Thank you very much for this video. I recently had to drop the gas tank to fix a 3 foot crack in my rear frame on the driver side to AutoZone to have the code machine hooked up and this all happened after I put the tent back in so I unplug the battery in the code or the dash light stayed off. Thank you though something else I learned about my Toyota I appreciate your time.
At close to 150,000. miles, I began having a few minor problems mechanically. I replaced both the charcoal canister and the purge valve. The purge valve was the culprit, but the Tacoma seemed to run like new after both were changed. If your truck ever seems to have any trouble starting, it probably is also time to change out that starter relay in the fuse box too. My truck has the manual transmission and it has never had any real problems.
i have P0440 ( i have already replaced gas cap) reset code and it returned and now it also has P0441/446 as well.,, im thinking purge valve and can sometimes smell gas outside vehicle as if i just finished refueling
@1:09 is the lower hose the one that goes back to the intake manifold? Is that a good place to do a seafoam spray treatment (vs taking off the entire air filter box to get to the throttle body)? Or is it the side hose (right side of the photo) that goes back to the intake manifold?
Great video subbed & upped ya. Got a 2010 Corolla 65K Miles and a PO441. Based on your video I replaced the purge valve and the gas cap with OEM Toyota parts. Cleared code and a week later it threw the 441 again. Now I smell fuel back by the fill cap area. I'm the only one that fills the gas. Today I will get under there and see what the hoses look like. Hope its not the canister that's a expensive oem part. Btw, where is the PCV valve please I can't seem to locate it on the valve cover. It must not look like the standard pcv valve. Thanks for your help let you know what I find.
I got under the rear of my car today and its a horror show. In addition to the fuel pump and its output there's a large vapor hose that goes to the canister. There's also another small plastic tube coming off the gas tank I found that tube has a small chunk missing out of it. And it is weeping fuel. It is integral to the tank. Only hose that comes with the tank and you cannot buy it by itself. I am pretty screwed. Trying to come up with ways to fix it. It must have had a pin hole which set the P0441. Then got larger to the point I smelled gas at the rear drivers side tire. Its a strange hose with hard plastic disks. Looks like an armored hose. Wish i could post a picture.
Thanks for making this video. I'm chasing a P0441 on a 2006 V6 4Runner. Has a strong smell of fuel vapors by the gas cap. Have replaced the gas cap and purge valve. Didn't fix it. Filled the truck with fuel with the engine running and fuel ran down the fuel filler neck lines. So I thought there was a hole in the filler neck and replaced it. That's when I learned there's a vent up there by the gas cap that appears to come directly from the leak detection pump on the charcoal box. Fuel was pulled through this line and then leaked back down the filler neck lines. Have also heard gurgling noises coming from the fuel cap area when the truck is on. Current gut feeling is the leak detection pump is stuck on or stuck open? Is it even possible for the leak detection pump to get stuck on? Any advice here would be very welcome. Thanks!
I sometimes smell gas and everytime I fill my gas up from empty it clicks after like 5$. So I never know how much it’s filled or not I just rough guess. I have code 441,445, and 446. I have a 2005 Toyota Camry 3.0L v6. Any help?
Ok this its the situation The car show checkengine VSC And the other ligthts on but when I check with obd show me PO441 so thanks for your video but we need more orientation thanks
Hi very informative video. I have a 2016 Corolla with strong fuel smell coming from AC vent first 1-2 min after being started in morning, the clear normal air. Any idea of what could be the issue?
Would this code cause it to go limp mode and shit you down? I also have the dreaded p261b which most say it’s the engine water pump. I figured that is the code that causes it to go limp and cause you to have to pull over and shut her down.
It is most likely the P261b code. The only component in the EVAP system that affects how the engine runs is if the purge valve is stuck open, which usually gives an engine running rich code.
Yes, question. I searched online and came across info stating that the purge switch, which is near throttle body under hood in my 2007 Camry 2.4, would have no suction if a specific hose was disconnected while engine is running. Is that true?
@@HVAC_Mechanic Okay, thank you, so my problem is elsewhere as it is closed. Not being a mechanic per day I have to hunt the problem down with limited knowledge and tools. Gas cap seems good, no cracks in ring, I cleaned it off good so now onto other things to check. What a headache.
02 Celica GTS 2ZZGE. If I fill up the tank, to the point of one click on the pump, the car will idle very low or stop, but runs fine while driving, and after a few minutes goes away. Could this symptom plus the code mean my canister?
I've replaced the purge valve by the valve cover the gas cap and the entire charcoal canister everything and it's Toyota parts still have p0441... I am completely lost at this point.
My code only comes on when I fill the gas tank all the way. If I put like 90% full it won't. So I guess it's the Canister. Otherwise the code would come on all the time.
I’ve replaced the gas cap, purge valve, and canister but I’m still having the engine light on. I’ve checked all my hoses and they look good, I’ve replaced the ones that didn’t. Is there anything else I could try
@@HVAC_MechanicI replaced purge valve and replaced some hoses and codes went away, But week later I got P0171 P0174 P0441 codes and I have trouble starting engine after I fill up gas tank. I cleaned Mass Airflow Sensor but did not help. What do you suggest?
@@unknownqoz Leak - replaced clamp on intake boot. But then had codes PO171 and P0174 had to also replace MAF sensor and Purge Valve. Make sure you get Toyota Purge valve.
That's the code for the air intake manifold or sensors that is connected to the engine. You should check it to see if there is any problem. Mine showed that code only once when I touched removed the air filter because I was trying to change my water pump (p261b) code 😅
There could also be an issue with the wiring... possibly the power connector to the solenoid valve... could try cleaning it out w/ electrical contact spray to start..
Hi! I believe I need to change my charcoal canister. When I take my gas cap off, I hear gurgling noises coming from it. Could it just be a clogged hose, or do you think I need to change the entire canister?
Back story, I already I changed my gas cap,purge valve solenoid, and a hose connected to the purge valve solenoid. The codes went away for a while. Now I have P0445 and P0441.
P0456 but if it is paired with P0441, P0440, and/or P0446, there is most likely a solenoid failure, leaking charcoal canister, or a more complex EVAP leak.
@@ramonvargas5928 Would you happen to know the name of all the hoses that can cause an evap leak. Ive done everything except change hoses under the car.Thx
This code came up before and I purchased and installed a new gas cap. Then it happened again then I checked the gas cap, released the pressure (which was considerable) and it the light went off. Same thing happened again today, I released the pressure and now it is remaining on. I'm curious, is there a trick to resetting the computer so the light goes off?
If the vehicle is older than 2010, the code can be cleared with a scan tool or by removing a battery cable. 2010 and newer, it will need to go through a drive cycle to clear the code.
Hey, can you keep doing these where you talk super, super fast and zoom through everything so we can’t understand what you’re saying or see what you’re doing? Thanks! 😡
Very easy to understand. Thank you so much. I had a 2010 Sienna always doing this code. Now my 2016 Sienna is up to the same shenanigans!
Very helpful video was about to go spend money on the evaporator switch and remembered my gas cap stopped clicking a few fill ups ago
Walla !! $30 fix

