I'm a bit confused. When the light first came on, I took off and installed the gas cap. Within a couple of days, light went out.

Got gas, light came back on. Figured it's the cap, replaced it with a brand new OEM from the dealer. Light still on after about 300 miles of driving.

Time to look at some other possible culprits. Is there a way to check the charcoal canister or do you just have to replace it?

Bump. Anyone?

I did check the vacuum lines yesterday. They all look ok, visually. When my mechanic recently did work, he must not have reconnected a couple of the hose clamps. So, I took care of that. So, we'll see if it clears on its own. If not, then it is probably the canister. Is Toyota OEM the only option?

Actually pretty easy fix and pure coincidence.

So, I went back and decided to touch the length of each vacuum line with my fingers when one of my fingers snagged on one of them - it was split in half right where it went onto the metal fitting for the intake. (there are a couple of them that go to the metal fittings on the intake. IIRC, this was the one that was larger diameter and closer to the front of the car, slightly to the driver's side).

So, I went to the parts store, bought a couple of feet and replace them. And voila! I think it cost a total of $2. Code never came back.

The reason I didn't find it the first time I looked at the hoses, was because I just looked at them with checking them out all around or looking really close for cracks. However, what I found was a split, not just minor cracks.

My car had over 200K on it. Once I decided to replace one, I replaced them all - they were all dry to some extent.
