yes, Sienna V6 hot engine in small bay really hard to plastics and rubber. That plastic pipe next after the thermostat is well-known to blown up suddenly and leaks all water.
My 200 Toyota Camry 3.0 Liter engine tripped the P0446 code. How can I tell which one of the 3 evap modules you mentioned under the hood needs to be replaced?
Nice job. What is the measurements of diameter of the hoses you replace on the Evap hoses with the yellow zip ties? Also is that a fuel line hose you replaced them with?
One bad bump or an especially rainy day could brick the ECM (and the whole van). If everything else was perfectly taken care of (unlikely, considering the condition under the vanity cover) maybe worth some extensive rehabilitation. My guess: It isn't. That's a timing belt engine too. At least the transmission fluid has a top fill with dipstick. I had an '05 LE 8-seater with towing package (VIN was a 4T or 5T prefix)... The power door motor was small and the door problematic. Also had a gear shift solenoid problem. Worse was that it sprung an oil leak at 55k miles living in the high desert. Not my favorite Toyota, but comfortable for long trips and handled OK speeding through the mountains. A sedan rear-ended me on the freeway and the "cage" protected us well. The other car pushed under instead of crushing the passenger compartment.
I have A question for you I have a 2018 Toyota RAV4 xle it has 42500 miles. But, my question is I changed the oil from 39,000 miles 0w-20 oil and my plan is can I do an oil change after 3,500 miles. Also, can the dealer refuse to do it or not?
The vanity cover causes the wiring harnesses to overheat and crumble, eh? Is there any problem with taking it off, inspecting the wiring and hoses, then leaving it off forever?
Yes, that fancy cover is the major contributor to the heat problem by trapping hot air and slowly cooking all the plastic and rubber components underneath it. I always advise family and friends to take those vanity covers off and never put them back on. God bless.
I had same codes on my 2006 subaru sti.. purchased an autool sdt-206 and found leaks. Repaired all. Awhile later got a po448 and po447 was unable to repair. Did not have bi directional scanner. Gave up . Total spent at repair shops. 2800 dollars total . Faulty pcm and corroded wires.
Like to keep vehicles a long time, and have a garage? Every time you arrive home, open your hood and let the engine cool off as fast as possible. The longer the plastic and rubber stay hot inside there, the faster the wires and hoses deteriorate in the heat, which the insulated closed hood efficiently traps. A general rule in chemistry is that every 10 degree C rise in temperature roughly doubles the speed of a chemical reaction. So plastic and rubber will deteriorate much faster hot, than cold. You can keep electrical tape from ever unwinding by wrapping your way back to where you started taping, and putting one of those electrical zip ties over the last wrap of tape. Then it can never unwind and get caught in belts, or burn on hot exhaust parts. Cut off the excess nylon after you tighten the tie. It is always good to ask, 'now what can go wrong with this idea'? Hot air rises. So you might consider leaving the engine cover off, so as to not help cook the hoses and wires living right under it. Usually no water can get on top of the engine wiring connectors. Those covers just look nicer than machinery. And the dealers don't want people to see how complex the latest cars are. More parts mean more parts to fail. Rodents can chew through aluminum siding. Moth balls will sometimes discourage them. I think Honda makes a special tape which you can put on wires to discourage them, but it is somewhat expensive. Sticky rodent traps work too.
@@paulparoma Thanks. Just beware that on some of the newer vehicles there might be some kind of interconnection between the hood and main computer, such that the hood being open might cause the computer to not go to sleep properly, if the hood is left open. But since you need to have it open to check the oil and coolant, I doubt it would cause problems. The latest computer programs in new vehicles are so complex, that any crazy interactions are possible. On my old 2000 Expedition, the under hood light just stays on for about a half hour, then shuts itself off so the battery doesn't get drained. But on the 2021 Expeditions if the hood is left open, the computer might not shut everything down like it should, and that might eventually drain the battery. Although it would probably take a few days since the computer doesn't need much power to stay awake after the engine is off.
@@billsimpson604 Insane. Luckily, my 2005 Scion xB has none of that. But it doesn't like to sit for too long, so I have it on a trickle charger most of the time, since I drive little.
Planned obsolescence. In Japan they make you buy a new vehicle every decade or so, not sure but they know after so many years the plastic and rubber just doesn't hold up. Still most will go 300,000 miles, so it's better than the 75,000 miles that used to be the goal of American companies 50 years ago, long enough to get past the warranty period. GM upped the bar and made the transmissions that could go 150,000 miles, so Ford had to figure it out. They supposedly finally hired the GM engineers and the trick was to pump oil to parts immediately rather than wait for the oil to spread after warming up, requiring thinner oils. Japan upped that by designing the overhead and dual overhead cam engines, much simpler, with less problems, and many more miles. People don't realize the advantage till decades later, the Japanese vehicles still work. So now most every car has those engines, but the reputation is shot until decades later they will last. Yes, my Toyota van with 240,000 miles has disintegrating plastic, just like in this video, besides these wiring harnesses, the plastic on two radiators fell apart.
Good video and simple to follow. Except..!! I don't think Rats and mice bit the wiring. I believe heat,cold, dust and year's made it like that. Looking at the plastic how bad they we're..all falling apart. Do to age.. Maybe..??
I'd bet on rats eating the wires, not just age. I've seen our main power line to our house bitten through by squirrels, and a brand new unsold van completely eaten out by rats.
The rodents chew on the wires of certain makes/models because the wiring jackets are made partially out of SOY. Yes, soy. In other words, FOOD. Rodents can smell the soy/food and will chew on the wiring causing all kinds of trouble.
Three words - inspection, inspection, INSPECTION!! Rubber parts need to be inspected annually. Additionally, any some silicone or 303 Aerospace protectant to keep rubber pliable.
The grace and peace be with you from the lord your God our father and his son Jesus thank you, but how many of you know about the good news repent and believe in the gospel because the kingdom of heaven is at hand and crack your word the Bible and continue blessing you!

