Same thing happened to me. I just delete the code. I also switched 180 degrees the gas cap. The seal on the gas cap always goes bad.

Thank you...that's what I figured...99% of the time its the gas cap for that stuff.
Ordered a new cap because well the other one has the "tether" broke which always annoyed me. Once that arrives will clear codes and go from there.

I'd bet it was an old clogged valve. One of the other members wrote about opening the old valve and cleaning the carbon and oil gunk. I think I would just replace it and throw the old one in the trash. Keep us posted.

We will see. It's funny after I shut everything off and post here, I think "Oh yeah, I should have checked this". It is 95F and 80% humidity. Part ordered.
Looking for a quickie o-scope tool from amazon to see/graph voltage changes across terminals for future repairs. I would like to graph if the voltages are commanded from the ecu. Don't think my multimeter can pick them up.
Now, I will not try to incriminate myself going down this rabbit hole...but I noticed an acceleration cutoff (not speed), just total lack of power when stabbing it full throttle say at around 75-80 mph after hitting it hard a couple times. I hope this is the issue.
Anyways, the ole gal was great on the past few drives.

Was the valve.
I took a semi-gamble and ordered a Beck-Arnley from Rock Auto for a tad over $30. Appears to be OEM just based on how it looks and the weight is within grams of the original.
One side had a crimp clamp which wasn't hard to remove. Fortunately, I have a stash of hose clamps.
All in all, simple fix. I was curious, but both read open with ohm meter across the terminals. But when I actuated the new one with DAS you'll know it. It fires/clicks several times a second so it is a good test.

You motivated me!! Just ordered the part. As you and others have pointed out, it isn't expensive.
