No, I'm not on any drugs.
Had a car come in today with the check engine light on.
Code was for one of the evap canister vent valves being stuck. But the valve was working fine. So i pulled off the atmospheric vent tube attached to said valve. I found it full of very fine thick spider webs, which were impeding the flow. Because there was almost no flow, the PCM assumed the valve was stuck shut and threw a code.
Cleared out the tube and it worked fine.
This isn't as rare as you'd think, Honda has a service news article about it. Only seems to happen on cars that come from Japan. Yellow sac spiders, apparently, which looking online can cause a wicked bite.
