A little over a week ago, I disconnected the battery in the Camryvan to clear a check engine light. Managed to pass emissions like that so I’m good to go for two years.
I just drove 900 miles straight and the light is still off, so I think my initial assumption was correct (there was an ECM upgrade that hasn’t been done yet on my van).
Hope you all are well. Watching Long Beach riots on tv, this is nuts.
