sure the VSV valve is operating 100%? If yes... Did you solve the issue?
Thanks for this great video!
How much the fuel neck costs?.....my car is throwing p0446 alone...any suggestions?

@@johnbriggs7514 OUCH!
@@rocknrollermann Yep. not a cheap part. There might be an aftermarket one that is less expensive.
