Great video buddy. Very helpful. I have a 01 Camry with the same codes. Keep making these kinds of videos. ✌️

Thank you sir for making this video. It has helped me a lot in understanding the steps electrically and mechanically of looking into my own codes P0440, P0441 and P0446 (all show in my OBD scan). Will try some more troubleshooting in the summer when it gets warm.

Had Incorrect purge flow code on my 99 corolla. Was getting rough starts after pumping gas and some engine vibration. I replaced the purge valve under the hood which solved the rough start issue. Engine light cleared then came back on after two days. I'm thinking if there's still incorrect flow, the next thing to replace is the vent solenoid next to the canister.
