I'm showing codes P0440, P0441, P0446
A friend of mine says my issue is a bad purge control solenoid valve... the auto part store couldn't help me at all. My friend also says it should take 20 minutes to fix... The little I've found so far online shows me having to drop the gas tank to get to a charcoal canister. Could this canister be this same solenoid valve? Anyone have this issue yet I need to fix my car ASAP since I have emissions due this month.

here is the full report from my car:

Before you do anything, could you check the EVAP hose behind the airbox? I cannot find a picture but you can easily see it if it is disconnected and/or missing for some reason. The plug is right behind the airbox into which the hose goes.

I will check that out soon as I get home. Thank you.

If it's this hose it looks like it's on. Could t be the sensor it's connected to?

Directly behind the air filter box


What else do I do now?

PenQuin

Found the issue. A broken hose that was hiding right in front of my face...

Can anyone tell me what the name is of the piece I'm holding? I has arrows and numbers on the sides... 6, blank arrow and an 8 with an arrow... I'm also wondering what part this is connected too? Looking at the photo what is above my left thumb? this piece connects to the mystery piece... I'm sure someone at auto zone or another auto shop can tell me but if I go with some more knowledge it would be better obviously.... So happy I found a broken hose! I was worried I was going to have a much larger problem but this has to be the culprit!!

Looks like from what I've found its a "Fuel Vapor feed pipe" but zero luck with finding one yet in the auto part stores.... I'm sure ill find one tomorrow!! I also believe the part just about my right thumb is a VSV for EVAP but I don't know what that means... just guessing from some schematics i've found on other threads...

You won't find that part in a parts store. Lexus sells it for around $11. When mine broke I just eliminated it with a piece of rubber hose. It really is just a plastic 90 degree turn. If you do that make sure it is rated for fuel system use. It's about $2 a foot at any parts store.

PenQuin

Will I still pass emissions if I bypass this part?

I did. It is just a hollow piece of plastic.
