Codes P043E, P043F, P2401, P2402 and P2419

Did you happen to push a button on your dashboard, there must be a way to select different settings for the instrument cluster. Check to see if there is anything in the owner's manual in the glove box.

Looks like you're getting terrible gas mileage now. Are you still getting the same codes setting? I don't think the cleaner you used helped the vent shut off valve at all. Right now, with gas mileage that bad, it looks like either the engine is drawing gasoline directly into the engine threw the Purge valve, or the vent valve is now stuck open and it's created a huge vacuum leak and there is a ton of extra air going into the engine. And the engine computer is compensating for it by adding a lot of gas to the air/fuel mixture. What are your oxygen sensors reading? And what codes are set?
Either way messing with the canister assembly made the situation worse.

I saw the 9.9 and thought that was the mpg, if no codes have come back then that's good. How is it running? No lack of power or anything? 23 MPG was the average on these vehicles when new. If no codes come back the gas mileage will get better. About 18mpg is definitely better. Try getting it out on the highway, it will help clear out any carbon that may have built up since it was running so rich before.

Well, if no codes have returned yet on the Evap canister I wouldn't worry about it too much. When was the last time you had a regular tune up done? At least spark plugs. Also, those faults on your scan tool were "Pending Faults" did they change into active or Current faults? If those codes come back, you're just going to have to change the Evap assembly. If there were no other obvious issues such as corroded wire connections or anything like that. By the look of the canister, it was pretty dirty, so it's a good chance over the years some of that got into the canister assembly. It's in a place on the vehicle where it is exposed to a lot of dirt and dust.

So, there are no current faults at all? If so, then do a tune up, at least replace the spark plugs and the air filter. I can't see any real live data on your scan tool, so I have no way of knowing how it's really running. There are some better apps to try with that Bluetooth ELM 327. Some App that will show live data of the engine running. Torque is not a very good app, having an app that can provide live data such as, Long and Short Fuel Trim, Oxygen sensor data, Mass Air Flow sensor, etc. Would help to see the overall health of the vehicle. Maybe try MotorData OBD ELM car scanner. It provides a lot of really good live data. I've actually used that in the past.
I wouldn't spray anything into the Purge valve, it might fail if you do that.
In a shop we would do a lot more testing with equipment you don't have, to test for leaks and monitor components with higher-end scan tools. Thats why without a lot of data, and no codes right now, it's hard to tell you exactly what is going on with the vehicle. Everything is computer controlled, you can check the purge valve and make sure it's not stuck open, but don't spray any chemicals into it.
Toyota's are good vehicles, I'd say the best on the market, The vehicle was running rich for a while so that's why I would check the spark plugs for carbon build up.
