WOW this must be the ALL-TIME PARTS CANNON RECORD!!
This 2010 Toyota Corolla has had the Check Engine light ON for 2 years; codes P0441 and P0455 for the EVAP system.
After throwing THOUSANDS of dollars at the car, the Owner is ready to BURN IT TO THE GROUND!!
Let’s see if we can exorcise the EVAP ghost so this rusty econobox can pass the Emissions Inspection 🙂

hi..why dont u do a system reset because you have it in your scanner..!!!
Why on earth would you replace a air filter box MAF sensor they have nothing to do with EVAP leak's Yes again another reason why you should never throw parts at stuff and get things fixed correctly.
Love your cliffhangers, Ivan!
I had thesame problem whit a corolla the only thing that I noticed code p0401 purge incorrect flow onthe freezframe the car was on open loop
Do not perform test when tank is more that 90% full! Good thing 90% of your customers bring you their vehicle with less than 10% in the tank. LOL
my next step would be to do the manual test again but this time with that vent hose reconnected. It looks like you left that hose disconnected during the test. I think it's possible that there is a blockage in the vent hose going to the fuel cap area causing the pump not being able to exhaust and thus not able to create a big enough vacuum which makes the system think there is a leak when in reality the pump is limited by the blockage in the vent hose.
Damn need the part 2
hmm, original cannister broke up and left debris in the line to purge valve/engine, they replaced everything but didn't flush and clean the lines out?
I've had that issue multiple times in the past, dating from 2012 back to 1980's carbureted vehicles. my solution was always placing a fuel filter in line directly in front of the purge valve.
You're comment on the weak vacuum pump makes me wonder if that's the problem. The module it lives in doesn't seem to have been replaced. I'd also check all the "plumbing" to make sure the hoses are going where they're supposed it. I could see someone getting that wrong and no one catching it.
replace everything 50 times and never fixed the real issue. oh lard
Almost tempted to just change what hasn't been changed. 😉
