Hello this is my first post however I have spent quite a bit of time on this forum recently.
I have a 2010 RAV 4 Limited AWD v4 with 95,000 miles.
This started months ago when I got the following emissions codes: P043F, P043E, P2401, P2402 and P2419.
My first thought was it was just an emissions thing, I live in WA state so I'm not required to pass any of those tests so I figured it wasn't a big deal.
Then I realized that it does disable 4WD and traction control and it's not a coincidence those lights popped up too.
My first line of action was purchasing a new gas cap from Amazon, 77300-06040. However this did not work, although I would be open to revisiting this because I'm not sure if its an OEM part.
After a few months I decided I'd try to fix this and replaced the EVAP canister with the 2007 Scion part and changed over the mounting brackets, like I had seen on other threads of this subject. Part is 77740-21011.
I thought I had fixed it, cleared the codes with my scanner then a couple days later I got the engine light again. This time though, there are only 2 codes which are P0441 & P0455 (large leak).
Since P0441 mentions incorrect purge flow I decided I'd replace the Purge Valve Solenoid with one from Rock Auto. Cleared the codes again and now the same two codes are back.
I had also came to the conclusion that the old one was stuck closed because, I disconnected the hose that runs back into the charcoal canister, let it run for awhile but never felt any sort of vacuum.
Now I am sightly at a loss of what do to. I am definitely not a mechanic, or super car savvy but I have a lot of tools and a fair amount of patients to work on my car.
Need help coming up with a next step, whether that is checking out other potential issues, or sending to a mechanic so they could do a smoke test to identify the issue.
I know there is a vent valve solenoid that I haven't looked into yet, but have probably written enough and any suggestions would be appreciated!