This is the best explanation. Thank you so much!
I really like your video style and this video helped. Thank you sir. I hope you keep making vidoes
So I replaced the evap/EGR Valve 2 weeks ago. I was not getting a code, now with the new valve, I'm getting this code. Now 2 weeks later ????
The information was epic thank you brother
For me, it is was the cracked seal on the gas cap
Returned the purge valve but otherwise awesome info.
Thanks for sharing this info - great video!
Like your video , you go straight to the point tks
Use electrical tape on these hoses before problems, wrap them to prevent exposure to air and water, espcially under vehicle
Thanks sir

The PCV valve is under the intake on the block. The intake will need to be removed to get to it.

If you blow on the purge valve it should always be closed. Unless energized
When checking the purge valve for electrical voltage what should we be looking for? As far as what would he the ideal voltage?
I believe it’s 12v

Can any of these be the cause of a slow start when the engine is hot and been parked for half an hour? I’m stuck trying to find the problem here 🥴
Did you ever find a solution ?

O have p0441 and P0455 Do you think it also has to do with this?
Did you figure it out i have the same issue!
Vheck hoses and purge valves. Smoke test is best bet. Worst case replace charcoal evap canister
I stalled on the road… there was hissing sound for miles … then I lost acceleration… could this be the hose leak to evap? 2004 Toyota Sienna
I did get the codes I. The past .. I’d clear them
Having the same code. Replaced gas cap. The code came on and off for a week or so by itself. Now it stays on. Any figure this out?
Then got be other stuff he listed in the video
@@MarlonBrown61 fixed it.
Yes, question. I searched online and came across info stating that the purge switch, which is near throttle body under hood in my 2007 Camry 2.4, would have no suction if a specific hose was disconnected while engine is running. Is that true?
The purge valve should be closed and have no suction on start-up, but the computer will send a signal for it to open at some point.

When an engine has issues after filling up gas, it points to a purge valve that is stuck open.

@@Too-Gq-For-You no. I have a nice scanner that I can clear codes with I've cleared the codes in the truck god only knows how many times
@syty1991 hhmmmm you replaced both solenoids too? On top of the canoster and and on top of intake manifold?
Did you ever figure this out? I am having a similar issue and have replaced most every thing I can think of
I have a 09 Matrix. What should I check if I’m having a hard time filling up my gas tank?
If it keeps stopping while you're putting gas it may be the sensor. Just try to hold it at one angle it should work and don't overfill it
It was the leak detection pump.
My code only comes on when I fill the gas tank all the way. If I put like 90% full it won't. So I guess it's the Canister. Otherwise the code would come on all the time.
Good afternoon, can u tell me where evap can s located on 2009 Camry

That is a common system of a vent valve stuck closed. It's usually built into the charcoal canister.

@@HVAC_Mechanic purge valve and vent valve the same thing ?
They are separate, the purge valve is located in the engine bay and the vent valve with the charcoal canister
@@HVAC_Mechanic thank you much
What's the other code that shows that charcoal canister is bad? I have a p0505 idle air control system code, are they related in someway?
That's the code for the air intake manifold or sensors that is connected to the engine. You should check it to see if there is any problem. Mine showed that code only once when I touched removed the air filter because I was trying to change my water pump (p261b) code 😅
I have P0440 P0441 and P0446 together. Do you know besides gas cap, purge valve, hose leak, canister, is there anything else may throw these codes?
After checking those things, the only things left to check would be the vent valve and pressure sensor.
There could also be an issue with the wiring... possibly the power connector to the solenoid valve... could try cleaning it out w/ electrical contact spray to start..

Where is the purge valve located? Sorry im a noob. thank you
@luism8471 it is located under the engine filter housing, you have to remove it first
Is it possible cause of P0441 is the Water Pump?
I don’t think so. Water pump is not a part of EVAP system.
@@chiya2006 the code for water pump is p261b code. That code means you need a new electric water pump.

It is the same for the new no-gas cap systems. The inlet that automatically opens and closes can leak.
