Wow, you're a prophet. I had this issue with my lexus es330, got a new gas cap, brought it to the dealer, who reset the check engine light because they couldn't find the problem. Got a whole new exhaust system, which it probably needed anyway, light came back on, bought a code reader, googled your code, watched your video, no cracks, then got my wife's make up mirror, and had the exact same crack in the hose which I could not see without the mirror. Thanks a lot!
Same problem found on a 2001 Toyota 1mz-fe V6. Same exact location. You are the man! P0442, P0440 solved! Too bad I replaced all sorts of solenoid switches, purge valves and vacuum lines before I ran into your video, but better late than never. Guys, the part is know as "vent hose #2" on various Toyotas.
'04 Sienna here. I got my van back from a transmission repair with the VSC and Check Engine light on. The scam repair guy said he would charge to diagnose. I replaced the gas cap and the lights went off for about 6 months. Now they're back on with some performance/acceleration issues. Thank you for this. I'll be grabbing that mirror and checking my hose myself.
Your video is spot on. I followed it blindly though could not see any cracks but taped the area and put vaseline on gas cap. 2004 lexus ES330 and problem is solved. Over 500 miles and multiple starts light never came back. This issue had been haunting for over a year. Thanks for posting it.
Same here on my 2003 es300....crack on the same place showed in the video....I have p0440 , p0441, p442, p0446 codes ....already tape was there...I redid it now....will see after some time....will post again hoping codes will go off
Try and avoid using petroleum jelly (vasoline) on rubber seals. It tends to degrade them rather quickly. Go with silicone o-ring grease (easily available at your pool supply store).
did not know that.. thanks for the info.. hopefully others will read this and avoid my mistake.. will go with silicone o-ring grease for future needs..
@@tongo117 Thanks for the video. I grabbed a mirror from Advance auto for $2 and sure enough....hose split right in the same spot. I wasn't in the mood to replace it right now so I wrapped it with several turns of self-fusing silicone tape (rescue tape) and dabbed a little silicone grease on the metal tube to help it seal. So far so good...no codes.
You sir, are a god. I have a 2004 camry, and havent been able to find a single video covering the same engine type as mine, yours matches spot on, and leading me to that line, i inspected the surrounding ones. Found a cracked tube not even a foot away from the one you had. Ive spent a week trying to find this leak. Youre the best!
I found a crack in my vacuum hose (I have a V6 2004 Camry LE), but it was for the hose below the one you showed (to the right side of where the spark plugs are). I just put electric tape around it until I eventually get a hose replacement. I had both p0442 and p0456 codes on mine. It's been driving me nuts because I have already replaced the purge valve and gas cap and I kept getting the codes (I do not want to waste money replacing a charcoal cannister if it's not necessary). Here's to hoping the codes don't come back! Thanks!
Thank you for this! I have a P0456 code on my Lexus ES300 (3.0L V6), very small leak. So the first thing I am going to do is replace the gas cap gasket and then check that hose as you suggested. A mirror is a great idea as you're right that you would have never noticed the crack without one.
I can confirm that it fixed my Highlander 2005 too. There was a crack on hose connector at the same spot as shown in the clip. I bought the new assembly of connector and replaced it. It works!
Great insight. Found a fineline crack on upper part of this hose. Got p0174 and p0171 codes after getting a mechanic to change sparks and coils which required moving upper plenum, about 6 months ago. Couldn't figure it out since. I'm going to tape this and check.
Found crack in that exact same place on my 2007 Solara using the flashlight and mirror. Also had a crack in the rubber hose on the other end that short metal tube. Thanks for this video.
I have a 2004 Sienna with the same 3.3L engine and my hose is split at the same spot. I fixted it with electrical tape as well. Thanks. I started my car and it didn't clear automatically. I shut it off and restarted it and it cleared without using the code reader to clear.
