Wow, good stuff for diagnosing the EVAP system, Dogfriend.

I'm sorry for the loss of your buddy. They do indeed become part of the family, and are greatly missed.....

Sderaad, the most common cause of this code is a loose fuel cap, or damaged O-ring seal, so check that first.

Thanks. I'm still at the stage where I expect her to be right here next to me, but she's not here anymore. She had a good life, but I'm very sad that she is gone now.

Thanks for all of the excellent info. I'll try the gas cap first, but now I know where to go if thats nor the fix.

Thank you all.