Sienna's were awesome then. They're awesome now. That's why the cost what they do. If you're gonna repair a Toyota or any car- use the correct OEM parts or nothing. Lot of so called mechanics only repair with the budget they're given so it guess it mostly the owners fault..
On chewed wires like that I wont use electrical tape...That fix is only short term since the glue on the tape will heat up and eventually the tape will loosen completely. I choose to use my cordless hot glue gun and coat the entire area. Problem permanently fixed.
Peter The Great; simple, slow and precise explanation; easy to follow. Thank you.
Looking fwd to future installments, great content, thank you. Have a great day Peter.
Thank you! Your love of the craft and the brand is truly appreciated! Love your chanel
My 1998 Toyota Sienna has the 0441 code and your excellent step-by-step diagnostics and fix were very helpful in fixing mine
Having similar issues with my 2005 3.3 v6 Camry, thank you for the video!
I really enjoy watching your videos. Thank you sir. They are of great help.
yes, Sienna V6 hot engine in small bay really hard to plastics and rubber. That plastic pipe next after the thermostat is well-known to blown up suddenly and leaks all water.
There are cats that run around our neighborhood and I used to get mad at them. I shouldn't because the mouse they kill may be a wire-chewer!!!
Great vid, thanks for the help!
Great job as usual Peter, you catch a lot of things that many people over look🌟
Impressive Diagnosis 🤔
Thanks for posting
THANK YOU SO MUCH! You just saved our non profit $120!!!
What would be the fix to that? Lmk. Awesome job peter
Thank you 👍

The cause is the beauty cover , I removed mine forever
446 can be caused by canister problems too if I'm not mistaken.
I have A question for you I have a 2018 Toyota RAV4 xle it has 42500 miles. But, my question is I changed the oil from 39,000 miles 0w-20 oil and my plan is can I do an oil change after 3,500 miles. Also, can the dealer refuse to do it or not?
I have the same problem in a 2003 Toyota Sequioa. How do i found out wich valve

What if I only have p0446 code? Would you recommend changing the same part?
Thanks!
lolz you really like to crunch things..good video btw
WOW very kool great info. AAAAAAAAAAA++++++++++++ again great video I liked it a lot keep up the great work

Very helpful. If I may ask what size hoses did you use ? Great new shop, best of luck
They are 5/16

Bill, great essay. Luckily, I don't live in a very hot climate, but will certainly heed your advice.

OEM part #25701-20220 is the assembly set. As low as $225 online. Mine vehicle is 2006 Toyota Sienna CE.
I thought p0446 was associated with the canister or fuel tank fill valve.
👍👍👍👍
Thank you Peter. Be safe brother!! Rock on California :)
Tractor supply sells peppermint 4 packs in a box. Rats hate the smell. I stuff one the hood area. It helps.
Great video! Does anyone happen to have the part number for the hoses? Thanks.
OEM 25701-20220 is the full valve assembly. Google it -you will see what is included.
rubber and plastic from 20 years ago just isn't the same as what we have today :-/
I have long-ass EVAP lines all over our 2002 4Runner.
Nice to know Toyota uses top-quality rubber and plastics.
After 15 years I think it held up fine.

Peter, What is the code for rodent bites?
I think it is R0911. Having cats can help. And don't keep any kind of food in the car.
Yes, the code is 🐀🐁
3:08 is that the vacuum switch valve?
Yep
Peter you didn't catch the gas cap
👍👍🎈🎈😀😀
Something yells me Peter is changing (replacing) those injector conections.
Yes! Let's see it
I wonder if you can just delete the whole EVAP system and have a happy computer?
and an unhappy EPA 😂
Plus cel
Which is is the best generation for the sienna?
This one 2004-2010
Muchas gracias medina
Peter what you need to replace when you get the code p0441 in a toyota tundra 2002 v6. I already changed those vaccum hoses.
Thank you very much.