PeanutButterMan is this hose causing black smoke and engine shaking ??? Because i want to buy same this car lexus es300 2004 with same this problem ... there is smoke first starting engine when it is cold ... after few seconds the smoke left and disappear
@@RrRr-th1kf This did not cause smoke.. The car ran fine with this issue.. Only way I knew I had a problem was the check engine light and trouble code..
PeanutButterMan there is one person here write comment his name is Jim... he said this hose is called fuel vapor feed hose ... i dont know why I’m sure this hose cause smoke 💨 during cold starting ... after that every thing is ok 100% and there is no check engine in dashboard in my car
OMG. Thanks so so so much for this video. I was afraid I was gonna have to rip my car apart to find a freaking vacuum leak. Lo and Behold, my Rx330 had a cracked hose in the exact same freaking spot! You probably save me a few hundred dollars since I didn't take this to the shop. Thanks again. You rock! :D
Thanks a bunch, this is my problem on my RX330. I have been trying to solve the problem for 6 months. Now I just need to find the part, it is different shape from your part. Very helpful.
I have a 2006 Highlander AWD,V6. My VSC light is also on. Code detects issue with EVAP system. Car emits strong fuel vapors. Gas cap changed ( original Toyota part). I check the vacuum hose as per your video using a mirror and the entire hose is intact. Any other possible causes? Much appreciated.
My leak was coming from the line on the little solenoid mounted to the intake box. Any chance you know what that component might be called so i can look into getting a new hose?
Sorry I do not know the name of that part.. But if you take the section of hose to any auto part store they should be able to match the hose size/length..
My engine looks different, I hv an 2008 es 350, could you pls help me? Where is this split line or hose? I’m a mom who needs to save $. I have a p456 code and have already changed gas cap.
on 5:07 part of your video, at the other end of the metal tube, the hose is also cracked.i got the same on mine.is that really like that or is that a crack?
good eyes.. it is a split/crack but that's just a protective rubber sleeve over the metal pipe/tube.. no vacuum leak there.. but a little electric tape would be good there to keep the split from getting worse on mine and yours..
I'm hoping for some insight with your knowledge. Know nothing about emissions except car won't pass inspection. I have a Lexus ES330, just spent 900 to have "both front upstream oxygen sensors" replaced "(bank 1 and 2 air fuel ratio sensors)", I suspect they're the same thing (just reading from the invoice)? 2 wks later my check engine light came back on. Took to Auto Zone to have them plug in the OBD2 scanner, code is PS0442. Has a new gas cap (drove off without mine) several weeks prior to repair oxygen sensors which was a year overdue. Will the PS0442 not pass inspection, and would your quick fix (if that's my issue) enable passing? My mechanic says what he replaced and the new code are separate issues, if so I would've thought after testing the car after repairs would've shown another leak, no?
Many things can trip P0442 but yes, if you have the same issue then fixing it and clearing the check engine light should enable passing.. What led to having the oxygen sensors replaced? Was it a different code or the same P0442 that returned two weeks later?
i turn the gas cap and hear the click. does that mean i turned the gas cap tight enough. i can't remember if there suppose to be play in it still. your thoughts?
@@mannypailma4852 Sorry, no idea.. And if you take the old hose to auto parts store to size match be careful cause that old hose is likely stretched out.. You may need smaller diameter than what it matches now..
I saw two thicker lines below that each had clamps on them.. If that's what's leaking on yours (a line with a clamp) I wouldn't think an o-ring would be involved.. But, I'm not sure, and I don't know what those lines are..
hope this fixs my code. gonna try it out took it to the dealership and it cost $170 for them to find the code and estimate $420 for the work to find the leak with a smoke machine/fix it. hell no.
Links to parts are in the description.. This is the full vacuum line assembly:toyotaparts.lagrangetoyota.com/oem-parts/toyota-vacuum-hose-2382020210 If yours is split like mine in the video you can just replace that section.. Mine was 1/4" vacuum line.. Any auto part store will have this.. I replaced just that section for $1.49..

