2004 toyota sienna p0442 small evap leak easy fix

[@AbideandBelieve]

What are the exact sizes of rubber hoses that are needed to replace these with? I also have the 2004 Toyota Sienna and this is happening with mine as well.

Thank You it’s aGreat information

[@cndvd]

Time to probably change that purge valve solenoid too, P0442 may show . That gets brittle and will crack. Get a OEM denso one on hand. Those cheap ones may not run your engine correctly …but could work.

Would this make a hissing sound and then loose acceleration? When I turn off the car and wait I can drive 1 mile

[@kjwabay]

Is it 5/16 inside or outside diameter?

[@cndvd]

Cool got to go check mine, code keeps coming on. Hope it’s the problem.

What is the small black box with the two hoses next to the PCV solenoid?

[@fixergood]

thanks for watchin I'm not sure but it looks like it's part of the evap sytem possably a vacuum canister for assitt?

[@mjtiptonjr]

@@fixergood I’ve replaced damn near everything except that and still have P0441 🤬

[@bygonebob]

As far as I know, that black box with the two nipples is an EVAP Surge Tank. It holds an extra small amount of vapor (as a reserve) from the canister to assist in situations where you need instant acceleration when you press on the gas pedal. God bless.

Is it dangerous to drive it with that problem

[@fixergood]

thanks for watchin ,it violates epa standards so if you get smog checked it wont pass

[@bygonebob]

No, but you will lose gas mileage. God bless.

Thank you hopefully the cracked return fuel will fix it

[@jaehohwang8125]

what size hose did you replace with?

[@fixergood]

I would have used either 5/16 or 3/8 fuel hose,thanks for watchin
