Damn. Mine had this issue and sure enough it was the gas cap. The gas cap has a 1 click close. Well I didn’t close it and had the 1 click. Who would have thought. Thanks
Did you test yours after the new cap? Mine pulls a p0441 and I changed the purge valve but still has error. I did a smoke test and regardless of gas cap there’s a ton of smoke coming out of the gas cap area. Mine appeared to come out of the charcoal canister vent tub leading back to the gas cap Did you smoke test after your gas cap? I’m trying to figure out of the evap system is open and venting when the car is off or if it should be full sealed. I did see another video where they manually closed the charcoal canister valve to create a closed system.
@@blockahwood So, I did smoke test and smoke was coming out from around gas cap, not from the gas cap, around it. You need a obd2 that you can command switches. I was able to command the vent valve which is normally open on the charcoal canister closed, after this I was still getting smoke around gas cap. Charcoal canister vent just vents out around gas cap. So I replaced the entire charcoal canister and vent valve assembly which is directly above the muffler. I had to take the muffler off and heat shield to get to it. That was about two weeks ago and so far so good. Mine is a 2017 Highlander.
@@jonathanjones5315thanks, I appreciate the info! I believe this is exactly what’s happening to my 2018. I’m going to look into the canister and vent valve over the weekend.
Great video helped fix my issue. Found the hose from engine to solenoid had slipped off. Thanks.
Awesome. I’m glad you figured out the problem!

My pleasure. It is always nice when the fix is easy!

Mine is doing exactly the same thing. Did you figure yours out?
@@jonathanjones5315I’m having the same issue as well, took apart that whole assembly behind the gas cap for nothing.. still trying to find the issue.

So….. did you “fix” the problem by replacing the gas cap?
Yes. New gas cap installed and haven’t had any issues since