Absolutely amazing informal video ! I checked that exact spot and BOOM huge leak, just got the car 3 days ago and I love it
yeah seems to be a common failure point.. glad video helped..
This video is a big help, I check the vacuum hose on my Sienna and see the problem right away just like what you say in your video.
glad it helped.. thanks for reply..
Fixed half the problem 😂.. The hose on the left is cracked way worse then that other one you fixed.
Wrong.. That's not a vacuum line.. Only a protective sheathing over the pipe..

Will look on my ES330 at this spot. Another spot of a hose near the airbox is torn pretty well.
cjrciadt Do you know which are part numbers of these hose on your Lexus es330?

Found same leak on my 2002 Lexus Es300 with 250 000 miles.Thanks Bro!
yeah seems to be common with this engine.. thanks for reply..
I found the leak on my ES330 same place. Already changed the gas cap and check engine light came on right away. Thank you !!! Saved me a couple bucks
You are welcome.. Thanks for reply..
that cracked with such accuracy on my 96 Avalon, replaced it with a 5/16 hose from AAP or AZ or OR parts stores.. thanks so much
You are welcome.. Thanks for reply..
Checking in with a 2001 Lexus es300 with a crack in the same spot and the same codes! Only got to the cap before finding this and hoping for the best!

Yeah it seems to be a common failure point with this engine based on comments and thumbs up.. 2.5 years later my electric tape fix is still holding..
If mine stays clear, I'll just call it good with the electrical tape too.

Thanks for great tutorial. Followed it, and error code cleared. small piece of black electrical tape for the win.
Glad to help.. 2.5 years later my electric tape repair is still holding strong..
do you see the split on the other end of that hose?
yes i see the split but that hose is just slid over the metal line for protection
Does this apply for 2005 Toyota Camry se v6 3.3l special edition?
Not sure if it will be exact but mine is 05 Highlander with 3.3 V6 so it should be very similar..
there is the evap valve with a hose on both sides and whats is the best way to measure the hoses if i can not find online;
My leak was coming from the line on the little solenoid mounted to the intake box. Any chance you know what that component might be called so i can look into getting a new hose?
Sorry I do not know the name of that part.. But if you take the section of hose to any auto part store they should be able to match the hose size/length..

Exact problem with my 204 RX 330! Thank you. BTW did you catch the split at the other end of the metal pipe (to the left at 5:00).
I did see it but on my engine that's just a protective rubber sleeve over the solid metal pipe/tube.. No vacuum leak..
Thank You, I think I know by now where is the issue in my Lexus ES330 Car.
Big thanks will be looking into this before anything else

05 ES330. Worked!
I'm hoping for some insight with your knowledge. Know nothing about emissions except car won't pass inspection. I have a Lexus ES330, just spent 900 to have "both front upstream oxygen sensors" replaced "(bank 1 and 2 air fuel ratio sensors)", I suspect they're the same thing (just reading from the invoice)? 2 wks later my check engine light came back on. Took to Auto Zone to have them plug in the OBD2 scanner, code is PS0442. Has a new gas cap (drove off without mine) several weeks prior to repair oxygen sensors which was a year overdue. Will the PS0442 not pass inspection, and would your quick fix (if that's my issue) enable passing? My mechanic says what he replaced and the new code are separate issues, if so I would've thought after testing the car after repairs would've shown another leak, no?
Many things can trip P0442 but yes, if you have the same issue then fixing it and clearing the check engine light should enable passing.. What led to having the oxygen sensors replaced? Was it a different code or the same P0442 that returned two weeks later?

You're welcome..
Thanks, I just found the same issue.
glad to help.. seems to be common failure point..
i turn the gas cap and hear the click. does that mean i turned the gas cap tight enough. i can't remember if there suppose to be play in it still. your thoughts?
i also turn till it clicks and there is still play in mine.. it doesn't get tight like the oil fill cap for example..
Thank you this is a great instruction how to do it ?
Made the day 🔥
The left side hose on that line is also cracked
that hose is just slid over the metal line for protection
That engine sucks to change rear spark plugs
